Rolling up to a café with a laptop and a portable monitor lets the whole room know that you’re a busy professional who needs to get work done. But aside from impressing the half-caff crowd, portable monitors are a useful way to add another screen to your laptop, especially when you’re on the go. We recommend the Arzopa Z1FC , a 1080p portable monitor that’s good for work and play. If you want the best picture possible, the ViewSonic VX1655-4K-OLED provides a sharp 4K OLED display that looks far better than the competition.
We also tested portable monitors that add capabilities to your computer, like wireless connectivity with the ViewSonic VG1656N , or touchscreen with the ViewSonic TD1656-2K .

Top pick
This portable monitor offers impressive image quality for the price and is also good for gaming.
In our tests, the Arzopa Z1FC outperformed monitors that cost more than twice its typical price tag of $100, and it has a few extra features that the others don’t. We found its image to be sharp, its colors accurate, and its kickstand sturdy and functional in both landscape and portrait orientations. Like more expensive models, the Z1FC has pass-through USB-C charging, so you can attach a single USB-C cable to your laptop for data and power. It also has a 144 Hz refresh rate, which makes motion on fast-moving games look much smoother when it’s paired with a capable computer or game system. Did we mention that it’s frequently just $100?
Upgrade pick
This ViewSonic model has a vibrant, sharp OLED display that offers the best contrast of any portable monitor we’ve tested.
The ViewSonic VX1655-4K-OLED has a 15.6-inch OLED display that’s sharper, brighter, and more visually appealing than what we’ve seen on any of the other monitors we’ve tested. In our tests, colors looked full and saturated, skin tones appeared natural, and text rendered sharply on screen. The kickstand is a small square that flips out from the back of the monitor, and it’s best used in a landscape orientation, though you can put it in portrait mode if you tilt it back far enough. That kickstand also hides the monitor’s ports, so you don’t have to look at cables jutting out from the sides.
Best for...
This high-resolution ViewSonic monitor is an excellent second screen for a Windows laptop, and it adds touch capability.
The ViewSonic TD1656-2K has a high-resolution 16-inch touchscreen that’s responsive and color-accurate. Its 1600p resolution has a bit more vertical space than other portable monitors, making it ideal for those who like to tap between documents or use touch controls on Windows during their workday. We also liked its case, which turns into a useful stand. It will drain your laptop’s battery if not connected to power, however.
Best for...
This uniquely versatile monitor has a wireless transmitter that works on Mac, Windows, and Linux.
The ViewSonic VG1656N comes with a wireless transmitter that plugs into a Windows or Mac laptop and sends video over the monitor up to about 20 feet away. This is one of the most unique features we’ve seen on a portable monitor, and the dongle even works with a Valve Steam Deck to play games. The monitor also has its own battery, which lasts about three hours. However, we noticed light bleed on the lower bottom edge of the unit that we tested, which makes it better for work than watching movies or playing games.

I’m a senior staff writer at Wirecutter covering computer monitors, laptops, tablets, and 3D printers. I’m a certified display calibrator through the Imaging Science Foundation , and I am responsible for all of Wirecutter’s computer monitor coverage.
For this guide:
- I’ve tested more than 20 different portable monitors since first publishing this guide in 2023.
- I also attended the 2024 CES trade show in Las Vegas to get a preview of upcoming technology and saw many of the year’s most anticipated portable monitors.
- Like all Wirecutter journalists, I review and test products with complete editorial independence. Most of the monitors we test are sent by the manufacturer for review consideration, but I return every monitor that’s not purchased by Wirecutter. I’m also never made aware of any business implications of my editorial recommendations. Read more about our editorial standards .
Who this is for
A portable monitor adds a second screen to your laptop if you frequently travel or don’t have a set place to work every day. Some portable monitors, such as our top pick, can even act as a display for a desktop computer or a handheld gaming console like the Steam Deck .
Portable monitors offer a neat way to take a full-fledged work setup on the go, but they’re not the best option if you work at a desk. Standard monitors are typically about the same price, much larger, and a bit higher quality than their portable counterparts.
How we picked and tested
A great portable monitor has a sharp, bright screen and easily connects to a laptop with a USB-C cable. It should be a simple and reliable device that doesn’t need you to tinker with it often and can work in both landscape and portrait orientations. We used the following criteria while researching and testing dozens of portable monitors, including top sellers on Amazon and models that were well-reviewed on other websites.
- Resolution: We considered only those displays with a 1080p resolution or higher. However, it’s important to also check the visual sharpness of each model, as cheaper 1080p displays can look fuzzy.
- Color: A great portable monitor should be color-accurate out of the box and have menu options to match the color of the display to that of your laptop for a more consistent experience.
- Brightness: Since you may be inclined to take a portable monitor out to coffee shops, parks, and beyond, it’s important to have a screen that’s bright enough for use in sunny conditions. We looked for displays that output at least 250 nits of brightness.
- Contrast: A monitor with poor contrast looks dull and faded, and its images appear flatter. We preferred monitors that had a contrast ratio of at least 1000:1.
- Price: We considered models priced from $50 to $250 for 1080p monitors, $200 to $350 for 2K monitors, and $300 to $800 for 4K monitors. Price was a significant factor when determining final picks.
- Stand: A stand can make or break a portable monitor. We preferred stands that allowed the monitor to work in either landscape or portrait orientation.
- Size: Most portable monitors range in size from 14 to 16 inches. When we physically compared models, the size difference between 14-inch and 16-inch monitors didn’t change how we used or carried them.
- Ports: We required at least one USB-C port for video and power. Some models provide extra USB-C ports for charging your laptop through the display, but unless your laptop has only one USB-C port and no other way of charging, this feature isn’t crucial.
- Extra features: Some displays have 0.25-inch screw mounting points so that you can mount them on tripods or stands for filmmaking and other custom setups, touch support, or wireless connectivity.
In 2024 we evaluated 21 portable monitors, including models from AOC, Arzopa, Asus, Espresso Displays, and ViewSonic. We used each monitor for at least a day of work in a café away from our regular office, which included typing up documents, working with spreadsheets, watching videos, and chatting on Slack. To ensure that we would pick the sharpest display with the best color, we ran side-by-side tests in which we displayed the same image on two portable monitors for visual comparison.
We also checked whether each manufacturer lived up to its claims for its monitor by using the Calman Ultimate software and Calibrite ColorChecker Display Plus colorimeter to verify the maximum brightness and contrast of each display. This also helps validate our visual assessment of each monitor.
Wirecutter staffers are currently testing how our top and upgrade picks hold up long-term.
Top pick: Arzopa Z1FC

Top pick
This portable monitor offers impressive image quality for the price and is also good for gaming.
The Arzopa Z1FC is a budget portable monitor that punches above its weight, offering a sharp 1080p display and fairly accurate color representation for a typical price of just $100. It has two USB-C ports, a Mini HDMI port, and a sturdy kickstand that works in portrait or landscape orientation. It looks nice in tandem with Windows and Mac computers, plus other devices such as the Valve Steam Deck.
Its 1080p display is better than that of the competition. In our tests, the Z1FC was about as color-accurate as other monitors that cost twice as much, and visually we preferred its picture to all but those of the 4K displays. We watched scenes from movies, TV shows, and YouTube videos and found that the Z1FC looked sharper and more natural than competitors, especially with skin tones; if the colors aren’t to your liking, you can manually change the RGB balance to your preference. The display also reached 300 nits of brightness, getting noticeably brighter than other models, which maxed out around 270 nits and averaged 249 nits.
It’s also good for gaming. The Z1FC can reach a 144 Hz refresh rate, so if your computer or game console is fast enough, this monitor can change its pixels to new colors more than twice as fast as non-gaming displays, producing smoother motion. However, you need to set it to a refresh rate that your computer or game system is capable of running comfortably, because it lacks the variable refresh rate technology that’s found in more expensive monitors.
It has two USB-C ports and a Mini HDMI port. If you’re using the USB-C connection to the monitor and your computer supports USB-C charging, you can connect a USB-C power cable capable of up to 60 W and charge your laptop through it. Using that single USB-C connection to your laptop to both transmit data and receive power is beneficial if you’re using your laptop’s limited USB-C ports for other things. The Mini HDMI port is also useful for any laptop, PC, or game system that has an HDMI-out, as you need only the appropriate cable to translate the full-scale HDMI to Mini HDMI.
Its kickstand works in both landscape and portrait orientations. The Z1FC has a sturdy metal kickstand that flips out from the device and can remain securely positioned at many angles. The kickstand works in both orientations, but you need to rotate the picture via your laptop or desktop PC, since that option doesn’t exist in the monitor’s settings. The kickstand also has a magnet to keep it secured to the back of the monitor when not in use. Similar to our previous top pick, this monitor also has small plastic feet that keep it well anchored to flat surfaces.
If there’s an issue, Arzopa support can step up. We’ve found that budget products from unknown companies with somewhat inscrutable names, especially if they’re mainly advertised on Amazon and TikTok, are more likely to be low quality—that is, either the product is lacking in basic functionality, or quality-control issues make it impossible to recommend. To gauge whether the monitor quality was consistent, we purchased two additional Z1FC units, and they all tested similarly well. We experienced an issue with the ST Table, another Arzopa monitor that we purchased for testing, but after we reported the problem to Arzopa customer support, the company responded quickly and a new, functional monitor arrived about three weeks later.
It’s held up to six months of testing. In mid-2024, we distributed four copies of the Z1FC among staffers in other departments to test over time. One left-handed Wirecutter software engineer said they wished there were USB-C ports on both sides, as they preferred to put the monitor on the left side of their screen. You can do it, but the USB-C cable that comes with the monitor is just barely long enough. They also said that the monitor was great to use outside in the summer, though it wasn’t bright enough to use without an umbrella.
Flaws but not dealbreakers
Some people might not like its kickstand. Compared with our previous pick, which had a wide kickstand that covered half the back of the device, this portable monitor with its slimmer kickstand is a little less stable on soft surfaces. The kickstand still works on such surfaces; the monitor is just more prone to tip over if jostled. On the other hand, this much thinner kickstand takes up less space than those of the competition, making the Z1FC easier to position on a crowded desk.
Upgrade pick: ViewSonic VX1655-4K-OLED

Upgrade pick
This ViewSonic model has a vibrant, sharp OLED display that offers the best contrast of any portable monitor we’ve tested.
The ViewSonic VX1655-4K-OLED is the best-looking portable monitor we’ve tested—its OLED display produces near-infinite contrast and vibrant colors. OLED (organic light-emitting diode) technology allows each pixel to turn on or off individually, so when you’re watching, say, a scary movie and a character peers into the darkness, you’re actually seeing an absence of light. In addition, during our tests this monitor’s 4K display showed more detail and sharper text in comparison with the 1080p and 2K models we evaluated, which made words on screen more legible.
It has a cutting-edge 15.6-inch display. The VX1655-4K-OLED’s display is sharp, vibrant, and bright. When we watched content on this monitor side by side with competitors, every other portable monitor we tried paled in comparison—often literally. Most rivals looked washed out and appeared to be no match for this OLED screen’s fantastic near-infinite contrast. We measured the peak brightness at more than 500 nits, which is bright enough for you to use this monitor on a moderately sunny day, though the screen’s glossy finish can be reflective in the sun.
Its ports are hidden behind the screen. The VX1655-4K-OLED’s stand is a small square puck that flips out from the back; that’s also where you’ll find the monitor’s two 60 W USB-C ports, Mini HDMI port, and headphone jack. The design makes this display look a bit neater than its competitors, where the cable typically sticks out of the side of the monitor. When this portable monitor is connected to your laptop, it runs off your laptop’s battery. To keep your laptop charged without using another USB-C port, you can use the VX1655-4K-OLED’s second USB-C port to connect a cable capable of up to 60 W of power, and the monitor will route the power back to your computer.
It can work in portrait or landscape mode. The monitor’s stand is mainly meant to be used in landscape orientation, where you can change the angle of the screen. It can also work in portrait orientation, but in that case you have to tilt the screen back pretty far to reach the small square kickstand, so it can be a little awkward depending on your desk setup.
It’s very light and thin. At a weight of only 1.5 pounds, the VX1655-4K-OLED ranks among the lightest monitors we tested. Heavier portable monitors ranged from 1.7 pounds to over 3 pounds.
Flaws but not dealbreakers
It’s way more expensive than other portable monitors. The VX1655-4K-OLED isn’t the most expensive portable monitor we’ve tested, but it’s close. It typically costs $500, which is far more expensive than our top pick, but it truly is an upgrade in every way. If you’ve tried a 1080p monitor like our top pick and want to scale things smaller on screen, or know you have eagle eyes and like to fit as much as possible on your screen, then we recommend the pick right below this one, the ViewSonic VG1656N . It’s about halfway in resolution and price between our top and upgrade picks, and it has a built-in battery and a neat wireless feature.
Best for wireless connectivity: ViewSonic VG1656N

Best for...
This uniquely versatile monitor has a wireless transmitter that works on Mac, Windows, and Linux.
The ViewSonic VG1656N is one of the most interesting portable monitors we’ve tested due to its wireless transmitter, which plugs into the USB-C port of a capable laptop, desktop, or game system, and sends video wirelessly about 20 feet. We tested the transmitter on MacBooks, iPhones, Windows laptops, and the Linux-based Valve Steam Deck, and it worked flawlessly on all except one laptop, which we’ll talk more about below. It’s not the best-looking portable monitor, and the device we tested also had a significant light bleed on the screen’s lower left corner, which occurs when the monitor’s backlight discolors darker tones near the edges of the screen. But the wireless capability was just too useful, and we think it excuses a lot of weaknesses.
The VG1656N has a sharp 1200p screen. The VG1656N has a similar resolution to our top pick, but it has a 16:10 aspect ratio , which means there are more vertical pixels. This ratio is especially good for working on documents or spreadsheets, because there’s more vertical space. However, content like movies or TV shows won’t fit as nicely on your screen, and you’ll have black bars that fill in the top and bottom of your picture.
It has its own battery, which lasts about three hours. Unlike most portable monitors, the VG1656N has a built-in battery, so it can be used wirelessly and not connected to any other source of power. This is really beneficial if you’re using the display to present slides from a laptop, for example, as you can place the display anywhere within about 20 feet of your laptop, and it doesn’t need to be attached by a wire to a wall or your computer.
Its wireless transmitter is widely compatible. The VG1656N’s wireless transmitter worked on nearly every device we plugged it into, except the first laptop we tried, the Asus Zenbook S 16 . But when we plugged the transmitter into an older Lenovo with a Ryzen processor it worked fine, and it continued to work fine on laptops with Intel Core Ultra chips, MacBooks with M1 to M4 chips, an iPhone 15 Pro, and a Valve Steam Deck. We’re puzzled by this and have asked ViewSonic for more clarity on the transmitter’s compatibility.
It also has two USB-C ports for wired connections and power. If the display’s battery is dead or you prefer a wired connection, the VG1656N has two USB-C ports and supports pass-through charging up to 60 W. This means you can plug your laptop charging cable into the monitor, and the monitor into your laptop, and your laptop will charge without needing two USB-C cables connected.
It comes with a case that flips into a stand. The included case magnetically attaches to the monitor and can be unfolded and flipped backward into a stand. The stand has a few configurations, including two different tilts in landscape orientation, plus a portrait orientation. If you prefer a kickstand to a case, you’ll have to explore third-party options like a tablet stand .
Flaws but not dealbreakers

When connected wirelessly, the display looks slightly different. Every once in a while when using the monitor you’ll see a slight bit of barely noticeable lag, due to the computer’s image being transmitted wirelessly. We watched videos and worked without any issue, but when testing color accuracy we also found the wireless option to be significantly less accurate, with Delta E values above 5.0, meaning colors will look visibly different from those on a calibrated display. Most people wouldn’t notice, but we don’t recommend this monitor for color-critical work.
It had significant backlight bleed. We saw discoloration of black tones on a significant portion of the lower left side of our screen. This screen is much better suited to working in documents, spreadsheets, and slides, as opposed to watching movies and streaming video games, where you’ll notice these kinds of imperfections more often. If you put all your devices in dark mode, or if you prefer to write against dark backgrounds, you’re more likely to notice these imperfections.
It still has a dongle. The wireless feature is incredibly neat, but the transmitter is still a physical dongle. The transmitter is considerate of other nearby ports, though, with a 1.5-inch cable-like USB-C connector that attaches to a roughly 2-inch-by-1-inch rectangle that’s about a third of an inch tall. It’s just small enough to lose, and I did briefly lose it once while writing this review. We couldn’t easily find a way to buy a replacement dongle, either. ViewSonic sells a different wireless video dongle , but we haven’t tested whether it works with this display.
Best touchscreen for Windows: ViewSonic TD1656-2K

Best for...
This high-resolution ViewSonic monitor is an excellent second screen for a Windows laptop, and it adds touch capability.
The ViewSonic TD1656-2K has a 16-inch touchscreen that’s higher resolution than our top pick portable monitor, but the touch capability only works for Windows computers. If you want touch on Mac, check out the Espresso Displays 15 Touch we recommend in our Worth considering section .
It has a large, 16-inch touchscreen that works well with Windows. When using a touchscreen, we find larger displays are typically better, and the TD1656-2K is well-sized for tapping through the Windows operating system. Touch input was accurate and fast, and we didn’t experience any issues when testing with a few different Windows laptops.
It also has a sharp, 1600p resolution display. Many portable monitors have a 1080p resolution, which is perfectly fine on a 16-inch screen. But this higher resolution 2560×1600 display means text and images look sharper, you have more vertical space than other monitors, and you can set the scaling in Windows to fit more on your screen. This makes the biggest impact if you’re using the display for work, because this resolution makes it much more comfortable to fit two documents side by side or view more spreadsheet columns at once. You might need to experiment with your scaling to make sure elements on screen are large enough to tap, though.
It gets reasonably bright to use indoors and in the shade. The TD1656-2K reached an impressive 332 nits of brightness in our tests, which is high for a portable monitor. It’s not bright enough to use outdoors on a sunny day, but it gets brighter than many laptops and would be at home in a well-lit room. However this bright of a light, coupled with the touchscreen functionality, will blaze through your laptop’s battery if you don’t have it plugged into the wall.
Its two USB-C ports support 60 W of pass-through charging. When the TD1656-2K is connected to your laptop, you can plug the portable monitor into power, and it will pass the charge through itself into your laptop. The monitor supports 60 W of pass-through charging, which is enough for most laptops (except high-performance laptops or those designed for gaming).
It comes with a case that doubles as a stand. It supports two levels of tilt in a landscape orientation and one in portrait orientation. We haven’t tested this touchscreen as a tablet for art or drawing, but if you’re planning to try, you’ll likely want a kickstand that supports a lower angle, and potentially an artist’s glove to keep your palm from hitting the screen.
Flaws but not dealbreakers
It’s more battery-hungry than our other picks. The display’s bright backlight and touch capabilities mean that it requires more power than our other picks, and we noticed our laptop drained faster than other monitors when not connected to power. This pick is best for people who often have access to an outlet nearby, as opposed to our wireless pick, which doesn’t have touch but can last about three hours on its own battery.
Other portable monitors worth considering
If you want a more substantial stand (and don’t mind bulk): The ViewSonic VP1656 has the closest thing to a real monitor stand we’ve seen. The monitor has a thick, segmented flap that flips out from behind the display and inverts into a stand. The monitor is lifted a few inches off the table and can be tilted up or down. There are other configurations for the stand as well, but its biggest downside is that it’s really bulky, and the whole thing weighs more than the average portable monitor. But it has two USB-C ports, a Mini HDMI, and an average color accuracy around Delta E 2.0. (We recommend checking out the link just to see neat monitor design.)
If your computer doesn’t have USB-C or HDMI ports: The Asus ZenScreen MB16ACV was our previous top pick, and it’s still a good monitor. It offers a 15.6-inch display with a 1080p resolution, which looks good whether you’re typing up documents or watching videos. Thanks to its integrated stand, you can use it in both landscape and portrait orientations, and it can connect to a laptop via a USB-C cable. What sets it apart is its ability to download additional software that lets you use a full-size USB cable to transmit video to the portable monitor, so it can also work with older laptops or as a smaller, secondary monitor for desktops.
If you want to add touch to a Mac: The $550 Espresso Displays 15 Touch is a 15.6-inch 1080p display wrapped in a slim aluminum casing that looks at home sitting next to a MacBook. It’s expensive, but it works well with Mac or Windows, and the company’s espressoFlow software adds touch support when the monitor is connected, even to a Mac. In addition, Espresso Displays sells a stylus for taking notes on the touch display, and it offers a note-taking app called Jot on both Windows and Mac. The razor-thin monitor doesn’t have any physical mounting points; instead, it magnetically attaches to a foldable stand that adjusts in height and tilt, and you can rotate the display into any orientation. It also offers pass-through charging. However, our picks have better-looking displays, and we found the color controls on this model to be far too simple for us to adjust the picture appropriately. Our top pick from Arzopa offers the same resolution for far less, as well. Even so, the 15 Touch is an interesting option for Apple fans who are willing to pay more for an experience that’s designed to work seamlessly with their MacBook.
If you want a slimmer, smaller, higher-resolution touchscreen: We really liked the Lenovo M14t Gen 2 , which is a 14-inch touchscreen portable monitor with a 2240×1400 resolution. It has a similar-looking resolution and the same touch responsiveness as our larger 16-inch pick, but it’s much thinner and more portable. It’s also more expensive, at $400, but if you travel with the monitor often and want touch on Windows, this is the more convenient option.
What to look forward to
At CES 2025, we saw a handful of new portable monitors that we’re excited to test this year.
Arzopa, which makes our current top pick, showed off two new products: a 13-inch OLED portable monitor and a stacked dual-screen portable monitor. OLED monitors typically look better than their IPS counterparts, because they can individually turn off pixels to create truly black tones. But since the pixels are creating all the light themselves, we’ve found that cheaper or more budget-oriented OLEDs can be too dim for typical use, or sometimes have strange color casts. Arzopa doesn’t have much information available yet on those two new monitors, but we’re also interested in testing the 16-inch, 1440p Z1RC released late last year.
We also saw the Xebec Snap , screen extenders that are similar to (but seem better than) the clip-on laptop screen extenders that we mention below, but don’t recommend. Instead of clipping two monitors to the top of your laptop at the same time, you can clip a dock with magnetic attachment points onto your laptop. The dock has two pads that flip out from behind your laptop that let you magnetically attach up to two displays, or a display and accessories like a MagSafe mount for your phone. Other accessories allow you to put one display above your primary laptop screen, too, which we think is more comfortable ergonomically. It’s a very expensive system, starting at $550 for the magnetic dock and one display, but it’s unique and worth testing.
Australian company Espresso Display has two new monitors that we’ll be testing, the Espresso Display 15 and Espresso Display 15 Pro . The Display 15 costs $300, which is about $150 cheaper than the previous touch-enabled version, and is available now. It also has an option to come with a taller stand that raises the monitor above most laptop screens. The Display 15 Pro is more expensive, but it has a 4K resolution, full touch capabilities even on Mac, and is thinner and lighter than the previous 15-inch touch version. It costs $800, and is also on sale now.
What about a dual-screen, clip-on portable monitor?
We’ve seen many versions of a portable monitor that clips onto the back of your laptop’s screen and adds two smaller displays, one on each side. These monitors typically use two USB-C cables to connect the monitors to your laptop, which basically takes up most of a laptop’s available ports. They are also bulky to carry around and don’t have great specs.
We bought one on Amazon, the Kefeya Laptop Screen Extender , which has a design that seems to be copied or resold under different brands. The screen extender’s two displays each fared very poorly when put under the same tests we apply to all portable monitors. The screens only reached about 140 nits of brightness, which is about half as bright as we’d typically recommend. They also had lower contrast than we recommend, measuring about 820:1. Finally, we expect monitors to cover all of the sRGB color space, so you can see the same standard colors that video editors and web designers intend. But we found the screen could only show 78% of the sRGB color space.
We’re also unconvinced by the ergonomics of the double-screen laptop extender. Due to the weight of the two screens, your laptop screen needs to be tilted slightly backward so the kickstand can help support it. When the screen is tilted back like that, the straight hinges of the monitors cause them to angle upwards, which means you have to twist and tilt your neck—that is, unless they are pushed entirely flat and sit flush with your laptop’s screen. But when they’re pushed entirely flat, your laptop takes up more than three times the space than it originally did. We cannot in good conscience recommend subpar displays that jeopardize the already insufficient shared table space at coffee shops around the world.
What about a tablet?
Both iPads and Android tablets have gotten better in recent years at doubling as a second monitor. But unless you already have a tablet, we think that most people seeking a second screen should just buy a portable monitor, as they are less expensive and work better as a second display than any tablet we’ve tested. Portable monitors provide a simple, one-wire connection to your laptop or PC and have larger, 15- to 16-inch screens (versus the 10- and 13-inch screens of iPad models). On top of that, you never have to worry about a software update or a dead battery somehow interfering with your use of the device as a second monitor.
However, if you already own an iPad or want to mostly do iPad things and occasionally use the tablet as a second screen, it’s entirely doable. iPad models released in 2018 and later are compatible with Apple’s second-screen software, Sidecar , which is a simple-to-use feature with no latency. To connect iPads to Windows PCs or laptops, Wirecutter senior staff writer Joel Santo Domingo has used software like Duet for years and stands by it as an option.
We also tested Android functionality using a Samsung Galaxy Tab S9 Ultra, an also-great pick in our guide to pro tablets . We used the Galaxy Tab S9 Ultra as a second display for a desktop PC connected wirelessly over Wi-Fi. Our first connection produced a result so horribly artifacted that it looked a little like an alien transmission, but when we disconnected and reconnected the Galaxy Tab S9 Ultra, the second-screen function worked correctly and with almost no latency. The Galaxy Tab S9 Ultra might be one of the very few tablets we would recommend for use as a second screen, since it has a 14.6-inch display, larger than what you can get from most other tablets. However, the Galaxy Tab S9 Ultra starts at $1,050, and we truly do not recommend spending more than a thousand dollars to solve a problem that a $100 portable monitor can solve.
Why do portable monitors look blurry with Macs?
While testing both portable and desk-based monitors, we found that some lower-resolution displays looked significantly worse when used with Macs versus Windows laptops and PCs. After some research and testing, we’ve concluded that this has to do with the fact that all Mac displays use Apple’s Retina technology.
Mac computers tailor the image they send to an Apple-certified monitor with a process called display scaling. This process is meant to create a sharp, properly sized image, no matter the size of the display. However, newer Macs running on Apple’s M1 and M2 chips seem to have difficulty scaling for lower-resolution displays, and in our tests they ended up producing results that looked worse than we expected. The effect was most noticeable when we used a portable monitor with a Mac running the older macOS Monterey, and although that blurriness improved on Macs running a later macOS version, Ventura, the operating system’s settings made it difficult for us to get a sharp, properly scaled image.
We reached out to Apple about this issue, but the company didn’t offer a response. However, this effect has been reduced in the past few versions of macOS, and our current top pick and upgrade pick work well on both Mac and Windows.
If you’re befuddled by a blurry monitor, note that we were able to find and test one workaround for this problem, a macOS software utility called BetterDisplay. It essentially creates a fake monitor, called a dummy, that your Mac perceives as a shiny, expensive high-resolution display. The Mac then sends its scaled-up version of the picture to the dummy, which passes it to your portable monitor, where the image looks far sharper than before. The setup process takes a minute or two, but afterward it configures automatically every time you plug in the display. For ongoing use, you need to buy BetterDisplay for $19, but if you want to try it out first, the developer offers a two-week demo with all features enabled.
The competition
The ViewSonic VG1656-2K is similar to our best touchscreen pick, but without the touchscreen. It has good color accuracy and hit 396 nits of brightness, the brightest portable monitor we saw in this round of testing. But at $300 we don’t think the 2K resolution is a big enough jump for most people to warrant paying more than twice the price of our top pick. If you know you want the extra resolution for better scaling, it’s a great monitor, but it’s a bit more expensive than we’d like.
The Pluggable USB-C Portable Monitor looked OK when we first powered it up, but tested poorly in terms of contrast and color accuracy. We repeatedly measured the contrast of the unit we tested around 460:1, which is well below our threshold of 1000:1 for an IPS display. It supports a higher rate of pass-through charging than our picks, with 100W of power that it can funnel into a connected laptop, and it adds an extra USB-C port with up to 10 Gbps of data throughput. These could be useful features, but they didn’t make up for the poor image quality compared with the competition.
The Espresso Displays 15 unit that we were sent by the company for review had an issue that caused the screen to go black when connected to an input source, unless power was connected through the second USB-C port. Espresso told us this was an issue with the firmware update that specifically affected review units, but we can’t recommend the monitor until we’ve tested another copy successfully ourselves.
We tested two portable monitors by Ricoh, the 150 and 150BW . These are both 15.6-inch, 1080p touchscreen OLED displays, and the 150BW can receive wireless video over Wi-Fi from a Windows computer. They’re very slim, and both have a svelte kickstand that flips out of the back of the back of the display. This all sounds great, but the Ricoh 150 typically costs $550 and the Ricoh 150BW typically costs $850. This is much too expensive for a portable monitor, and we’d want to see these features cost closer to $400 to be realistically competitive.
The AOC 16T3EA had an issue in which its contrast ratio would drop when we turned it up to full brightness, a problem we’ve seen before in budget monitors. Its stand was also a bit limiting, and we preferred the look of other portable monitors.
We bought the Arzopa S1 Table but were unable to test it because it emitted a high-pitched whine when we powered it on, an issue that we saw a few other buyers report in online reviews. Arzopa accepted the return and replaced the unit in about three weeks, and the replacement didn’t have the same issue. We still think our top pick is a better monitor due to its kickstand, and a Wirecutter staffer long-term testing the replacement unit independently shared that they were a bit confused by the case stand at first and it had, rarely, collapsed when bumped.
The Arzopa Z1C is similar to our top pick, the Z1FC, except it doesn’t have a 144 Hz refresh rate for smoother motion. The Z1C unit we tested was much less color-accurate than the Z1FC, and we also thought the Z1FC’s picture looked better.
The Asus ZenScreen MB166CR is a lower-cost portable monitor in Asus’s line. However, its gimmick is a screw-on kickstand that is truly annoying to use. Adjusting the kickstand loosens it, which means you have to tighten the screw—but twisting the screw tight causes friction that changes the stand’s position. Life is too short to spend any amount of time fiddling with this stand.
Meant for creative pros, the Espresso Displays 17 Pro is a 17-inch, touchscreen, 4K portable monitor. Our testing showed that it could produce 97% of the colors in the DCI-P3 gamut, which makes it great for creative work. It also provides touchscreen and stylus functionality when connected to a Mac, features that you’d typically have to pay hundreds or thousands more for in a pen display such as those made by Wacom. We like this monitor on paper, but when we tested it, we found it to be too bulky and heavy to carry around comfortably—the Pro Stand made for the 17 Pro weighs 1.8 pounds, bringing the full portable setup to more than 4 pounds, not including your laptop or charging bricks. The monitor also has no physical buttons, so you need to use the espressoFlow software to change any settings, and we found the color settings in the app too limited for us to quickly fine-tune the display.
The ViewSonic VX1655 wasn’t as sharp as the other monitors we tested, and when we put it in sRGB mode to test its color accuracy, its contrast dropped to about 630:1. Other budget monitors offer a better experience.
The ViewSonic VX1655-4K is a competitive 4K display that we would have named our upgrade pick—but the OLED version is better. The VX1655-4K is color-accurate and bright, reaching nearly 500 nits. We recommend the OLED version because it gets even brighter, and OLED screens generally look better due to their increased contrast. But if you don’t like the glossy screen coating of the OLED model, the VX1655-4K is a worthy portable monitor to get instead.
The HP E14 G4 is a solid portable monitor with a 14-inch, 1080p display, a sturdy stand, and a basic on-screen menu for changing brightness, contrast, and color. But it’s smaller and much more expensive than our top pick, and it offers about the same image quality.
The Dell C1422H is extremely similar to HP’s E14 G4 in size and image quality, but it has fewer image settings. It’s a few years old, and you can get a better picture for much less money.
The Lenovo ThinkVision M14d is a 14-inch display with an impressive 2240×1400 resolution. It’s a nice monitor, but its $475 price tag at the time of our review was simply too high for that resolution and the monitor’s IPS display technology.
We also tested the Asus ZenScreen Go MB16AWP , a higher-end display with wireless connectivity and its own internal battery. This model has the ability to connect to your phone to act as a larger screen for you to watch TV or movies. However, when testing the wireless features, we found that many popular streaming services limit how their videos are viewed, which includes streaming video locally to another wireless device nearby. Although we were able to successfully stream video through Plex, the video was choppy and unwatchable. The wireless communication worked well for adding a second wireless display to Windows computers, though, so if you have that specific need, this monitor could be a good option. Overall, however, paying a premium for the battery and the wireless features of the MB16AWP doesn’t seem worth it given its restrictions.
