Nvidia HDMI 1080p 120hz support
Hey folks I've recently gotten a few portable monitors to use with my setup, neither of them seem to work.
I only intend on using one display, but out of 3 of them only one works via HDMI at 1440p 120hz. Switching it down to 1080p fails to show an image.
The other two work at 1080p 60hz, but not 120hz using both HDMI ports on an RTX 3060.
Using a DP to HDMI adapter seems to work around this issue. Is it possible to not have to use the DP adapter?
Edit: The 1080p 120hz displays work without issue on a Windows 11 laptop via HDMI

I think I've faced this issue and it took me a long time to figure out
My problem was nvidia drivers, either not updated or using the open source ones nouvou
you can run
nvidia-smi to make sure the drivers are the latest (I think should be 560)
Also I find kde to be very unstable when it comes to resolution, I had displays that could not change to a good resolution at times but then sometimes they did? gnome generally worked for me
Also, 16:9 would generally work, other resolutions might not all show every resolution from what I've tried, I think there's a configuration file you can edit for thisLooks like I am on 560.35.03, and KDE as that was default
Same issue on Gnome.
Currently bypassing the issue with a DP to USB C cable to the portable monitor
Does it work with this adapter?
That's weird I'll be honest, but it might be the cable, is it 2.1? Is your GPU ports 2.1 too? I remember anything lower than that caps to 60 hz 1440p or 120 hz 1080p
Also to tell that you have to squint really hard on some label on the cable written near the tip😅
I've gotten the same port and cable work at 1080p 120hz with a different display and on a different machine
I would've just recommended you reinstall drivers and such but this is bazzite and it's not something you're meant to do in it
I do know that 560 is beta, perhaps the driver being too new is the problem I wonder
One more thing you could check and that's VRR and night mode and settings like these try to disable/enable it and try tyo disable one screen to check if you can change when there's onyl one connected, also maybe try connecting the displayport instead of the hdmi to the display that doesn't work
You're right that if the display works with 120 despite working with other systems it has to be something with linux but somehow one display does work which is weird, I would've expected none to work
Also maybe try playing with the monitor settings and see if anything there affects it? HDR is a big no currently because I know it might limit FPS so it might be that
For the time being I've worked around the issue with a DP to type C cable. 1080p120 works as intended
