AMD Eyefinity is the brand name of AMD's on-die multi-monitor-display controllers which support to drive at least three and up to six simultaneous displays off of a single graphics card.[1] AMD Eyefinity was introduced with the Radeon HD 5000 Series in September 2009. AMD Eyefinity is available on more than 45 consumer as well as AMD FirePro professional-grade products.[2]

All AMD GPUs newer the the Evergreen support maximum of 2 non-DisplayPort displays and a maximum of 6 DisplayPort displays.[3]

There is the additional possibility to connect multiple computers over Gigabit Ethernet or Ethernet to drive a large video wall.[4]

Overview

The 5000-series designs host two internal clocks and one external clock. Displays connected over VGA, DVI, or HDMI each require their own internal clock. But all displays connected over DisplayPort can be driven from only one external clock. This external clock is what allows Eyefinity to fuel up to six monitors from a single card.

The entire HD 5000 series products have Eyefinity capabilities supporting three outputs. The Radeon HD 5870 Eyefinity Edition, however, supports six mini DisplayPort outputs, all of which can be simultaneously active.[5]

The display controller has two RAMDACs which are used to drive the VGA or the DVI ports in analog mode (for example, when a DVI-to-VGA converter is attached to a DVI port), a maximum of six digital transmitters that can output either a DisplayPort signal or a TMDS signal which is used for either DVI or HDMI, and two clock signal generators needed to drive the digital outputs in TMDS mode. Dual-link DVI displays use two of the TMDS/DisplayPort transmitters and one clock signal each. Single-link DVI displays and HDMI displays use one TMDS/DisplayPort transmitter and one clock signal each. DisplayPort displays use one TMDS/DisplayPort transmitter and no clock signal.

An active DisplayPort adapter can be used to convert a DisplayPort signal to another type of signal like VGA, single-link DVI or dual-link DVI, or HDMI if more than two non-DisplayPort displays need to be connected to a Radeon HD 5000 series graphics card.[5]

DisplayPort 1.2 added the possibility to drive multiple displays on single DisplayPort connector, called Multi-Stream Transport (MST). AMD graphics solutions equipped with DisplayPort 1.2 outputs can run multiple monitors from a single port.

At High-Performance Graphics 2010 Mark Fowler presented the Evergreen and stated that e.g. 5870 (Cypress), 5770 (Juniper) and 5670 (Redwood) support max resolution of the 6 times 2560×1600 pixels, while the 5470 (Cedar) supports 4 times 2560×1600 pixels.[6]

The entire Radeon HD 5000 Series and Radeon HD 6000 Series. The exact technical specifications of the Radeon HD 5870 look as follows:[7]

  • DisplayPort 1.2 with a max resolution of 2560×1600 per display, MST, 21.6 Gbit/s bandwidth, high bit-rate audio
  • dual-link DVI output with HDCP and a max resolution of 2560×1600
  • HDMI (with 3D, Deep Color and x.v.Color) with a max resolution of 1920×1200
  • VGA with a max resolution of 2048×1536 pixels

The entire Radeon HD 7000 Series:

  • DisplayPort 1.2 maximum resolution of 4096×2160 @ 60 Hz per display, MTS, 21.6 Gbit/s bandwidth (HBR2), high bit-rate audio, quad HD/4K/UHDTV display support, 1080p60 stereoscopic 3D (Frame Sequential Format)
  • Dual-link DVI with HDCP Maximum resolution: 2560×1600
  • HDMI (With 4K, 3D, x.v.Color™ and Deep Color) a maximum resolution of 4096×2160 @ 30 Hz, 1080p30 stereoscopic 3D (Packed Frame Format), Quad HD/4K/UHDTV video display support
  • VGA with a max resolution of 2048×1536 pixels

The AMD Radeon Rx 200 Series all have support for (4K@60 Hz SST or MST)

Software support

AMD Catalyst supports Eyefinity and enables the user to independently configure and run each attached displays. It facilitates the configuration of "cloned mode", i.e. to copy one desktop onto multiple screens or "extended mode", i.e. to span the workspace across multiple screens and combine the resolutions of all of those displays into one big resolution. AMD calls the extended modes Single Large Surface (SLS) and Catalyst support of certain range of display group configurations. For example 5x1 landscape and 5x1 portrait are supported since AMD Catalyst version 11.10 from October 2011.[2][23]

Starting in Catalyst 14.6 AMD has enabled mixed resolution support, allowing for a single Eyefinity display group to be created while each monitor runs at a different resolution. This feature is made possible through the addition of two new Eyefinity display modes, Fit and Expand, which join the traditional Fill mode. In both Fit an Expand mode AMD is compensating for the mismatched resolutions by creating a virtual desktop that is of a different resolution than the monitors, and then either padding it out or cropping it as is necessary.[24]

AMD validated some video games to support Eyefinity. The short list include titles such as Age of Conan, ARMA 2: Operation Arrowhead, S.T.A.L.K.E.R.: Call of Pripyat, Serious Sam 3: BFE, Singularity (video game), Sleeping Dogs, Assassin's Creed II, Sniper Elite V2, Soldier of Fortune Online, Tom Clancy's Splinter Cell: Conviction, Star Wars: The Force Unleashed 2, Marvel Super Hero Squad Online, R.U.S.E., Supreme Commander 2 among others.[25] However, game not on this short list seem to work as well, e.g. Dirt 3 and The Elder Scrolls V: Skyrim.
