    duplicate screen bug, screen duplicates for 1 second then reverts to extend


    my hdmi cord running from my laptop to tv was working fine but one day it simply stopped. I updated my drivers, used win-key+P and forced changed the screens to duplicate, and uninstalled recent windows update and restarted my pc and nothing. The tv will show the duplicated screen for 1 second then swap back on its own. If anything, windows should simply let the screens stay duplicated until the 13 seconds are up for you to confirm settings instead of giving up instantly and not letting me do anything about it. Everything I see on this issue is like 3 years ago and nothing seems to work.

    :)
