Hi all, I'm having an issue and nowhere on the internet I can find people exclaiming the same problem, so here I go: My primary gaming monitor is connected through DVI (144hz). My secondary monitor is connected through HDMI (TV). The gaming monitor is great for gaming, of course, and the second one is great for watching movies. Everything works flawlessly except for one thing: When my girlfriend turns on the TV while I'm playing a game, Windows automatically detects the TV and starts duplicating my screen (even if my previous setup was "Only use primary monitor" or something), which results in my game going completely black. I have to ALT+TAB and select the game again to continue. It's not a big deal, because the game doesn't crash or anything, unless I'm playing a multiplayer game where this stuff could mean my death, which may even result in my team losing. How can I stop my Windows 10 from automatically detecting the TV? I want Windows 10 to do absolutely nothing unless I tell it to.
