TUL Embedded : Graphics, VGA

AMD Eyefinity is a multi-display technology that allows multiple displays to appear as a large surface spanning many panels or to run up to six simultaneous displays off of a single graphics card .
More importantly for users, AMD Eyefinity technology is not a feature we reserve for our most expensive products. Indeed, AMD Eyefinity technology is available on more than 45 professional-grade products. These products cover a very large spectrum of prices, giving you the flexibility to find the valuable solution that you need.

Every Eyefinity GPU series supports a different maximum number of displays. This support is inherent to the AMD graphics chip at the heart of your graphics card. Before looking through the table, though, keep in mind that the maximum number of supported displays can differ from the number of display outputs on the card. Certain adapters, hubs, or a non-reference graphics card may be required to take full advantage of the capabilities we build into our chips.

In traditional multi-monitor setups, any piece of an object moving from one monitor to the next is simply chopped off and moved, regardless of how small that piece may be. For example, a small piece of a character’s armor might reach the edge of one display, resulting in the armor appearing to “jump” crudely to the next display. This chopping may also cause objects to become misaligned as they pass between displays.

That piece of armor on the next display may be positioned higher or lower than the player would expect it to be, and that effect can compromise the immersion of the game. Bezel compensation remedies these issues by treating the plastic frame of your displays as an object that games and applications merely pass behind. The effect is subtle, but impressive: objects are no longer interrupted by the bezel, and remain aligned when passing from one display to the next.

A passive adapter is the most basic type of adapter that can purchased. A passive DisplayPort adapter merely allows the GPU to communicate with a “language” that can be understood by the attached monitor, which has a differing connector.
As an example, using a passive adapter to connect a DVI monitor to a GPU’s DisplayPort connection will essentially cause that DisplayPort output to communicate with the “language” of DVI. As far as the GPU is concerned, it does not have a DisplayPort monitor connected, and therefore cannot leverage the benefits that DisplayPort enables (e.g. AMD Eyefinity technology).
In contrast, active adapters will actively translate the DVI signal coming from the monitor into a native DisplayPort signal for the GPU (and vice versa). A native DisplayPort signal is required for AMD Eyefinity because DisplayPort signals can be synchronized by the GPU to keep all of your monitors moving in concert.
This DisplayPort signal can also be synchronized with DVI and HDMI signals, but only two of these signals may be utilized on an AMD Radeon™ GPU. This is why AMD Eyefinity technology requires a native DisplayPort signal for the third (or higher) monitor. What features of AMD Eyefinity technology are supported in the different versions of Microsoft® Windows®?

The display engine built into the HD 5000 & 6000 series is capable of generating two concurrent digital outputs with timing, and one DisplayPort output. DVI and HDMI signals need timing and centering information for the displays to work. Without this information, the screen can't sync properly, and the display will fail to show correctly, if at all. Passive DisplayPort adapters don't generate the timing signals required for the DVI or HDMI display, and so won't work for Eyefinity.
AMD E6760 series needs to use passive DisplayPort adapters (mini-DP to DP, mini-DP to DVI or mini-DP to HDMI). If you have more than two displays that don't support a native DisplayPort connection you'll need additional, active, adapters.

Previously ATI Eyefinity forced all displays in an Eyefinity group to be the same orientation and resolution. As of AMD Catalyst 11.10 you can officially run dissimilar monitor sizes.
For the AMD Radeon HD 5000 series, the Single Large Surface is limited to a maximum resolution of 8000 pixels in any one axis, and a maximum of 5 displays (portrait or landscape, using Catalyst 11.10 or later). On the AMD Radeon HD 6000 series, the maximum SLS is 16000x16000, for DX11; DX9 and DX10 will not permit this size, meaning Aero desktop will need to be disabled and only DX11 mode games will use the full resolution size.
If you use displays of different sizes and resolutions, the resulting AMD Eyefinity group will be limited to the highest common resolution of the displays on all panels. If you have two 22" 1920x1080 displays and a 24" 1920x1200, all three will run in 1920x1080.

Vision Engine Control Center profiles support AMD/ATI Eyefinity groups, so that you can set up multple settings with active panels and resolutions. Bezel compensation and panels being enabled/disabled are included in these settings.

To have ATI Eyefinity work, you need Windows 7, Windows 8 OS, and Display Port monitor.

If you are using any dongle on DVI or VGA monitors, the dongle needs to be an Active one, a passive dongle does not work.
