dual-monitor

The system of pc is win7 32bit, the video card is ATI 4670.

The tv is philips 74xx series. And the monitor is Dell 19' that connect with pc via VGA.

The tv can receive the singal and show the pictures when booting the pc(bios self checking, the logo of windows 7), however the tv says there is no signal after the win7 login window shows.

I have installed the latest CCC and driver of ATI video card. Does anyone have idea for it?
