It was running fine at 4K@60Hz until couple days ago when it switched to 1080p and I cannot convince it to go back. When laptop is booting TV shows DELL logo at 4K@60Hz but as soon as Windows 11 boots up it goes back to 1080p.
CRU shows that detailed 4K@60Hz resolution is there but I don't see it in the list of available resolutions in Setting. Restarts doesn't help. Any ideas?
Update: If I uninstall Intel Driver, reboot, Windows uses Microsoft Basic Adapter and the only available resolution is 4K@60Hz but as soon as I reinstall driver 4K is gone and only 1080p is available. What's going on?

3840x2160 @ 60 Hz only requires HDMI 2.0, so either something is wrong with the cable or adapter that is causing the graphics driver to drop down to HDMI 1.x, or there's an issue with Intel's driver.
