My guess only:

When you switch channels, your PC will re-detect the resolution of your TV but it fails to identify it. So the screen becomes dark.

Can your ATI driver force setting to the resolution of your TV? Or you can try to use direct VGA connection. It may help.

Thank you first.
If I use the VGA cable - D-Sub, it is limited to 13xx x 7xx only. It is OK.

Any one can use VGA cable with 1920 x 1080?

But, if I use the DVI-HDMI converter, there is no signal after I switch to TV and back to the computer screen.

Finally, I get the other PC to test it.
The new card ATI 4870 without any problem.
