HDTV Modes
The Compaq Microportable Projector is capable of displaying 
various High Definition TV (HDTV) display modes. A variety of 
sources can be used to provide HDTV data to the projector for 
display. Some of these sources are:
■Digital-VHS (D-VHS) player
■HDTV-DVD player
■Satellite Dish HDTV receiver
■A variety of DTV tuners (to receive programming over the 
airwaves)
■Game stations
Most of these sources will provide an analog component video 
output, a standard VGA output, or a standard digital DVI output. 
The color information can be either in YPrPb (default) format or 
RGB format. The user can switch between these using the 
on-screen display menu adjustments by selecting “A/V & HDTV 
Control.” Refer to “Introducing the On-Screen Display Menu” in 
Chapter 3 for more information.
The projector is capable of processing HDTV data provided 
either on the standard VGA connector or the DVI interface. Use 
the VGA-to-HDTV/Component video cable that comes with the 
optional Home Theater Kit to feed the component outputs to the 
VGA input connector.

The following modes are supported on the DVI interface:
■HD0
❏640 x 480p
❏1280 x 720p
■HD1—1920 x 1080i
When displaying HDTV content, it is recommended that you 
display it in its native 16:9 widescreen mode. For this, you may 
need to select the HDTV Fill to Aspect Ratio mode on the 
projector to preserve the height-to-width relationship of the 
material. Note that in this mode, you will have black stripes on 
top and bottom of the projected image, just as you see on a 
standard TV set when viewing widescreen content.
A desktop or notebook computer can also be used to generate a 
HDTV video stream. Capable computers should be able to 
read/acquire the HDTV data and blend it into the desktop 
graphics. The composite image is then sent to the projector for 
display. In this case, the projector displays the image at the 
standard 4:3 aspect ratio, just as it would any other computer 
graphics mode. The projector processes the data as it comes from 
the computer.
When displaying HDTV content in a window as part of your 
desktop environment, it is recommended to project it in the 
computer’s native 4:3 mode since the computer has already 
embedded the HDTV video stream in widescreen format within 
the window. To do so, you may need to select the Fill to Screen 
mode on your projector to preserve the height-to-width 
relationship of the material.
Regardless of the source, the HDTV formats are generally of 
higher resolution than that of the projector (XGA, or 1024 x 768). 
Therefore, the projector will normally downscale the HDTV data 
to fit the complete image within the displayable 1024 x 768 
resolution.

Care and Maintenance
This section explains how to care for and maintain your Compaq 
projector during normal everyday use.
Protecting the Projector
To protect your projector from overheating and other types of 
damage, follow these suggestions:
■Use only a power source and connection appropriate for this 
projector as indicated on the product label located on the 
bottom of the projector on the elevator foot.
■Do not overload an electrical outlet, power strip, or 
convenience receptacle. The overall system load must not 
exceed 80 percent of the branch circuit rating. If an extension 
cord or power strip is used, make sure that the cord or strip is 
rated for the product and that the total ampere ratings of all 
products plugged into the extension cord or power strip do 
not exceed 80 percent of the extension cord or strip ampere 
ratings limit. Refer to the product label located on the bottom 
of the projector on the elevator foot.
■Install the projector near an outlet that you can easily reach. 
Disconnect the power cord by grasping the plug firmly and 
pulling it from the electrical outlet.
■Unplug the projector from the wall outlet before cleaning. 
Do not use liquid cleaners or aerosol cleaners.
■Slots and openings in the cabinet are provided for ventilation. 
These openings must not be blocked or covered. Never push 
objects of any kind into cabinet slots or other openings.

Care and Maintenance
■Do not drop the projector or place it on an unstable surface.
■Do not expose the projector to rain or moisture.
■Do not allow anything to rest on the power cord. Do not walk 
on the cord.
■Do not allow the projector to be exposed to high 
temperatures.
■Do not open the projector or attempt to service this product 
for any reason other than to replace the lamp module. Adjust 
only those controls that are covered by the operating 
instructions. If the projector is not operating properly or has 
been dropped or damaged, contact your Compaq authorized 
dealer, reseller, or service provider.
Cleaning the Lens
To minimize the risk of damaging or scratching the lens surface, 
follow this cleaning procedure. First, remove any dust particles 
from the lens by blowing them off with clean, dry, deionized air. 
However, this may not be a convenient method, and an alternate 
method is described below.
To clean the lens, use only a clean cloth and follow these steps:
ÄCAUTION: Do not spray any type of fluid or cleaner directly on the lens 
surface. Do not use liquid cleaners.
1. Wipe the lens in a single direction with a clean, dry cloth. 
Do not wipe back and forth across the lens surface.

2. If the cloth is dirty or smears the lens, wash the cloth. If the 
cloth is still dirty after washing it or the fabric is damaged, 
replace it.
✎Do not use fabric softener when washing a cleaning cloth or 
softener sheets when drying the cloth.
ÄCAUTION: Do not store a cleaning cloth in contact with the lens for a 
long time as doing so may contaminate the lens with dye from the cloth. 
The cloth can be contaminated if left in the open air.
Replacing the Projector Lamp Module
ÅWARNING: When the lamp reaches its end of life, it may pop or 
rupture. To reduce the risk of personal injury, be careful when removing 
the lamp cover as broken glass may be present. Never open the lamp 
cover while the projector is operating or when the lamp is hot.
The projector will alert you when the lamp approaches its failure 
mode or end of life. When the message “Lamp May Fail Soon. 
Replacement Suggested” displays on the projection screen, you 
should change the lamp as soon as possible. Contact your local 
Compaq authorized dealer, seller, or reseller to purchase a spare 
lamp or have the lamp changed. To locate a reseller near you, 
refer to the Worldwide Telephone Numbers booklet that came 
with your projector. You can also purchase a lamp directly 
through 
http://www.compaq.com/products/projectors.
