4k maybe on ps5
Frankly 4K isn't practical yet, but I imagine 4K will be widely in use by Christmas 2015.
I have a 4k monitor but right now there isn't really any reason to game on it.
What do you do with it then?
Normal computer stuff. I like the screen real estate over 1080p. It's really useful for programming also. The input lag is also a lot more noticeable on 4K right now so it isn't optimal for shooters.
Do you think it is because of the gpu or because of lack of 4k support?
Not so much the support but it's hard to change ~10 million pixels in a few milliseconds. More expensive 4K screen might be better though.
End of the year? Just depends i personally havent seen a 4k tv of reasonable size under 1000$ plus i feel 4k will need more purposes than gaming before wide mainstream acceptance
A lot can change in a year.
I know but i feel cost needs to go down beford wide mainstream adoption which i doubt will happen this year but i can happen.....
