    Open Device Manager. Do you see any red or yellow warnings? Jack E/NJ

     there is a warning type sign on the display driver and you can also see the error.

    Simply right click on the driver and uninstall it. Exit Device Manager without re-installing anything. Then reboot the system and let Windows auto re-detect the display driver and auto re-install it. Jack E/NJ
