LG Ultra Definition TV
Suddenly we will forget about HD and 1080p, anew quality standard is emerging for Tv’s ultra resolution, 4K and 8K.

4K and 8K are an emerging standard for resolution in digital film and computer graphics. The name is derived from the horizontal resolution, which is approximately 4,000 and 8,000 pixels. This designation is different to the standard resolution designations which are represented by the vertical pixel count; for example 720p and 1080p. 4K represents the horizontal resolution because there are numerous aspect ratios used in film — so while the horizontal resolution stays constant, the vertical resolution depends on the video source.

4K = Ultra Definition Television

There are several different resolutions that qualify as 4K.

QFHD (3840×2160): Quad Full High Definition (QFHD), at 3840 x 2160 pixels, doubles the 1080p high-definition television standard in both the vertical and horizontal dimensions. So it is like having 4 Tvs with 1080p.

8K Resolution: UHDTV, SHV

Ultra High Definition Television (or UHDTV, 4320p, and 8K) is a digital video format currently proposed by NHK Science & Technology Research Laboratories. It has roughly the same resolution as IMAX, which is about 16 times the number of pixels of existing HDTV (high-definition video). NHK advocates this video format as Super Hi-Vision (SHV).

SHARP demonstrated a direct-view 85″ LCD display capable of 7680×4320 pixels at 10 bpp.
