What is resolution? Resolution is slightly
ambiguous term.
Context for this project is Digital Resolution.
Digital Image resolution is usually defined as the pixel count. (Width x Height)
TV: Standard Definition: 486X440 – 640x480 to 852x480
TV: Hi Definition: 1366x768 – 1920x1200

WHAT IS HD Resolution The high definition comes in two flavors which are 720p (HD
ready) and 1080p (Full HD).
Both standards offer more picture information than the standard definition formats.
The more pixels that make up an image, the more detail you see - and the smoother the appearance of curved and diagonal lines.
A high pixel count also enables images to go larger before they break up, which suits the trend to bigger TVs. The real difference between 720p and 1080p is the minimum viewing distance from TV about two meters.
Increasing pixel density leads to closer viewing distance without the pixel grid becoming obvious to viewer.

WHAT IS Ultra HD Resolution
Ultra HD takes that on to the next level.
A 4K image - or Ultra HD - enables user to sit 1.6m from the screen.
The Pixel Resolution we get ends up being 3840 x 2160.
In 8K – or Ultra HD, its 7680 X 4320.

4K Resolution
Defined as Ultra High Definition Television (Ultra HD, UHD, UHDTV)
Standard Has been approved for 4K (3840x2160) & 8K (7680x4320) resolutions
4 and 8 times as many pixels as standard HD.
Better color representation & higher frame rate support (120fps)
Upscaling from lower sources is easier.

4K Resolution Specifications "Ultra High-Definition", or "Ultra HD",
Have an aspect ratio of at least 16:9
Can present native video at a minimum resolution of 3,840 x 2,160 pixels.
4K UHDTV (2160p) is 3840 pixels wide by 2160 pixels tall (8.3 megapixels), which is four times more pixels than 1920 x 1080 (2.1 megapixels).
8.3 MegaPixels

8K Resolution Specifications
8K UHDTV (4320p) is 7680 pixels wide by 4320 pixels tall (33.2
megapixels), which is sixteen times more pixels than current
1080p HDTV, which brings it closer to the detail level of 15/70
mm IMAX. The p in 2160p and 4320p stands for progressive scan or non-interlaced.

Offered extra resolution so image quality better We are eager to see the bandwidth that will be needed
as well as the possible new media formats that will accompany.
Ultra High Defination Movies should look Awesome !
