The clarity of text and images on your screen can depend largely on how you set your monitor’s screen resolution. At high resolutions, such as 1280 by 1024 pixels, you can display more on the screenâ€”but text and images will look smaller.
At lower resolutions, such as 800 by 600 pixels, objects will appear larger but may look jagged and less sharp. The optimal setting to choose really depends on your monitor and the larger the monitor the higher resolution it supports. Most newer computers have already been pre-configured for you, but you can try various options to see what works best for you. You can quickly change this setting by right-clicking any empty space on your desktop, then choosing “screen resolution” in the menu.
