Correcting horizontal keystoning

If you place the projector so that the lens is not perpendicular to the screen in the horizontal plane, the image can suffer

from horizontal keystoning.

If your image looks like the one above, slowly rotate the projector until the image is rectangular.

The image on the computer monitor and/or projection screen flickers.

Make sure that the refresh rate on your computer is set between 60 Hz and 75 Hz, or Adapter Default. If you are using a

laptop, always use AC power, not the battery.

"Signal out of range" or "Setting up image" message periodically appears.

The computer refresh rate is either too high or too low for the projector to synchronize with. For PC’s, go to Start > Control

Panel > Display > Settings > Advanced > Adapter (This varies by operating system and by video card. See your
computer/video card documentation for more information). If the adapter allows you to select a profile, choose 1024x768,

High Color, 60Hz. You might also be able to change the refresh rate on the Monitor tab.

For Macintosh, go to Apple Menu > Control Panel > Display or Monitor and Sound to change your resolution and refresh rate.

The image is tinted or the color is distorted.

1. Reset the projector to the factory default settings. Press the Menu button. Then navigate to Basic > Advanced >

Service. Select Factory Reset. Note that if you have created special settings (for example, colors and sources), these
will be reset to the original defaults.

2. Change sources. Try connecting the projector to another computer.
