How to set different screen resolutions for each user account in Windows 10/8/7
Screen resolution is a setting that determines how much detail and information is displayed on your computer screen and is measured horizontally and vertically in pixels.
Windows selects the best display settings, including screen resolution, refresh rate and color, based on your screen. These settings differ depending on whether you have an LCD or CRT monitor.
Although it is generally a good idea to set your computer’s screen resolution to its native resolution – the resolution a monitor should display because of its size, there may be a reason you want to change it. You can choose one of the recommended resolutions or simply let your eyes decide what suits you best.
