The compact size lets a low-profile card support two high resolution displays, and a full-height card (with two DMS-59 connectors) up to four high resolution displays. The DMS-59 connector was used by e.g. AMD , Nvidia and Matrox for video cards sold in some Lenovo ThinkStation models, Viglen Genies and Omninos, Dell, HP and Compaq computers.
