I have an old XG-E650U projector and I am trying to get it to connect with my acer aspire 8930g laptop so I can watch a movie (yes, I know it is low res but its bigger). I have the vga cable securely in and have tried both analog and digital mode on the projector but I still can't get a connection. I have tried both hitting FN+F5 and windows key+p but neither worked. What is the problem? Thank you for your time.
