Sony's New 4K Resolution Standard Demonstrated Using Gran Turismo 5

Is it actually rendering at 4k or is it just upscaled 480p or 720p like the ps3 does with other games? If so its not really 4k rendering sorry sony. Hook a high powered pc up to it.

I can tell the different on my TV. Probably because its a plasma. I can't stand watching anything under 1080p. Some Xbox 360 games that are just upscaled are a real eyesore (Silent Hill: Downpour was a really bad recent offender).

Not exactly coming to a home near you: Sony's website shows the 4k resolution TV as 84 inches, and $25,000. Also, this TV won't do much good without 4k resolution content, the likes of which isn't exactly falling from the skies.

I guess my advice is to start saving now, and by the time you can afford one, maybe it won't be so far ahead the curve that it is so limited in usefulness.

4k is the next step in TV tech, but I still think its going to be a few years until the price gets to a point where it can go mainstream. I would guess atleast another 5 years until 4k is affordable.

By the time we all have next-gen consoles, this'll be the norm. So about.....2-3 years.

Not sure how it will be for gaming but unless you're getting a ridiculously large screen, 4K is useless. There have been studies showing no difference noticeable between 720p and 1080p on a 50 inch T.V at a 10 foot viewing distance. Quadrupling that resolution will not produce a significantly sharper image unless we're talking 134 inches. So movie theaters or sitting really close. Where it would be beneficial is with passive 3D. Passive 3D basically cuts the resolution in half for each eye, harming the image quality. A 4K t.v with passive 3D would definitely remedy that. But yeah, for your standard user, I don't think we will see much difference. Plus it will be a few more years before the format becomes standard...
