4. Apply the new resolution by clicking on the "Apply" or "OK" button.
5. The screen might flicker or go blank for a moment as it adjusts to the new resolution. If the new resolution is suitable and visible, keep the settings; otherwise, revert them back to the previous resolution or try a different one until you find a size that suits your preferences.
