The First 4K channel in farsi is about to launch

4K is an up-and-coming video technology that promises a better quality picture when you’re watching movies or TV shows. But how does 4K work, and what does it mean for you? Hit play on the video above to find out.

The term “4K” refers to the resolution of an electronic display. A “display” could be the screen on your TV, your iPad or your laptop, and “resolution” means how many pixels there are in that display.

Pixels are the dots that make up on-screen images, and the more pixels there are, the sharper and more realistic images look. When we can see individual pixels, images look blocky and less lifelike, so we usually prefer displays with a higher resolution, and 4K is a very high resolution indeed. That’s why it’s sometimes known as “Ultra High Definition”.

In terms of tech products you can buy like TVs, 4K normally refers to a resolution that has 3,840 pixels along the horizontal line of the display, and 2,160 pixels vertically.
