My video card has a VGA and an ADc connector. Connected my 19" monitor using VGA connector.
Got a Belkin ADC to DVI adaptor for the ADC output.
Got a DVI to HDMI cable to connect to the TV.
Everything plugged together Ok.
On powering up the Mac, the Widescreen TV shows the grey screen with the apple symbol and the spinning wheel, this disappears and the 19" monitor comes on. This displays the desktop picture, but no icons appear and that's all that happens. Power off theMac, power off the Widescreen TV, power on the Mac and it comes up normally. The grey bootup screen appears on the 19".
So how do I get the system to recognise BOTH displays. I've played with the System Preferences, but because the system won't recognise both screens I can't switch on the mirror option.
Any thoughts on the problem welcome.
