Some machines use a control panel for the graphics make in question. Some use the Windows Control Panel.
-> But given it's so recent, why not use system restore and go back to what worked?
Windows 10 has been working excellent for the past few months. Yesterday I think I may have swiped my touchpad while typing and did something strange because all of a sudden the screen went BLUE then came up stretched wide. Then it went black and came back with 3" of black space around the tiny screen. After rebooting it came back with a stretched screen. I have not been able to resent the display. Now everything is fuzzy and stretched wide. I tried to find a solution. I saw that I needed to select "advanced" in control panel under display. That did not work. I have only 2 settings to choose from. Neither are of any help. Does anyone know how I can fix this or reset the display? Please and thank you.
