I have a decent GPU, thats why I am now looking for a screen to make use of it.
Some 4K video is stunning makes HD look like SD
I would sell my soul for a 32 inch O.L.E.D gaming monitor although it would have to be under a grand (low rent sinner). I got one of the latest Sony O.L.E.D's for the living room, never seen one before, I could not believe my eyes when I turned it on. Did not expect it to be as good as it is.
4k blue ray, something like Bladerunner, moments when it takes your breath away, see detail never seen before. Also upscales really well, so not much of a difference between upscaled Netflix content and 4k online content.
To get that clarity and contrast on a gaming monitor, happen sometime, can't come soon enough.
But yes 4k movies awesome, 2001 a space odyssey tomorrow night, can't wait, in 4k I think its going to be good.
