My dude, It's been more than capable for years. I have an ultrawide OLED monitor (3440x1440@165hz) paired with a 4K@144hz monitor. Both HDR, different capabilities. Both have different DPIs set, 125% for one, 200% for the other. My setup required less configuration than Windows does. Right click -> Display Configuration -> Set Alignment (monitor position) -> Set refresh rate -> Set HDR -> Set DPI -> Apply. Done.

Don't knock it unless you've tried it.

This was CachyOS btw. Windows actually required MORE work because I had to install drivers, connect to the internet during setup, get nagged about using a Microsoft account, etc.

CachyOS was basically boot -> verify partitions are correct -> decide on defaults -> create account/password -> wait for files to copy -> done. Drivers, including the latest NVIDIA drivers, auto installed/working.

Tried 3 months ago with Gnome (PopOS) and a 4k screen at 125% scaling, apps were blurry, especially Brave, which was a big disappointment.

I give Linux a try each time I need to set up a new computer, and each time run into new issues. Last time (2 years ago) the hdmi connection with the screen would drop randomly twice a day. Same for the keyboard, and the wifi card didn't have drivers available. It became quite annoying, reducing my productivity as I had to reboot and pray. I then installed Windows, which solved all of the issues (unfortunately?)

Maybe I'm just unlucky.
