The Apple Cinema 30-inch display was among the first monitors to have the WQXGA resolution, and at that time in 2004, dual-link DVI was uncommon even in desktop computers, much more those that had two dual-link DVI ports. Apple had to partner with Nvidia in order to develop a special AGP graphics card with two dual-link DVI ports able to drive two 30-inch Apple Cinema displays. This add-on card could be installed in the large desktop Macs such as the Power Mac G5.
