My only concern is video smoothness and ease of use, I don't care about colour accuracy for instance.
I spend most of my time in front of my computer so I think oled is not an option.
My main use is to watch movies and series from torrents, also a lot of youtube videos. I just hate tearing, frame dropping, bad blur, I get them too often (although I'm paying less attention lately), and I get motion sick easily when the videos I watch were shot with quick or even slow pannings from left to right /right to left.
I never play any game.
I do some video editing, always at 24 images per second.
Right now I use two monitors :
-Overclocked (@96hz) Qnix 2710 1440p 27"
-22"(or maybe 21") CRT monitor "Iiyama Vison Master Pro514 HM204DT A" I'm using it at 2048*1536 resolution and 85hz.
I use the CRT at high brightness for videos because it seems there's less tearing, but maybe it's only because the monitor is smaller (also less tearing doesn't mean none), and I use the Qnix 2710 1440p 27" at low brightness for everything else because it's sharp and large.
I'm on windows 7 with a HD7850 graphic card, I'm planning on using Linux if I buy a new computer.
