Given the affordability of high-res, big-screen displays, people are increasingly adopting multi-monitor setups for gaming and productivity. Although it's easier than ever to outfit your home office with several 27" screens, it wasn't long ago that such a setup required pricey specialized hardware. Nvidia released its TwinView dual-display architecture back in 2001 and ATI followed with HydraVision on the dual-head Radeon 7500 and 8500.Cheaply enabling more than two displays with a single card, however, is only a recent luxury for consumers. It wasn't until 2010 that ATI Eyefinity (now AMD-branded) shipped with the Radeon HD 5000 series, supporting three to six displays on one card. With Single Large Surface (SLS) technology, the cards can group together multiple monitors, which the operating system recognizes as a single ultra-high-resolution screen.
