I possess a lg 34" (the curved one), you can run it just fine with intel integrated graphics (my processor is a i7 4790k) if you don't use display heavy applications (like games).
You can also play very well with a dedicated graphic card and a gaming virtual machine (using vga passthrough and something like a gtx 980ti to run games well), in case you change your mind about gaming someday.
Biggest downside i found was that it was impossible for me to see my bios menu with this screen, i have no idea if this is grub related since i purchased the screen for my gaming vm, easily fix with a second screen which i use only for my fedora host.
Anyway, since you won't play, if you can find the reason of the issue i got and fix it you won't have any problem at all. You won't even need to install a specific driver.
