Compaq Microportable Projectors & the

Armada Graphics/Video Capabilities

INTRODUCTION

This whitepaper explains how to optimize the customers’ experience with Compaq

Portable Computers when used in conjunction with a Compaq Microportable Projector.

The Compaq series of Microportable Projectors are a 3-4.5 lb. multi-sync projectors

capable of displaying images at resolutions of 640*480 to 1280*1024. The native display

mode is 1024*768 (XGA) for the high end model and 800*600 (SVGA) for the value line,

and it automatically scales up or down other resolutions using state-of-the-art algorithms

built into the hardware.

The graphics acceleration technology and architecture of the Armada Family of Portable

Computers delivers brilliant, professional quality, photo realistic images while

maintaining outstanding performance. Its strength in 2D image display, 3D rendering,

DVD playback and higher bus and memory speeds and bandwidth make this the best

overall solution for the graphics and video needs of Compaq’s customers.

By providing separate timings (on the high end Armada M700/E700/7400/7800 systems)

for an external (CRT or projector unit) and an internal (LCD) display device, the dual

display technology enables users to display the same image simultaneously on separate

displays with different refresh rates and /or resolutions. Additionally, with the support of

the Windows98 Operating System, the dual display technology also enables users to

display different images simultaneously on separate displays at different refresh rates, if

needed.

In conjunction, the Microportable Projectors & the Armada Portable Computers provide

the stunning graphics presentation solutions that todays’ professionals desire to make a

lasting impression on their clients.
