This is your monitor's native resolution-usually the highest resolution your monitor can support. Tap or click the resolution slider and drag it until you find the resolution marked ( Recommended). Tap or click PC and devices, then tap or click Display. (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.) Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
To see your monitor's native resolution, check the display settings in PC settings. It's a good idea to set your monitor to the resolution it was designed to display (called the native resolution).
