Matrox G550 Dual-DVI 
    
One of the reviews that had the most postivie feedback and requests for more information 
was the Matrox G450 
review I did some time ago. To be quite honest we were surprised by the number 
of our readers who thought that a video card that suited their work needs was 
more important than a card that suited their gaming needs. 
Matrox recently contacted us again with the release of their Millennium G550 Dual-DVI. 
What is Dual-DVI and why should anyone consider it? The answers are quite illuminating.

First 
Impressions
The very 
first thing that struck me was just how small this video adapter is. I own network 
cards that are larger! Matrox has gone very far in making their products small 
while incorporating a very wide array of features. The next thing that struck 
me as odd was that the core of the video card is cooled only with a heatsink that 
is very reminiscent of the ones that came on Intel's 486 processors. One 
feature that contributes to the G550's diminutive size is that it only uses two 
memory chips which on the review board were made by Samsung. We are accustomed 
to seeing four or more memory chips on video cards and obviously going with this 
more expensive memory solution has allowed Matrox to have a more clean PCB.
Consipicuously 
missing from the card are a TV out connector (you can order a special cable for 
that connector) - or a normal 15 DSUB video connector! While the regular G550 
easily accomodates dual analog monitors the G550 Dual DVI is specifically engineered 
for the higher end market that requires output for dual digital display. What 
is particularly nice about this arrangement is that Matrox sent my evaluation 
unit with a cable that converted the single digital output to dual DSUB outputs 
for use with analog monitors or LCDs. Also included in the box was the Dual-DVI 
cable that splits the DVI output of the card for two displays. This gives the 
G550 Dual-DVI the ability to support upgrades in display devices later on. Previously 
you'd have to buy a card that was engineered for Dual-DVI output from the get 
go. Good work Matrox!
