in the world of computer graphics, the resolution is king. Resolution of image or appearance is defined as how crystal clear picture or view it. For computer monitors, the resolution described as how many pixels that can be included in the display. so a monitor that has a resolution of 1280 x 768 1280 display 768 dots on each line. The basic rule, the higher the resolution will create the look sharper and cleaner, but also smaller.
If you use a computer to edit the graphics or games, with increasing resolution will display a sharper picture and details. Kulitas resolution depends on the monitor and graphics card. It is pointless if you have an expensive graphics card, but the monitor is outdated and only has a capacity of 640 x 480 resolution.
