As I have been trying to explain to people in the thread that "4K" is probably a misunderstanding... what they must mean is UHD (anything above 1080p but not necessarily 4k.

There is nothing in between for TVs. It's 1080p or 4k.

Difference between Ultra HD and 4K

Technically, "Ultra High Definition" is actually a derivation of the 4K digital cinema standard. However while your local multiplex shows images in native 4096 x 2160 4K resolution, the new Ultra HD consumer format has a slightly lower resolution of 3840 X 2160.

This is one reason why some brands prefer not to use the 4K label at all, sticking with Ultra HD or UHD instead. However, the numerical shorthand looks likely to stick. As a broad brush label it's so much snappier!

 

Just because the TV displays at UHD levels doesnt mean that the PS4.5 cant upscale from a resolution somewhere inbetween.
