What is Display Resolution?
The number of Pixels displayed in your Monitor is called Screen Resolution.
It is represented as how many Pixels displayed in Screen height x Screen width. To get the screen height and width use these codes as per your programming language. The computer or mobile devices do not have standard screen resolutions.
It varies with every manufacturer and every computer model. So, the developers have to design their application to be compatible with the user’s device resolution limits.
Be it an application developer or a Web developer, everyone have to use any of these codes at some point of time.
