I've been using a LG 27GR95QE for a couple of months now and I love it.
One of the issues with OLED monitors is sub-pixel rendering/layouts being different than usual LCD, which you can mostly bypass in Linux (I've been using it for work and am really not bothered after 8hrs/day looking at code).
Yeah it should just work as a regular display. I have a LG C2 42inch and I can drive it over HDMI 2.1 at 4k 120Hz with Nvidia 3090. Works really well and the display is beautiful.
I've been using an Asus vivobook with an oled screen for the past two months. It works perfectly fine, imo especially on Wayland with the proper scaling setting.
The only thing you should be aware of is that some apps still rely exclusively on X, and those will look blurry
Off topic, but what distro are you using? I have an Asus vivobook as well and neither the speakers, bluetooth, or touchpad gestures worked whenever I installed Zorin or PopOS. I don't have the time or knowledge to mess around with it so I just went back to Windows
Do you know if your OLED screen has a standard pixel layout or if it has one of the modified ones?
For example QD-OLED are structured in a triangle and some of the LG ones have 4 instead of 3 (if I'm recalling it correctly). The result on windows for both of these is a slightly more blurry text.
The blurriness comes from the (fractional) scaling mechanism use for X applications inside Wayland. Some time ago KDE enabled a mode that fixes blurriness (using the "native" X scaling).
