Always make all connections first !! after that : switch on the laptop, or else no detection of an external monitor/projection device is possible. Please check also your bios settings, some can be set to force simultaneous display of external screen and lcd of the laptop. some laptops also require ddc communication between external connected devices. Try to use a full wired ( except pin 9) VGA cable.
