Kilo is a 1,000-unit measuring unit represented by the letter “K.”

The tiniest controllable component of an image shown on a screen is a pixel. Image quality is usually better when there is a higher pixel density.


This is the pixel size of the screen. Assume your computer monitor’s resolution is 1920 x 1080. This indicates that the display is 1920 pixels horizontally & 1080 pixels vertically.

Resolution in Native Language:

The native resolution is the physical amount of pixels on your display, and it is often the highest. If you know your monitor’s original resolution, you can rapidly get a high-definition image.

So, a 4k display, Ultra HD and UHD TV are all referring to the same resolution, which is 3840 x 2160. You may also say 2160p. 

Your HD TV’s full HD 1080p picture is just 1920 x 1080. As a result, your 4k televisions can display 4 times the amount of information as a 1080p screen. A DCI 4k version is also available.

best 4k monitor has a pixel density of roughly 140 PPI and a pixel pitch of 0.18 mm. For 4k, you’ll need high-speed wires. 

Because conventional HD signals cannot be carried by RCA cables, the improved HDMI 1.4 connections offer 4K resolutions at 30 frames per second.
