I currently have a dual monitor setup of a Dell 24" and 27", neither are variable refresh rate. I think the 24" monitor is getting on for 17 years old and has had issues with lines on it when cold for the past 13 years. But it’s my second monitor and once it’s warmed up it’s not too bad. Well I think the time has come to retire it and for my main 27" to become my secondary monitor and buy a new primary. I am interested in photography so accurate colours are important to me, which is why I bought these monitors in the first place. But I also play games, so something with some gaming features like Freesync and >60Hz refresh rates I also want. I’ve got my eye on a ASUS ROG Strix XG27ACS, fwiw.
I am running Endeavour OS (kernel 6.13.1) with KDE Plasma (6.2.5) on Wayland with a Radeon RX 5700 XT. My question is: Will my setup allow me to run one non-freesync monitor @60Hz and one Freesync monitor using the VRR at up to 180Hz. So I can get all the benefits of the new monitor when gaming, without having to turn the second monitor off?
I believe that if I just had the one monitor I’d have no issues and my setup would be plug and play. But as this has been a long time coming with many issues along the way to get VRR on linux working, I’m concerned that it’s a “everything must support it or it won’t work” scenario.
Grateful for your insights and advise.
From my experience your mileage may vary when it comes to being able to keep both monitors on. The concept of a primary monitor on wayland doesn’t exist, and my games always choose the wrong monitor to render on. The game will open on my primary monitor but i can only select the resolution and refreshrate of my secondary monitor in the game settings. If you have identical monitors that would probably not be an issue, but i don’t. Setting the primary xwayland display with xrandr helps for some games, but not all. The best solution for me ended up being to disable my secondary monitor when gaming.
Thankfully I’ve not had that issue. It knows which is the main one and picks the right resolution even though one is 1440 and one 1200. Moving to 2x 1440 monitors should hopefully simplify things in that regard
