My displays seems to be rendering at 1080p (settings page confirms this), but my display is 4k, but that isn't an option in the displays settings, page the highest it goes is 1080p for some reason. I found a similar questions suggestions to install mesa-utils, did that and restarted but the right options still aren't there. See attached screenshot. Any help is appreciated!

Edit: Added sudo lshw -c video output below:

emily@EmilysElementaryOSLinuxBox:~$ sudo lshw -c video

  • This can sometimes be an issue with the video card not using the correct driver. Cold you edit your question to include the Terminal output of sudo lshw -c video? Have you also tried changing the Scaling Factor from LoDPI to HiDPI to see if the higher resolutions are available? 🤔

  • Is it a laptop or an external monitor? If external, maybe check if the cable is capable of that.

  • It's an external display and a dedicated mini PC, hadn't thought to check cable... let me check. I know with my windows PC on same monitor it shows 4k/60 with a standard/cheap HDMI cable. I will say the mini PC has a display port only so I have a display port to hdmi adapter inline, maybe that's causing issues. Let me tinker with cables a bit and see what I can find.

Happy to report that getting a dedicated display port to display port cable and hooking directly up from the mini PC to the monitor resolved this issue and it was immediately recognized as 4K. So seems something with that display port to HDMI adapter wasn't allowing the OS or display driver or something to recognized the true resolution.

So TLDR = yeah just avoid display connection adapters and hopefully you won't also have this issue. :)
