ASK Proxima C410 and C420 (DP8200x) Projectors

Frequently Asked Questions: Computer

What resolutions is the projector capable of displaying?

VGA, SVGA, XGA, SXGA, SXGA+. This projector has a native resolution of XGA. For best results, adjust your computer

resolution to XGA (1024 x 768).

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

goes out after a period of time.

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.

If you have disabled the computer power savers and screen savers, and the issue persists, it may be due to a setting in the

projector. The projector automatically displays a black screen after no active source is detected for 30 minutes. This black

screen helps preserve the life of the projector. The image returns when an active source is detected or a remote or keypad

button is pressed.

Screen Save

You can make the black screen appear after five minutes by turning on Screen Save in the Settings > System menu.

There are six time options for the Screen Save feature. They range from five minutes to 30 minutes in five-minute

intervals.

Power Save

The projector also has a Power Save feature that automatically turns the lamp off after no signal is detected for 20

minutes. After 10 additional minutes with no signal, the projector powers down. If an active signal is received before

the projector powers down, the image is displayed. You must press the Power button to display an image after 30

minutes have passed. When Power Save is enabled, Screen Save is disabled.

The image appears to be stretched vertically or horizontally.

The Aspect Ratio is set to 16:9 instead of Native or 4:3, which is required for computer images. To change the aspect ratio,

press the Menu button on the keypad, then go to Main > Picture > Aspect Ratio. Select Native or 4:3.

The default setting is Native, which allows the projector to adjust to incoming signals automatically. Setting the aspect ratio

at 4:3 or 16:9 forces all incoming images to that ratio.

I am playing a DVD on my laptop, but the projector displays a blank screen.

If the DVD plays satisfactorily on your laptop, you should be able watch it with the projector. However, some laptops do not

have the resources to play the movie on both its own screen and through the projector. When this happens, you will probably

just see a blank screen. To solve this issue, press and hold the FN key on the laptop, then press the appropriate function key

(F1, F2, F3, etc.). The function key should be labeled "LCD/CRT" or will have a monitor icon on it. You may need to press the

function key a couple times. When you do this, you cycle through three settings: the image only on the laptop, the image on

both the laptop and projector, and the image only on the projector. You want to set it so the movie appears only on the

screen.

The LED on the projector keypad has changed. No image is projected. What is wrong?

The projector has an LED next to the Power button. It shines green or red, depending on the state of the projector. The LED

can help you troubleshoot projector problems. The LED Error Code Guide is available for download from the ASK Proxima

website.
