I have connected a TV to the video output on my Dell Latitude laptop for the purpose of watching DVD's on a reasonable sized screen. I have installed it as a second monitor and it mirrors the laptop screen quite well until I try to play a DVD. I have no problems on the computer but the video screen on the TV is completely blank. I am using WinDVD and CSS Region Free software but I can't see where that would have any effect. I have tried altering the resolution and making the TV the default monitor but it has made no difference. Any pointers would be appreciated.
Many Thanks
