- Ultra HD: Resolution of 4K picture (3,840x2,160 pixels)
What is 4K(4K Resolution - 4,000 pixels):
4K Resolution relates to roughly 4,000 pixel Horizontal Display Resolution. Many distinct 4K resolutions are frequently used by digital television and digital cinematography.3840 x 2160 (4 K UHD) is the dominant 4K standard in television and consumer media, while 4096 x 2160 (DCI 4 K) is used by the film projection sector.
4K Resolutions:
- 4096 × 2560(16∶10)
- 4096 × 2304(16∶9)
- 3840 × 2400(16∶10)
- 3840 × 1600(12∶5)

Pixel Aspect Ratio(PAR) is a mathematical ratio that defines how a pixel's width compared to that pixel's height in a Digital Image.What is the difference between SD and HD:
