For gnome, and Plasma , in windows 11 its fine on the 4k 3840 x 2160 Scale but in linux it sometimes have to be changed as text stuff can look too small in the web browsers at that size and become unreadable to my eyes? it seems like plasma does handle 4k better than gnome for some text browser stuff, and budgie doesn't look great in 4k at all. the icons and its startup menu is very small taskbar under 4k in budgie, its not scaled right by default for a 4k display.
For me, in the firefox or google chrome or other browsers, I find that I have to go into display and turn the scale up say to 150 about or so, in windows 11 the text in my browser is readable, but for whatever when linux and its shells like plasma and gnome, they don't always look good with text the images are fine for me, but I find myself having to adjust stuff for my M28U monitor, linux sometimes has font sizes too small, and makes stuff unreadable I noticed that since getting a 4k monitor, it was never a problem with my old 1080 monitor but I am not using that one anymore.
Do you think that Solus 5 will have better monitor support or DEs like a make for 4k Plasma desktop setup, or by default have better 4k Gnome setup for reading text without having to scale it up under linux, again this was never a problem for me when I used a 1080 monitor, and I didn't know that the Desktops in linux wouldn't like 4k monitors, it seems like have not found a great 4k distro yet based on linux that can be used, for me Plasma handles the 4k monitor text problem better than gnome does, sometimes when the display settings are changed in gnome it doesn't always handle it well based on which distro I had tried anyway else had any problems related to using linux with 4k monitors also it supports HDR on under windows, but I don't really see any HDR options under linux yet, I haven't fully look at the offical settings for nvidia in linux, but I am pretty sure linux doesn't show any HDR options yet for current linux versions, I don't know about future linux if that will include HDR options for linux desktops and video playback or not, or for the video games under linux, I don't know if any of them even support HDR in linux games yet?
