• IRP 4500 only: Make sure that the cables between your

computer and the projector are all connected properly. Refer

to“Cable Connections” on page 15.

• Make sure you have selected computer on the projector control

panel (or remote controller).

• Change the video resolution setting of your computer display

controller to agree with your projector. Change the monitor

model setting so that the output video refresh rate is not more

than 75 Hz.

• Shut down your Windows or Macintosh operating system, cycle

computer power, and restart the computer while leaving the

projector on.

If you are getting video from the computer but the image is of poor

quality or unstable:

• Refer to “Auto Image” instructions in your projector’s manual. It

may help to disable your Windows screen saver while making

this adjustment.

• Adjust Brightness, Contrast, Tint, and Color (refer to the

projector’s manual).

• Change the video resolution setting of your computer display

controller to agree with your projector. Change the monitor

model setting so that the output video refresh rate is not more

computer power, and restart the computer while leaving the

projector on.

If you have a portable or laptop computer and when you are

connected to the projector you get a projected image but the image

on your computer display disappears:

• You will need to set up your computer to re-activate its built-in

display. Refer to your projector manual or your computer manual

or call PolyVision Technical Support at 1.800.620.POLY.
