AMD rolled out a reference-design DisplayPort to DVI active adapter today, that lets the masses create Eyefinity setups on existing monitors easier. The adapter plugs into full-sized and mini DisplayPort connectors on ATI Radeon graphics cards, and gives out a single-link DVI signal. The conversion between DP to DVI is active, and conserves video quality, as well as other features such as content protection. This is because when Eyefinity-ready graphics cards with DisplayPorts from AMD came to be, some manufacturers sold cheap $10 DP-DVI dongles that pass DVI signals from the DP directly (passive conversion). Such dongles more often don't work, because Radeon GPUs don't give out DVI signals from DP. Active adapters (those which actively convert DP signals to DVI) were sold at the time in upwards of $100.

AMD has managed to bring the price of such active adapters down to $30. There however, is a limitation. The output is a single-link DVI, meaning that it will support digital resolutions only up to 1920 x 1200 @ 60 Hz (1080p is supported). It shouldn't matter for the target users, because the DisplayPort on ATI Radeon HD 5000 graphics cards conveys only one TLDS link, so even with a DVI dual-link capable adapter, it would only give out single-link output. At least a bulk of the users are covered, at a very affordable price point. AMD will market this adapter directly, and through its growing network of add-in board partners (in bundles with graphics cards, or directly). PowerColor beat AMD to today's announcement, and released PowerColor-branded AMD-reference DP-DVI adapter last week.
