In 2004 a new line was introduced, utilizing the same 20″ and 23″ panels alongside a new 30″ model, for $3,299. The displays had a sleek aluminum enclosure with a much narrower bezel than their predecessors. The 20″ model featured a 1680×1050 resolution, the 23″ 1920×1200, and the 30″ 2560×1600. The 30″ version requires a dual-link interface, because a single-link DVI connection (the most common type) doesn't have enough bandwidth to provide a picture to a display of this resolution. Initially, the only graphics cards that could power the new 30″ display were the Nvidia Geforce 6800 DDL series, available in both GT and Ultra forms. The DDL suffix signified the dual-link DVI capability. The less expensive of the two cards retailed for US$499, raising the net cost of owning and using the display to nearly $3,800. Later graphics options included the NVIDIA Quadro FX 4500; the card included two dual-link DVI connectors which allowed a Power Mac G5 to run two 30″ Cinema Displays simultaneously with the total number of pixels working out to 8.2 million.
