I have a gtx 750 ti and I'm trying to get my pc to detect my insignia tv. I've tried doing it through the gforce menu and checking to see if my drivers are up to date and they are. I even used the hdmi cord on my laptop and tv and it works fine but i can't get ti to work on my pc. Only thing i can think of is there is something wrong with the hdmi port. Anyone have any suggestions?
