Hey Guys

I'm running Windows server 2008 and have a 19" tft connected to the graphics card (x1950pro) as my main screen and also have a projector connected also with a dvi-hdmi cable but not always turned on.

When the projector is turned off everything is fine but as soon as I turn my projector on, my main monitor usually starts to flicker black every few seconds.

I know what the problem is here....it's vista trying to auto enable mirroring on the second display. Sometimes it succeds but most of the time it doesnt.

Is there any way of stopping it from doing this because to be honest its annoying and I dont ever want my displays mirrored cos it interfiers with HDCP protection on HD-DVD's and BD's

Thanks in advance :)
