Windows 10: Unable to output 4k resolution potentially after recent update.

A colleague and I have been using 4k external monitors with our windows 11 dell laptops for the last month, for which we've been able to set the correct resolution. However, at some point in the last week we've both lost the ability to set any resolution above 1080p for the external monitors.I've tried the following:A different hdmi cable.A different hdmi port.Updating the graphics drivers.Installing older graphics drivers.Rolling back what windows 11 updates I could very limited.Resetting windows 11.Reinstalling windows 11.Does anyone have any other suggestions of things to try?

After the recent update, I have no idea why the resolution has change from 4k to 640 x 480 resolution. I have uninstall the intel 530 graphics diver and reinstall it, the problem still exist.

 

Can't output in 3440x1440 resolution

Hello,

My work computer has an integrated Intel HD Graphics 620 and should be able to output 3440x1440 resolution. I've updated all the drivers, and even installed a monitor driver.

My work computer here has HDMI and DisplayPort output, though the DisplayPort is damaged. I tried that connection at first, and found 3440x1440 as on option over the faulty DisplayPort, but not HDMI. I need 3440x1440 over HDMI, this should be possible.

Right now the monitor defaults to 3840x2160 (4K) on HDMI which is totally incorrect, and warped. What else can I do?
