    Windows Card?

    This appears to be a Windows card. The correct link for the announcement is here:
    "The Parhelia DL256 PCI is OpenGL® and Microsoft® DirectX® compliant and ships with display drivers for Microsoft Windows® XP and Windows® 2000."

    The product page is here:

    Oddly, though it shows several display combinations, it never shows two 30" displays. This suggests it is a single-DDL card, with a 2nd regular DVI port.

    No mention of Mac drivers anywhere, and I can't get into the private Apple store the AppleStore link seems to point to.

    Never Again Matrox

    I will NEVER buy another Matrox product. With the lousy support given to their now forgotten RTMac video board (the move to OS X was too much for them to spend a little money and come up with a stable driver) BUYER BEWARE with this company.

    Never Again Matrox-Me Too

    I also had a terrible experience with this company. The RTMac fiasco cost me, and apparently others, a great deal of money and frustration. What was worse, they continued to market the product to new customers, knowing that the card was useless on modern Macs. Anyway, this was such a bad experience, I actually registered to submit this post. (Although I do read MacNN every day :] )

    I'm not finding mention of a Mac version of this card anywhere, either, and it's not showing up on any of the US Apple Stores online--regular, Business, or Education.

    If this is true, though, it would be very big news--both the first true workstation graphics card available for the Mac in a long time, and a fairly high-powered card that can go in a PCI-X slot, giving people who need more than one beefy card an option.

    Not that I have much love for Matrox, but more choice = good for us.

    Some of us mac users also have to use a PC, It would be great to use the 30" with a KVM switch for both PC and MAC. This is just a card that will allow windows users to get their buggy hand on a premium display or people like me to have use of a great display all of the time.

    Only card?... NOT!

    Look around a bit, there are other cards that does what this one does AND you don't have to put up with Matrox arrogant support. Just like with the RT Mac card, as soon as they've gotten enough of your money they will stop supporting this product and bring out another. True thieves.

    PCI MatroxCard Apple30"

    I have a HP xw4200 workstation and bought the Matrox card to run the Apple 30” display. I was concerned when I heard of the many customer service problems Matrox has, but I went ahead and purchased their card when I could not find one from ATI or NVIDIA for less than $1000US; I paid $600 for the Matrox card, mail order. It should be noted that I do not play video games or run any CAD or 3D programs, just regular office applications. That the card came in an unmarked white box with no marketing whatsoever scared me a little bit. Instructions are minimal and not terribly helpful, but the card worked fine. I have the card installed in a regular PCI slot, as it did not fit in the PCI Express slot of my computer. While Matrox claims their card can run the Apple 30” plus a second monitor, performance for the Apple monitor suffers when a 2nd monitor is attached so I don’t recommend it. With two monitors hooked up, you’ll see “refresh lines” going down the screen of the Apple 30”, really annoying. However, the card is more than capable of driving just one big monitor
