All my gaming is on my LG 1440p ultrawide. If a game doesn't support 3440 x 1440 I find mods that will do it.

Then I have a couple other monitors in 1080p for windows / apps and streaming services (Youtube / Twitch / etc).

Things can be sluggish if I'm 5 boxing retail and watching a stream. So I offload that work sometimes to a PS4.
