Multiple monitor gaming and usage has been around for many years with dual displays being at the heart of video cards since the advent of the Riva TNT2 cards way back in 1999. 3 monitor gaming was introduced with the Matrox Parhelia graphics card in 2002 with a feature called Surround Gaming. AMD introduced the RADEON HD 5xxx series last year and it features 3-monitor gaming on every card.
You’ll notice that I said AMD instead of ATI. In the upcoming product refresh AMD will not be using the ATI brand going forward. As the merger of AMD and ATI happened over 3 years ago it only makes sense to unify the branding of the graphics chips under the AMD name. After all, you wouldn’t call a McDonnell Douglas MD-95 that after the Boeing/McDonnell Douglas merger it would be a Boeing 717. AMD similarly will call their next refresh AMD Graphics instead of ATI Graphics.
One of the issues with the HD 5xxx series is that to use three or more monitors Display Port needs to be supported. Today Sapphire is announcing the RADEON HD 5770 Flex Edition card which has the ability to run three DVI monitors in Eyefinity mode, or four monitor mode with the Display Port connector. This brings added flexibility to a card that supports three monitors or even six monitors if there are enough Display Port connections and monitors. The Sapphire HD 5770 Flex Edition card is what is on the review bench today.
