I've always loved Matrox products and died a little when I had to give up my old Matrox Millennium card for an NVidia-based chipset. All my friends in print media tell me that they still love the Matrox 2D cards for their sharpness.

Well it looks like Matrox is going to release a new toy pretty soon:

<i>Matrox Graphics Inc., the leading manufacturer of graphics solutions for professionals, announces Extio™ F1400, the world's first remote graphics unit. With this solution, the user interface of the computer – the keyboard, mouse, monitors, audio peripherals, and graphics hardware – are separated from the rest of the computer by up to 250 meters (820 feet) of fiber-optic cable. Designed for professional applications, this product supports up to 4 digital or analog monitors at a time, and has passive (fanless) cooling.
...
The versatile Matrox Extio F1400 remote graphics unit (RGU) has a Matrox-designed graphics chip, 128 MB of graphics memory, dual-LC connector for fiber-optic cable, 4 DVI-I monitor connectors, 6 USB 2.0 ports (4 in front, 2 in back), integrated audio hardware, an optical connector for digital audio output, and analog audio connectors for a microphone input, line input, and line output. To meet different slot requirements, Matrox separately offers PCI or PCI Express (PCIe) fiber-optic interface cards for Extio products.</i>

I have no idea what this puppy will cost, but I can't believe that it would be cheap. Granted, I have no use for something like this right now... but in the future it might be nice to shove the desktops into the closet so I don't have all those CPU fans going in my bedroom...

Wow! That would be incredibly awesome!

It will probably cost more than four separate computers. <img src=http://lag9.com/biggrin.gif> The only thing Matrox cards had going for them back then was a good quality DAC at the output stage. Today, DVI is the standard, so DACs are irrelevant, and the legacy analog connectors all use good DACs.

If you just want remote control of your PC, why not use something like a wireless air panel (http://www.viewsonic.com/support/mobilewireless/airpanelsmartdisplays/airpanelv150p/)?

802.11b versus fiber, I'd take fiber. Plus, that quad LCD display they had on the website is making me very happy... :D

If you want four displays, just use two video cards!

Yes, and now put those four monitors 820ft away, and you get the Extio!

Considering fiber optic DVI cables cost around $20/meter for long runs, I wouldn't want to see the bill.

You can get DVI for around $0.75/ft and Fiber for about $2/meter from <a href="http://www.monoprice.com">Monoprice</a>. But then again, if you have a quad monitor set up and bought this device, you're probably not worrying about the cost of cables :)

I see fiber optic cable, but not DVI fiber cable. DVI-D has 18 signal wires.

I need to start looking into stuff like this...I need to find some way to combine my HEC and my computer system which are currently like 15 feet apart and very sepereate.

Fifteen feet (~3m) is no problem for a regular copper DVI cable; you could even go much longer, at least 5m and sometimes up to 10m depending on cable quality and total bandwidth. You can use a wireless keyboard/mouse with it.
