Hello all,
It appears that my Lenovo yoga laptop no longer can output 4k video via USB C. When I attempt to change the resolution on the external monitor it is limited to 1920 x 1080. The intel graphics command center does show that the connected monitor is capable of 4k but the resolution settings only display options to 1080. This is a new problem, I have been running this external monitor at 4k for 6 months. I verified that the monitor setup is working correctly by using another laptop with Iris Xe and it worked fine. Here are all the steps I have tried.
- Windows up date
- Lenovo updates for video and bios
- Updated driver directly from intel
- Force installed 3 previous intel driver versions
- Completely uninstalled driver from windows and reinstalled
- Complete reinstall of Windows 11
I do from time to time get the following event in the logs but it isn't all the time and it seems to have started successfully recently.
Device PCI\VEN_8086&DEV_9A49&SUBSYS_3F1A17AA&REV_01\3&11583659&1&10 had a problem starting.

I am completely at a loss as to what to try next. Any ideas?
