Can 4K TVs make 'regular' HD content look better?
CNET.com asks: Can 4K TVs make ‘regular’ HD content look better?
If you listen to the marketing from TV manufacturers, it seems TVs with 4K resolution will deliver a massive boost in picture quality.
And, if you’re lucky enough to actually have a source of real 4K video — one with the same 3,840×2,160-pixel resolution as 4K TVs — you may well be able to see additional detail. (4K TVs — also known as Ultra HD sets — are so named because that 3,840-pixel horizontal resolution is almost 4,000 pixels wide. 4K TV is less of a mouthful than 3.84K TV.)
But real 4K video sources are still few and between, which means most of us will be watching content in good, old-fashioned “regular” high-def: 1,920×1,080 (1080i or 1080p) or 1,280×720 (720p), both of which have far fewer pixels than 4K.
Since that’ll be the case for many years to come, how much would a 4K TV actually improve the picture?
