  • PC-->HDTV 48inch problem

    Ok I have my PC (GTX 275) Hooked up to my HDTV through HDMI. I also have a second monitor running via regular VGA cord. Randomly my TV will just go black for like 4-8 seconds and then go normal. Its like when you change resolution it goes black to apply it, about the same time frame. I don't know if its a refresh thing or what. TV is a insignia 48". Any help would be greatly appreciated.

    How long has this done this for (always or has it just started happening?) and also have you tried using a VGA to VGA connection from your PC to your TV? (your TV might have a VGA port).

    Have you noticed if anything sets it off or is it completly random?

      It is completely random,AFAIK it has happened since I hooked it up, also I read that HDMI was the best to use, but I will try the VGA wire

          This sounds like a weak digital signal... too far or it's picking up noise somewhere. Questions to think through: How long is your HDMI cable? Is it a cheap one? Are you running the cable close & parallel to any mains power cords? Are the connections solid?

          Also could just be a sync issue between your video card and TV. Check that the native resolution and refresh rate on the TV match your settings.
