.
.
.
.
.
.
.
.
. The following Armada Products have a dual graphics controller architecture:
.
.
.	• Armada 7300 and 7400 series
.
.
.
.	•
.		Armada 7700 and 7800 series
.
.
.
.	• Armada E700 / M700 / E500 / M300 series
.
.
.
.	•
.		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.

.
.	E XT 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
..
