I run three monitors in my home office. For awhile I used to do this via two video cards, but I had a lot of stability problems in Windows Vista and the release candidate for Windows 7. I disconnected the tertiary monitor, yanked the PCI video card, and started researching solutions. I thought I would have to upgrade to a dual PCI-X slot motherboard and run two video cards in an SLI/Crossfire configuration. That meant buying a new motherboard and a second GeForce 7600, and that would have been a pain in the ass for the former and a little difficult for the latter. The GeForce 7xxx series is now two or three generations old, and I didn’t want to gamble on a used card.
ATI’s new 57xx series features “Eyefinity,” which basically allows one card to aggregate several physical monitors into one meta-monitor. This is, conceptually, a little different from a multi-monitor display that breaks the desktop into several sections. Think of Eyefinity as making one big, oddly-shaped monitor out of whatever monitors you have on hand.
The trick to Eyefinity, however, is that you need at least one of those monitors to have a DisplayPort interface. I’d never even heard of this interface until I started researching the 57xx series. Apparently it’s on laptops and Apple has their own “mini” version of it. The problem was that my three existing Dell 22″ monitors had regular VGA and DVI.
I purchased a 22″ monitor from Dell with a DisplayPort link for about $240 shipped. I was surprised to see a shipping notification that evening, and the monitor showed up three days later. Problem solved, right?
Er, no.
