Native 4K or Checkerboard "uprendered" 4k

The image is originally rendered with half the resolution of 4k. Then they fill the missing dots with their patented mathematical algorithm *cough* marketing bollocks *cough* to upscale the image on a 4k TV / Monitor. An upscalled image always tends to appear blurry.

It's one thing to be spitting marketing BS, it's another thing to customize a GPU and add components to it that allows the GPU do a specific task that GPUs typically don't have the hardware to do and patent the tech. 

And there is no doubt that an upscaled image is always gonna be blurrier than a native image. But the point is this;

It's one thing to upscale from 1080p yo 4k (that's making up for 6M absent pixels), it's another thing to upscale from 2*1080p to 4k. In that case you only have to account for 4M pixels. If the results are such that you have to freeze frame and zoom in to spot differences isn't that at the very least somewhat commendable?

And look at XB1 to PS4, 900p to 1080p.... it's already hard enough telling them apart as it is. When looking at 4k and faux4k it's gonna be even harder. 

To customize the GPU and adding components is for the sole purpose of lowering the necessary resources to upscale the image. Nothing more.

That so called "checkerboard" algorithm is Sony's research of accomplishing the "probably" best image quality by upscaling it while only rendering with half the resolution of 4k.

An upscaled 4k image from whatever resolution is still not true 4k. But that's probably nothing anybody is argumenting for.

The link only describes the process of upscaling. Being 1080p on that site doesn't make the argument less appealing.

If you don't see the difference, well, good for you I guess? Some people do and they see the blurry screen as I do. The game is still being rendered only with half the resolution of 4k. You can upscale and try all the magic you can come up with to make the picture look nices and fill the empty dots with made up informations. But the result is still a lower rendered image with doesn't come close to 4k.

So far as I heard, there will be games on the PS4pro which will be rendered at native 4k. But this will be material for another discussion.
