If you have more than one monitor, you will see both listed at the top of the right panel. Select the monitor you want to check. The options you see are those supported by both your monitor and video card. For example, if you have a 4K monitor but don’t see the option to change your resolution to 4K (3840 x 2160), it’s usually because it’s not supported by your video card (or vice-versa).
After selecting a new resolution, it will change immediately. You’ll also see a pop-up message asking if you want to Keep changes or Revert to the previous setting. If the new resolution doesn’t look right, click Revert. If the screen goes dark after changing your settings, that resolution won’t work with your display—after a few moments, Windows will revert to the previous resolution to correct the problem.
