For example, when a DVI-to-VGA converter is attached to a DVI port). The display controller has two RAMDACs that drive the VGA or DVI ports in analog mode.
The Radeon HD 5870 Eyefinity Edition, however, supports six mini DisplayPort outputs, all of which can be simultaneously active. The entire HD 5000 series of products have Eyefinity capabilities supporting three outputs.
This external clock is what allows Eyefinity to fuel up to six monitors from a single card. But all displays connected over DisplayPort can be driven from only one external clock. Displays connected over VGA, DVI, or HDMI each require their own internal clock. The HD 5000-series designs host two internal clocks and one external clock. Overview ĪMD Eyefinity is implemented by multiple on- die display controllers. The version of AMD Eyefinity (aka DCE, display controller engine) introduced with Excavator-based Carrizo APUs features a Video underlay pipe. The setup of large video walls by connecting multiple computers over Gigabit Ethernet or Ethernet is also supported. Alternatively active DisplayPort-to-DVI/HDMI/VGA adapters can be employed. To feed more than two displays, the additional panels must have native DisplayPort support. ĪMD Eyefinity supports a maximum of 2 non- DisplayPort displays (e.g., HDMI, DVI, VGA, DMS-59, VHDCI) (which AMD calls "legacy output") and up to 6 DisplayPort displays simultaneously using a single graphics card or APU.
AMD Eyefinity was introduced with the Radeon HD 5000 Series "Evergreen" in September 2009 and has been available on APUs and professional-grade graphics cards branded AMD FirePro as well.
