Ultra HD TVs aren't technically "4K" since their resolution is 3,840x2,160. However, it doesn't matter. 4K is way easier to say than 2,160p or Ultra HD, and when anyone runs a survey asking about it, the vast majority of you (and us, FWIW), greatly prefer "4K." So do Google.

1080p or Full HD Nearly all HDTVs have an aspect ratio of 1.78:1 (16:9, aka "widescreen"), so that means a horizontal resolution of 1,920 pixels (1,920x1,080). ... That said, most people don't call 1080p 2K; they call it 1080p or Full HD. By the way, 1080i is the same resolution as 1080p, but no modern TV is 1080i.

2K, however, is supposed to have somewhere around 2000 pixels (the K stands for kilo meaning "times 1000"). The 2K, 4K and 8K terms are more generic than QHD, UHD (3840 pixels × 2160) and FUHD (7680 × 4320). ... So QHD is part of 2K, but it is not the same (a 2048p resolution is 2K, but not QHD).

1080p though can hurt at higher screen sizes, which is why I highly recommend 2K. Also consider that most high end systems can do 144 FPS at 2K for most games on ultra. In general, yes you can gain a lot by increasing your resolution to 2K and I recommend it highly. ... 27″ and 2′ viewing distance is definitely worth 2K.

4K Ultra HD A 4K TV has an even higher resolution than an HDTV.

A 4K TV's resolution is 3840×2160, or 4 times the resolution of full HD.

For example, an image that is 2048 pixels wide and 1536 pixels high (2048 x 1536) contains (multiply) 3,145,728 pixels (or 3.1 Megapixels).

4K resolution, at least the way most TVs define it, is 3840 x 2160 or 2160p. To put that in perspective, a full HD 1080p image is only a 1920x1080 resolution. 4K screens have about 8 million pixels, which is around four times what your current 1080p set can display.
