One of our customers has a Dell 4210X projector. They have trouble using it with a Vostro 1710 with integrated graphics (Intel GM965) running Windows XP. They want to use it in mirrored mode, but the projector usually does not recognise that it is receiving a signal. After some trouble shooting, I have deterimed that we can get it to work by going through the Fn + F8 cycle several times, waiting a few seconds each time to see if it works. This can take about 90 seconds, which is a long time in the middle of a presentation. Is there a more elegant way to do this?
