Publication Date: December 1997
INTRODUCTION
Compaq Computer Corporation is pleased to announce the new Compaq TFT450
Flat Panel Monitor. This state-of-the-art active matrix color monitor
features a 14.5-inch, thin film transistor (TFT) liquid crystal display
(LCD). The space-saving flat panel design occupies less desk space, and
the display is adjustable for clear horizontal viewing.
KEY FEATURES
The key features of the TFT450 Monitor are:
o A 14.5-inch active matrix display with a 14.5-inch viewable image area
o A flat panel design with a much smaller profile than a traditional CRT
monitor
o Support for VGA resolutions up to 1024 x 768 at 75 Hz
o Automatic scanning with support for 12 factory-preset modes including
one Macintosh mode
o User-friendly digital controls with on-screen display (OSD)
o On-screen controls for brightness, contrast, position, digital
conversion, language selection, power management (including Display
Mode, Power Saver, Full Screen, and Serial Number), and factory resets
o Field Replaceable Unit strategy to allow many parts to be exchanged in
the field and thus cut costs
o Plug and Play readiness saves time in setup and configuration with
Microsoft Windows 95
o Universal Serial Bus (USB) pass-through interface - Plug and Play ports
with one upstream to connect to a PC and one downstream for use with a
USB peripheral such as a mouse or keyboard
o EPA Energy Star compliant
o Timer Sleep function allowing user to set a time for the display to
enter suspend and sleep modes and to "wake up" to normal operations

WARRANTY
Monitor
Compaq offers its Three-Year Limited Warranty for the TFT450 Monitor,
which covers parts and labor and includes on-site repair for the first
year. For the second and third years, coverage is parts only (for all
parts excluding the backlight bulb). Warranty upgrades and extensions are
available.
Backlight
The backlight bulb is covered by a One-Year Limited Backlight Warranty. A
separate backlight replacement program is available to extend carry-in
backlight replacement coverage to three full years. Please note that this
extension is parts only, and is honored on a carry-in basis only.
NOTE: It is possible that a TFT panel will retain an image on the display
if the monitor is left on with the same image for a prolonged
period. Image retention ("burn in") is not a warranted failure.
Compaq recommends that customers use screen savers or turn their
monitors off when not in use.
WARRANTY UPGRADE INFORMATION
Compaq offers manufacturer Warranty Upgrades for purchase or resale as

TFT DISPLAY
The TFT panels used in the TFT450 Flat Panel Monitor have over 2 million
transistors (3 per pixel) making up the monitor. The product
specifications permit a limited number of pixels to be inoperative. These
inoperative pixels may be dark dots (pixels that are always off) or bright
dots (pixels that are always on). Replacement of monitors that have so
few inoperative transistors that they are still within the specified
limits is not recommended because the replacement monitor will also have
inoperative transistors. Indeed, the replacement may have more than the
original.
The TFT panel is not considered defective if it meets the following
criteria:
o The number of dark dots visible on a white screen does not exceed 8,
with no more than 2 dark dots within 0.60 inch (1.5cm) of each other.
o The number of bright dots visible on a dark or black screen does not
exceed 5 (no more than 2 may be green) High-level bright dots (red or
green) are not to be within 1 inch (2.54 cm) of each other, and
low-level bright dots (blue) are not to be within 0.60 inch.
SPARE PARTS
To hold down costs and facilitate customer service, Compaq has implemented
a Field Replaceable Unit strategy. This strategy allows monitor parts to
be replaced in the field rather than exchanging the whole unit as is the
process for CRT monitors.
NOTE: Backlight replacements are honored on an on-site basis during the
first year of ownership only. Second- and third-year backlight
coverage (purchased separately) is honored on a carry-in basis only.
The major spare parts for the new TFT450 are listed in Table 3 on the
following page. Detailed service and spare part information is available
in the COMPAQ TFT450 MAINTENANCE AND SERVICE GUIDE, which can be ordered
through normal service channels.
