Driving two monitors is easy enough with most modern videocards; in fact, late-model AMD Radeon HD cards can drive three (although one must be equipped with DisplayPort). Accell’s UltraAV multi-monitor adapters allow you to connect three displays to a single DisplayPort source. The model we examined supports three single-link DVI monitors using a single DisplayPort source; the company offers a second SKU that supports three DisplayPort monitors from a single DisplayPort. Both suffer from the same limitations: Reliance on DisplayPort on the host side, and maximum resolution of 3840x1024 (supporting three 1280x1024 displays).
