I use an 48 OLED mainly for console gaming and a 38 for PC gaming. I sometimes use the 48 OLED for pc gaming but find the 4k resolution a bit restrictive sometimes for some games. So best of both worlds here. Had a 43 Monitor and that was just too uncomfortable as a main screen.
Yeah, 43 I feel will be too big although we have a 43" TV in the bedroom I might nick for a bit and try out. 32" at 4K I wonder would it be too small at 100% scaling, at 125% or somthing I think I'd end up with less usable space than an UW at 1440P.
