ASK C20 and C60 Projectors

Frequently Asked Questions: Computer

The computer image is not displayed on the projector.

Connect all cables tightly.

Turn on the projector first, then the computer.

If you're using a laptop and the computer image still does not display on the projector, you may need to activate the

computer's external video port with special keystrokes. Press and hold the FN key on the laptop and then press the

appropriate function key (F1, F2, F3, etc.) that's marked LCD/CRT or marked with a picture of a monitor. (Refer to

the laptop activation chart or your laptop documentation for further video port activation instructions.) You may

need to press the function key more than once. Many laptops cycle through a series of configurations at each key

press, including image on the screen, but not on the laptop, image on both the screen and laptop, image on laptop

only. Be sure to wait five seconds or so after pressing the function key. Sometimes it takes the projector a few

seconds to communicate with the laptop.

If you are using the optional Enhanced Connectivity Module, try removing it, and connect your cable directly to the

projector. If the computer image displays, the Module may need to be replaced.

The projected image reverts to the ASK Proxima logo or to a blank screen during periods of computer inactivity.

This may be caused by a power saving utility on the computer that disables the video output signal after a specified period of

inactivity. Disable all power saving programs and screen savers on the computer to prevent signal interruption. Refer to the

computer documentation to disable power saving utilities.

The top or the bottom of the image is wider than the other ("Keystoning" problem).

You can correct for keystoning by making sure the projector is placed perpendicular to the viewing screen. Raise or

lower the elevator foot on the front of the projector to obtain a rectangular shaped image. It may be necessary to

place the unit on a higher surface to correct the image.

Press the Keystone + or Keystone – button on the remote control or on the projector keypad to digitally adjust the

image. Use this method when you cannot solve the keystoning issue by changing the projector placement.

You can also adjust keystone in the Basic menu. Press the Menu button. Go to Basic>Keystone.

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 Adaptor Default. If you are using a

laptop, always use AC power, not the battery.

The computer image does not appear, only the message, "Signal out of range". Or the images on the screen are

torn and the message, "Perfecting the image" periodically appears.

The computer refresh rate may be too high or too low for the projector to synchronize with. On the computer, 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).

Set the refresh rate to 60Hz, 75 Hz or Adaptor Default. In Windows 2000 and XP, the Refresh Frequency setting is on the

Monitor tab.

The image is tinted or the color is distorted, or the image is 'ghosted'.

Reset the projector to factory defaults. To do this, press the Menu button, then navigate to the Advanced menu.

Select the Reset option.

Change sources. Try plugging the projector into another computer.

If the color problem persists, 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.

Upgrade the system software.

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.
