Hi.
I am very interesting in someone explanation and help regarding the issue I have in my system
In briefly, I am connecting my TV (dvi output->dvi to hdmi->hdmi input )to my philips TV. First, I am using the VGA output to a screen to configure the TV and its working. I switched the TV to be my primary display and disconnecting the VGA connector. until now, everything is OK. I get no signal from the computer when I switched the TV to another source (satellite etc...) and returns back to the computer.

The issue can be solved when I configured again using the VGA screen but the signal cannot stay through the DVI/HDMI.

Any suggestions ?
Thanks
