Future Armadas in the E and M families, with improved graphics capabilities and dual display

.

 

.

 

 

 

 

.

 

support will be available in the second half of 2000, further enhancing its use with the

.

 

.

 

 

 

 

.

 

Microportable Projectors.

.

 

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

. Although the Armada product line currently does not offer any digital video ports (such as DVI or

.

 

 

 

 

.

 

 

 

 

. DFP), the Microportable projectors are capable of receiving digital video data thru a secondary

.

 

 

 

 

.

 

 

 

 

. connector. Plug-in graphics cards with such a capability can be installed on Armada’s docking

.

 

 

 

 

.

 

 

 

 

. stations (ArmadaStation), or any other Compaq desktop computer.

.

 

 

 

 

.

 

 

rd

 

.

There are 3

party PCMCIA graphics adapters that provide a digital DVI interface if needed; these

.

 

.

 

 

 

 

.

adapters either disable the internal Armada graphics controller, or configures the device as a multi-

.

.

 

 

 

 

.

monitor system.

.

.

EXT E R N A L MONI T OR RESOLUTION AND RE FR E S H RA T E S

.

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

. When it comes to resolution, the Microportable projectors will work best at its native resolutions of

.

 

 

 

 

.

 

 

 

 

. 800 by 600 (SVGA) or 1024 by 768 (XGA) pixels. They will accept anything between 640 by 480

.

 

 

 

 

.

 

 

 

 

. (VGA) and 1280 by 1024 (SXGA), based on model. SVGA projectors will not downscale from

.

 

 

 

 

.

 

 

 

 

. SXGA as the resulting image quality is not good.

.

 

 

 

 

.

 

 

 

 

.

Likewise, our Armada portables are all capable of displaying at the optimal 1024 by 768 while in

..

.

external-display mode, and many other combinations while in simultaneous display.

..

.

 

 

 

 

.

 

 

 

 

.

 

 

 

 

. A 60Hz refresh rate is the most common, especially if driving the internal LCD simultaneously; as

.

 

 

 

 

.

 

 

 

 

. refresh rate is increased, possible visual artifacts are eliminated. We do not recommend (though

.

 

 

 

 

.

 

 

 

 

. some projectors support it) the use of any interlaced mode.

.

 

 

 

 

.

 

 

 

 

.

The ability to display larger number of colors is dependent on the Armada model being used.

..

.

Higher amounts of frame buffer memory will allow for higher color depth. The high-end Armada

..

.

E700, M700, 7400 and 7800 series all have 4MB and 8MB of graphics frame buffer (based on

..

.

model), which easily allows for the display of 1024 by 768 pixels of resolution at true color (24

..

.

bits, or 16 million colors). Many users of portables with less graphics memory will find that

..

.

lowering the resolution will increase the color depth. This is a trade-off that can be evaluated prior

..

.

to the presentation. Presentations with motion-video will likely benefit from the higher color
