Windows 7: Problems connecting an external screen

Problems connecting an external screen

Hello,

I have a ATI 4670 graphic card 1GB. Until recently everything worked fine. I'm using one of the DVI ports to connect to my main screen. DVI Port is the second, connecting LCD TV via HDMI Adpter, that I received from the manufacturer. Like I said earlier everything worked properly until about two weeks - three.

LCD TV has two primary devices are connected. One of them is a computer via HDMI. Cable Box II is a scart connection.

Until recently I could switch easily between sources for LCD TV. Between HDMI and scart. Now the situation is different. LCD TV at the moment and PC can not produce a connection between them.

LCD TV displays a message that there is no signal reception. Computer does not recognize a connection.

This problem resolved itself, after several hours of rest. Suddenly I turn on the TV and I see he can take an image from PC. After watching the content from the PC through the TV. I'm going through scart source for Cable Box, watching a few hours, and when I return to the source of the HDMI No picture again. Once again a few hours of work and then returns the image. Meanwhile I tried everything, restart the computer, reset the TV. Cut off the driver and restore it. No matter what I'm doing nothing does not solve the problem. And after a few hours it comes back as if nothing happened. And when I pass a second source of Cable Box it's gone.

I would love if you can help me a problem.

Have you tried a new cable?

Unfortunately not. I have no other cable.

What I tried to connect the LCD TV via VGA cable (through the same port) using Adpter (DVI TO VGA) which came from the manufacturer.
Everything worked fine.

Sounds like it might be a bad connector on the one end or something.
