I use an HDTV and an HDR 2k165hz monitor. I set the desktop background to black, anything else messes with my peripheral vision if some window decoration isn't aligned with the background.
I also use a 720p60 projector as a screen sometimes on that machine, too.
It all just works. My largest complaint with Windows seems to have been fixed with the 24h2 patch - read on if you care.
I use "@" prefixes on folder names to have them sort first when sorting by name descending. Somehow for a couple years, some applications would crash if trying to stat these folders, for example, launching VLC would usually crash it if the last thing I played was something from V:\@TV\Columbo
I was keeping a list of things that crashed like this; or while opening or saving files in "@" folders. Notepad, notepad++, vlc, mplayer, windows photo viewer (any and all), and so on
I was able to guess it had something to do with internal variables in the windows API, you can see them on my system in pwsh by going to V: \ and typing @ and pressing tab key. They're even a different color than the quoted folder name that eventually appears.
I could never figure out how to report this bug in a way that would be helpful, as I barely use powershell or the windows API.
