I actually DO suspect the display. Could be handshaking.. could be a number of things. Without make and model numbers, however, I can't really help you. Have you tried the same computer on a different brand of display? Especially one that is NOT a 4k display. Just a suggestion.

Sorry to read about your problem, Al141.
Thank you for posting your comments and bringing your concerns to the attention of the community. Allow me to express how sorry I am that you encountered difficulties in attempting to resolve your concerns. I can only imagine your frustration. I do not work for Lenovo. This is a peer to peer forum provided by Lenovo so that members may share their experiences and help each other. I am a customer like you and a volunteer on the forum. There is a Lenovo presence here who deal with some of the broader issues, but unfortunately because of the number of queries there is no guarantee you will receive a direct response.
Perhaps you could contact Lenovo again and request that the agent escalate the case on your behalf; they will then be able to explain the process.

Still don't know your model numbers. Computer and displays. I use a trendnet adapter with a 910 and 920 on a 5-year old Vizio. Works fine.
