I have a radeon hd 6950 as my card, and I used to just run a dual monitor set up. I recently got a TV for my room and I wanted to connect it to watch movies or play single player games on controller. When I connect my PC to my TV via HDMI, I lose picture in my 2 monitors and my TV detects that there's something plugged in to it (and asks me to switch to the correct channel), but I get a black screen there too.
If I restart my computer, I'll get signal in the TV and one of my monitors, or in both monitors but not my TV. Then I can go to my display settings and get signal in whichever 2 screens I want, but only 2 screens.
I'm okay with 2 screens. 3 would be better but I'm not sure if there's anything I can do on that front. My main concern is I have to restart my pc every time I want to use my TV as a display. Is there anything I can do about that? My TV isn't in a great spot, so I can't keep the HDMI cable from tv to pc in all the time.
