It will work on high rez screens (I know because that is supported by KDE plasma). For color accurate work, you may have to wait until valve enables wayland on steam os or install windows on it. As for it's own screen, I am not the person you are looking for...
Maybe try a FrameWork laptop. Just as repairable (if not more) and is an actual laptop that can help you do your work. Again, I don't know if it could be color accurate enough for your work.
I guess TF2 is good fun...
Then old nintendo games...
CS when not taken too seriously/is an older version than GO...
TF|2 (Titanfall 2)
Halo custom games...
ect
I have and I do! In fact, I've been trying some old nintendo games (SM64, DKC mostly)... TF2 and TF|2 are ones that I play when comes to online that I enjoy (especially when I stumbled on a VSH lobby after the summer update where people were spamming the vc with memes and sound effects... It was awesome). CS:GO and L4D2 are the games that I mostly enjoy playing when there is company (yes I am the type of person that would preffer playing with a shotgun in Office)... Apex is the game we mostly play but I do it more because of the human interaction rather than because I enjoy it as a game. Oh there is also Halo that I enjoy mostly from the campaigns and the custom games.
Does this affect fdroid?
