In the computer world they use an incomprehensible and shockingly un-user-friendly jumble of letters to describe resolution. Well, not “shockingly” since these are computers.

Basically, the ones you’re most likely to see are FHD (1,920×1,080) and WUXGA (1,920×1,200). The rest, you can dive into and print yourself a cheat sheet from this.

Fortunately, the only time most of you will come across this letter goulash is if you’re looking for a cheap data projector or a computer monitor.

-Some Common FAQ’S

1) What is a 4k Ultra HD TV?

Ultra High-Definition (4K) video is the next big step in TV technology. Find out if now’s the time to upgrade. High definition has meant 1080p (1,920 by 1,080) resolution for years now, and it’s ready for an upgrade. That’s where ultra high-definition, or UHD, television comes in. You might have heard it called 4K.

2) Is UHD 4k?

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.

3) Do you need a special HDMI cable for 4k?

Most mid- and high-end TVs are now Ultra HD resolution, with many also supporting HDR. Not surprisingly, cable manufacturers are jumping at the chance to sell new and more expensive “4K” HDMI cables. But guess what — you probably don’t need 4K HDMI cables, because your current ones can likely do 4K just fine.

4) What is 4k on TV?

This is a TV with a resolution of 3,840 x 2,160 pixels, more than 8 million pixels in total, which is four times the number in Full HD (1,920 x 1,080). Watching 4K TV at its best, you’ll see everything on screen in crystal-clear clarity and sumptuous detail.

5) What is the resolution of 2160p?

2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p. The number 2160 stands for a display resolution which has 2160 pixels along the shortest side, while the letter p stands for progressive scan or non-interlaced.

6) What is a 8k TV?

8K resolution or 8K UHD is the current highest ultra high definition television (UHDTV) resolution in digital television and digital cinematography. 8K refers to the horizontal resolution in the order of 8,000 pixels, forming the total image dimensions of (7680×4320).


When you boil it all down, here’s the takeaway: Your current TV (unless it’s really new) is HD, either 720p or, more likely, 1080p. New 4K Ultra HD TVs have four times as many pixels as 1080p.

Here’s where we remind you that more pixels doesn’t necessarily mean a better picture. There are other aspects of picture quality, such as contrast and color, that are far more important than resolution. That said, if you’re buying a new midrange or high-end TV, it will probably be UHD anyway.
