What Are the Differences Between HD and SD Screens?

Image quality will vary depending on what type of screen you have. This is due, in part, to the screen definition. This means an HD (high definition) monitor will not produce the same image as an SD (standard definition) monitor. Check out our guide to better understand how these standards work.

I – Pixels

Nowadays, screens are made up of pixels. These are small squares that make it possible to show one colour at a time via additive colour mixing of the three primary colours: red, green and blue. The more pixels, the sharper the image, because of the higher detail offered.

II – Video definitions

These pixels lead us straight into definitions. In fact, video definitions are based on the number of pixels in width and height:

An HD screen is 1920 pixels wide and 1080 pixels high. This definition is ideal for 16/9 screens because they share the same ratio: 1920/1080 = 16/9 = 1.77. This type of image is also known as 1080p HD.

As for 720p HD, this video format is great for online use and is 1280 pixels wide and 720 pixels high.

Smaller standard definition formats also exist, which are adapted to 16/9 or 4/3 screens. This is the case for 640×480 (or 480p) format, which is ideally suited to 4/3 screens, since they share the same ratio.

III – How this applies to our screens

Our M7 TOUCH HD screen comes in high definition, which means it is 1920 pixels wide and 1080 pixels high.

As for our MS7, MS7 WL, MS9, M7 MULTI and M7WP screens, these are built with 800×480-pixel definition.

Last but not least, the screen on our M7 Initial monitor is 756 pixels wide and 504 pixels high.
