NVIDIA recently unveiled its newest video card which fits SFF PCs. It's the Quadro NVS 420 which can support 4 30 inch (high-resolution) displays at a resolution of 2560 x 1600. This card was designed with the office in mind by giving workers more desktop, "real estate" to work with.
Additional features of the NVIDIA Quadro NVS 420 include:
NVIDIA nView display software, which allows users to spread their work across single, large or multiple displays and maximize productivity through user friendly desktop and application management features:
Display gridlines for maximizing a user’s desktop space by dividing up the displays into multiple regions
Virtual desktops that allow users to launch applications on up to 32 different desktops
Extended Windows Taskbar spans across multiple displays so the application window buttons can be spread over multiple displays
Early reports say that the product, when released, will cost around $400.
