HDMI's half-brother, DisplayPort is the connector to replace the aging DVI (not to mention D-Sub) so ELSA though it should back it up properly. Going a bit to the extreme but still following Nvidia's reference design, ELSA has introduced the Quadro NVS 450 professional card which, as seen below, has only DisplayPort connectors - four of them.
Able to provide pixels for up to four 30-inch displays, the card has two GPUs clocked at 480 MHz, a total of 16 Stream Processors, 512MB of GDDR3 set to 1400 MHz and a 64-bit memory interface. The Quadro NVS 450 resorts to a passive cooling system, has a PCI-Express x16 interface and, of course, features DirectX 10 support. Als, for those in need, ELSA is bundling the card with a DisplayPort to DVI adapter.
