Haven't we already seen how it upscales?
What he is saying is that not all upscaling is created equal.
Most HDTVs just stretch the image to fit the screen using a hardware scaler, basically formatting to fit the screen properly.
Mid-high end tvs actually have an upscaler that can duplicated or mirror surrounding pixels. This actually adds some pixels to the image so it is sharper than just stretching the image.
PS4 Pro takes a very different method called checkerboard rendering. Basically the PS4 pro renders the equivalent of a 1440p image in a checkerboard pattern and using an algorith, the scaler reads the pixels and fills in the missing pixels. This is a higher quality method because it is done in rendering and not by the tv or a scaler. It looks more natural and gives the illusion of true 4k rather than just a stretched or replicated pixels which creates blur and ghosting.
Gee thanks. lol
We've all seen how it upscales, and it's not worth $400 when basically every tv on the market will do something similar. Thanks for playing. Next!
No, there is not a TV on the market that renders a game.
Doing it in rendering BEFORE you get the final image on your TV provides a much clearer, higher quality image and allows devs, if they wanted to, to add post process filters to mitigate any blur, ghosting, or aliasing.
TVs just stretch or duplicates pixels, blurring the image either way.
4K upscaling and checkerboard 4k are very different.
PS4 Pros method is just called upscaling because the average consumer wont understand or is patient enough to listen to an explanation.
In actuality it is MUCH different than traditional upscaling methods.
This is why it was at GDC, it was a big deal, a big breakthrough.
