ASK Proxima C300 and C300HB (DP8000 and DP8000HB) Projectors Frequently Asked Questions: Video

The colors on the video image are incorrect.

Do the following after attempting to adjust the color in the Picture menu. You can access the picture menu by pressing the Menu button and navigating to Basic > Setup > Picture.

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

3. Try different cables. It could be a faulty cable. Check the cables for bent or broken pins. If any pins are damaged, the cable will need to be replaced with an ASK Proxima-approved cable. Please contact ASK Proxima Technical Support for part information.

4. Upgrade the projector system software. More information about software upgrades is available on the C300 Software webpage.

5. If the projector still will not display the image, it is possible that there is an internal problem that requires repair. Take the projector to your dealer or contact ASK Proxima Technical Support.

The image is not perfectly rectangular. ("Keystoning")

When a projected image is wider at the top or the bottom, or taller on the right or left side, we say that the image is 'keystoned'. Keystoning happens when your projector is not perpendicular to the screen, either in the vertical plane or the horizontal plane.

Correcting vertical keystoning

If you use the elevator to tilt the front of the projector up so you can get the image higher on the wall, the image will suffer from vertical keystoning. Likewise, if you mount the projector on the ceiling and need to tilt it to get the image on the screen, you'll also get a keystoned image.

1. Try raising or lowering the projector. You can correct for keystoning by making sure the projector is placed perpendicular to the viewing screen. For example, it may be necessary to place the unit on a higher surface to correct the image. Or you can add an extension to a ceiling mount that allows you to mount the projector lower.

2. Finally, change the Keystone setting. You can use the Keystone function on the projector keypad or in the menu of the projector to adjust the keystone digitally. You can adjust keystone between -15 to +40 degrees.

Keypad

Press the Keystone Up arrow to reduce the upper part of the image, and press the Keystone Down arrow to reduce the lower part. You can adjust keystone between -15 to +40 degrees.

Press the Menu button. Navigate to Basic > Keystone and press Select (keypad) or L button (remote). Use the Left and Right Arrow buttons or trackball to adjust the value. Press the Select or L button to confirm your change.Finally, change the Keystone setting. For most models, you can use the Keystone function on the projector keypad or in the menu of the projector to adjust the keystone digitally.

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.

Please note that it is always better to achieve a rectangular image by moving the projector. Some images look much better when there is no digital keystone correction.

The image appears to be stretched vertically or horizontally.

This may be the result of the Aspect Ratio being set to 16:9. In the menu of the projector, navigate to Basic > Setup > Picture > Aspect Ratio and make sure 16:9 is not selected.
