How to Find Your Screen Resolution

Your current screen resolution tells the monitor how content is displayed. Screen resolution is determined by the monitor and video adapter. A higher screen resolution uses more pixels, which makes images appear sharper on your screen. It also displays more items on the screen and uses smaller icons. A lower screen resolution uses less pixels and displays less items on the monitor. Finding the screen resolution only takes a few minutes in Windows and Macintosh.
