So for some reason when I first plugged my PC into my TV via HDMI it worked fine i set the resolution ect ect and everytime i turned it on it was fine, then I downloaded SWOTOR and went to play it, it bugged out hard the screen flashed like crazy and basically I had to turn the PC off, since then I cant get the PC to display in computer only mode only duplicate or extended but I have to change it when I turn the pc on (using windows + P) as I get no signal whereas I ever had this issue before does anyone have any awwnsers or solutions as im stumped
