What is Display Resolution?

Display resolution is the number of pixels active on the screen. A pixel is a small dot on a screen. More pixels the better the resolution of the screen. Display resolution does not depend upon the size of your display but rather it depends upon the number of pixels active on the screen. For example, A small 5-inch display with 720p would have better display resolution than the old 24-inch display TV with 240p.

The 5-inch 720p display has more than 2 Million pixels active. This is why size can not be the only factor when buying a screen. Display Resolution is a very important factor to consider when buying a  screen.

Why is Display Resolution important?

Display Resolution is an important factor to consider when buying a screen because it affects the quality of the picture. You might probably be wondering what the quality of a picture or a screen is. Quality while discussing a screen refers to the amount of information shown on the screen at once. The higher the number of active pixels, the higher will be the picture quality. 

Low display resolution means a blurry picture/video. Vital information and detail in a picture might appear like an annoying big box. These details play a vital role in users’ experience. That is why display resolution is important to consider while buying a device with a screen.

What is FHD?
