I’m dual booting Pop_OS and Windows 11 for now while l try things out. I went with Pop_OS for the NVIDIA drivers, since I have a NVIDIA card. Installation went smoothly, but setup is where things started to get a little weird.

I have 2 monitors, a main 360hz monitor and a secondary 165hz monitor. I seem to be able to have them both working at the same time in Windows 11 without issue, but in Pop_OS, setting the refresh rate to 360hz on the first monitor causes both displays to stop working properly. The 360hz monitor will stop displaying picture all-together, and the 165hz monitor will start flickering wildly. Turning off the second monitor brings the 360hz’s image back, but then I’m down a monitor. Also, if I set the refresh rate to anything lower than 360hz, they’ll both work. I’d like to still be able to use it at the native refresh rate, but I can’t seem to find any other solutions or anyone else who seems to have had this same issue.

My second (slightly less annoying) issue is that I can’t seem to use HDR in games. Is this normal, or is there something I can do to bring back support?

Also, if Pop_OS isn’t the way to go, please let me know! I tried Nobara first, but immediately had issues with the displays locking up and flickering before I even got it installed.

    Someone correct me if I’m wrong but if you’re using stock Pop_OS it uses xorg by default as the compositor which iirc has issues with multiple monitors on different refresh rates. You can edit your .config file to enable the Wayland compositor and give it a try and see if it works!

      Correct, here’s a guide to enabling Wayland.

      I’ve never had OP’s problem, but another avenue I’d consider is to set display settings in the nvidia-settings app, which can be opened with a GUI from the terminal. These settings are separate from those in the normal settings menu, in ways I don’t totally understand.
