Quite stupid. We have 1920x1080 monitors for PC, where we have enough CPU and graphic power, and also enough energy. Why would somebody need a resolution higher that what he can see? Just to consume energy? To have higher lag? Higher resolution need higher CPU/GPU;

This is just marketing like 64bit ifone 5.

Only few GPUs can play games on more than 1080p resolution. And you need 150-200W power for that. that is for real games not angry birds. What is the point of having 3840x2160 resolution when the hardware cannot use it? Angry birds looks the same on 320x240 resolution.

I would take a 50" HD ready plasma over this display, for games and movies any day.

Being near sighted has some amazing advantages, which proven in animal kingdom as well, some animals are extremely near sighted because it benefits their way of living.

I would like to emphasise that it (i.e. the resolution of 4K or 2K) is a matter of the amount of pixels in the long side of screen, not in the area. In respect of the area of the screen the 4K resolution screen has 4 times more pixels than 2K resolution screen. It is confusing but it is true. Sorry about my english :)

Hahaha.Lolz.Good one!.Can somebody tell me,will there be ever a saturation point when coming to Display PPi.Instead,they must work on Flexible CPUs batteries and other flexible hardware and Augmented reality devices acting as Phone TV and Home theatre,just everything.

We have increased tech in all areas bar battery..This new silicon tech should give mobile gasdgets a much needed boost.

As for flexible screens I like the rolled up idea but only seen Philips do one in monochrome only.Then a smartfone can have a small screen to show all basic info then roll out for bigger screen for gaming/tv/web browsing.

At full power it uses 3.6 Watts that quite astonishing.

4K resolution is a generic term for display devices or content having horizontal resolution on the order of 4,000 pixels.

2-1920 * 2*1080 like you said would result in an 8k resolution.
Revise your math.
