There are many types of computer monitor function and here we will spread the light on various monitor function in computer with uses one by one.

Pixel: Huge amount of pixels are existed in the screen of computer monitor which have small square form dots in nature. Some people are also called of picture elements, and when electron beams get more heat then those pixels can turn on the illuminate mode. They can be empty with decreasing the intensity of beams, displaying the pictures on screen while activating the pattern of pixel elements. Every picture elements are stored in the RAM as code form which is inserted input with keyboard. Best quality of computer screen totally depends upon the huge number of pixels on the monitor that means if more pixels are presented on the monitor screen then picture quality much better, and those pixels might be different colors with their intensities which help to display the picture.

Best Resolution: Better computer monitor resolution varies according the number of pixel which has to provide help for displaying the image on the computer screen. The total number of horizontal pixel is known as main resolution as well as total number of line which display on the computer monitor is known as vertical resolution.

Frame StructureFrame structure is computer screen which have to contain fully information on the computer screen is called the frame. Frame rate must be more high for continuing images on the monitor, but one problem can be created like as laser flickering while high frame rate.

Video Bandwidth: With help of video bandwidth, capacities of computer monitor can be found. Need better video bandwidth for getting best output frequency to monitor.

Signal Synchronizing: All pixels take the form of picture while putting the beam light entirely on the display. This process has been done with using the well combination of coils which using for providing good strength to electron beams.

Display Images ScreenComputer screen is totally covered to phosphors, and image displays on it. That scans over computer monitor from top to bottom with continuing without any hindrance until scan both pages. In this first pass, skip every line and in second pass scan all lines that are missed during first pass, and finally full image will be display.

Non Display ScreenIn this section, all lines are ready to scan in one pass on the display. For getting quality images need high quality display to interlaced display. In the interlaced display, all lines are scan one by one from top to bottom line in continue nature.
