I’ve had difficulty with Thunderbolt 4 connections flaking out. I’m connecting a Lenovo Thinkpad to a Lenovo dock and the connection is sensitive to being looked at. Touching the cable on the PC side tends to disconnect it. I’ve tried both ports (and even different laptops).
I suspect the cable. Any suggestions for high quality Thunderbolt 4 cables? And ones that are certified for 100W charging?
Within reason, price not important.
