Indeed, rather than requiring manufacturers of televisions or video projectors to be compatible with a technology like MHL, some have developed this small equipment that already works with the existing fleet.

HDTV (high-definition television) derives from computer technologies. LCD screens or LED computer monitors are produced with 1080p, 4K or even 8K resolutions.

These high-resolution or very high-resolution screens were designed for computers, and then an interface was added to make them living room televisions.

- 1080p or 720p refer to the resolution of the screen. This number refers to the number of vertical pixels.
- 4K refers to a resolution 4096×2160 pixels i.e. 2160 vertical pixels.

Today's TVs use the following formats :

- 720p 1280 pixels wide by 720 pixels high.
- 1080p 1920 pixels wide by 1080 pixels high.
- 4K 4096 pixels wide by 2160 pixels high.
- 4K Ultra wide TV 5120 pixels wide by 2160 pixels high.
- 8K 7680 pixels wide by 4320 pixels high.

Before HDTV, TV broadcasting had only 480 vertical lines. What is called today 480p. In addition, we have gone from a 4 : 3 image format to a 16 : 9 format. This was done because of the film industry, which has long used a format Widescreen 16:9 for his creations.

Computer screens have grown and have smaller pixels. An original VGA

This cable is used to connect a graphics card to an analog computer screen. The VGA connector consists of 15 pins arranged in three rows. This port is available in two generations : the original version and the DDC2 version, which allows automatic~type monitors.

monitor had only 640 x 480 pixels.
Today the video is watched on computer as well as on living room television.
These screens are compatible, only formats and resolution differentiate them.
