Connect Sharp PG-A320X Notevision Projector to MacBook Pro computer

Check both input selections on your computer and your projector. They both need to be set on the same input to work. For example, if the computer is set at 1080 and the projector is set on 720, it wont work. They need to match. Good luck!

There are 3 different types of analog video signal ports on your projector; s-video, composite video, and RGB. Which one of the three are you using to connect your PC to?
The projector's resolution rate is XGA [1024 x 768]
If you are using a VGA cable designed and capable of handling 640 x 480 resolution; then it will not support XGAs 1024 x 768 signal. On the other hand, if the coaxial cable you are using is a multi band one that is capable of supporting VGA and XGA resolution signals, most likely the problem is not with the cable- although I have come across brand new cables that are defective.
Please let me know if this helps or else we'll try another approach :)

It is more likely to be a problem with the laptop. If the projector comes on fine then it isn't seeing the signal. Maybe check the cables and outputs. It may be a setting in the diplay properties. Or the video card has failed. Good luck

Make sure the connection from the pc to the projector is secure, also make sure the display settings on the computer are set to extend the desktop onto the projector, and that the projector is set to pc mode.

Keep pressing it...3x 1. you will see it at the projector 2. projector and laptop screen 3. just laptop screen.

Hold down ON button on the projector for about 3 seconds while the projector is being turned on.

video plug to yellow video in jack, audio to red and white.

You must make sure the Mac resolution is set to 1024 X 768, otherwise it won't be recognized by the PG M20X Sharp projector. This change in resolution will cause the screen size to get smaller on the mac but, it will allow the projector to recognize the computer.

if it is only when the computer is connected, replace the cable.

i suggest you do not have the projector too far away... 7ft away distance would be a Good resolution will also dimm don the square's image in the picture
