I'm looking to get an Onkyo or Integra A/V receiver and I noticed they have "4k upscaling" [3840 x 2160 or 4096 x 2160] which is something other receiver companies do not have [yet?]. They have the Marvell Kyoto G2H chip. I've been reading around and I'm trying to clarify some of the things I've read. Although the chip is able "guess" the missing information to upscale the resolution to 4k, does it make a difference if your tv's max resolution is 1080? Would this technology be used mostly for projectors or can it be used for tv's too?

4K upscaling means taking the native resolution of your source (be it standard definition or one of the many high definition formats such as 1080i) and upscaling it to a full resolution of 3,840 x 2,160 pixels. Bearing in mind that 1080p (the usual maximum resolution) is only 1,920 x 1,080 pixels. you can see that 4K upscaling is four TIMES the resolution.
This is an impressively large resolution, but will it mean a better picture? Well, the thing to bear in mind here is source and screen. If your source is 1080p, then the final image, even upscaled, is still based on a 1080p source - you cannot add additional information. However, with a good quality video processing chip, you can 'guess' the missing information, so theoretically yes - you can improve the picture.
However, more important is your screen. Most televisions will reach a maximum of 1080p as that is the current standard, and whilst some projectors may be able to reach these heady heights, it's not the norm. Therefore, 4K upscaling will do pretty much nothing in these instances. It's best to output to the native resolution of your screen, so check your screens resolution and choose the right format for your screen - of course, the Onkyo will let you do that!
