Well my monitors are so old they don't even have LED back lights.
Isn't 2K the same as 1080P? I think 1080P is fine for what I do most of the time, which is read the internet, watch videos, and casually game.
I'm considering this, the cheapest ultrasharp. I'm assuming 6ms is enough for casual gaming. Also the small edge will be really nice for butting two monitors next to each other as I currently have an inch and a half gap screen edge to screen edge.
