Screen Resolution can be adjusted from the Desktop.
Select Start > Settings > System > Display, and look at the section that shows your displays and select the display you want to change.
In the Display resolution row, select the list and choose an option. It is best to stick with the one that is marked (Recommended). Monitors can support resolutions that are lower than their native resolutions, but text will not look as sharp and the display might be small, centered on the screen, edged with black, or stretched.
Next to Choose a refresh rate, select the refresh rate that you want. The refresh rates that appear depend on your display and what is supports. Select laptops and external displays support higher refresh rates.
