Title: Dell S3222DGM Monitor and Intel Xe Graphics doesn't work above 1280x800@60hz in kernel 6.2.0 (but 6.4.6 works) Status in linux-hwe-6.2 package in Ubuntu: New Bug description: Ubuntu 22.04.3 LTS, Dell S3222DGM, Intel Xe Graphics Dell Monitor on a laptop with Mesa Intel Xe Graphics running Ubuntu kernels doesn't work in higher resolutions than 1280x800@60hz. At that resolution the screen goes black and then displays "No HDMI signal from your device" for a while before shutting down into powersaving mode. 1280x768@60hz also works, while 1280x768@120hz does not. Observed with both Ubuntu 6.2.0 and 5.19.0 kernels. Changing to a mainline kernel resolves this completely, I've tried 6.4.6 which works perfectly at all resolutions listed in settings. I've tried with two other monitors I have which do not exhibit this problem. I've tried the Dell monitor with several other computers and verified that it does not exhibit this problem with them.
