AMD's Eyefinity Technology Explained

Screen Groups

What sort of display arrangements can you make with Eyefinity? You can use the Duplicated (cloned) mode to copy one desktop onto multiple screens. Laptop users do this all of the time for presentations. Alternatively, Extended mode lets you span one workspace across multiple screens, a grouping AMD calls a “single large surface.”

At its simplest, Eyefinity lets you do basic dual-screen setups, just as you would with a traditional dual-output card. Screens can be set in 2x1 landscape, 2x1 portrait, or 1x2 landscape. Interestingly, AMD kept its eye on streamlining the user experience without limiting reasonable options. For instance, you won’t find a 1x2 portrait group configuration because there’s no common use scenario that supports such a tall, narrow display. Why clutter up the configuration UI with an option for it? The same three orientations apply for triple-screen viewing: 3x1 landscape, 3x1 portrait, and 1x3 landscape.

Stepping up to four monitors, there are only two configurations offered: 4x1 landscape and 2x2 landscape. When you see shots such as the 3x1 portrait Battle Forge example, you have to wonder, “OK, why not 4x1 or 5x1 portrait?” Apparently, AMD’s research led them to decide that the number of people who might use such a mode didn’t justify including the option in the driver. And curiously, there actually are no five-screen modes.

For six monitors, there is only the 3x2 landscape option.

Now, what we’ve described here are your options for “display groups.” You can also create “Extended” groups. These are essentially separate desktop spaces that can run alongside your primary display group. You can see some examples in the image below. You might have a 3x1 portrait display group of 24" displays on your desk but have a separate 19" extended screen mounted to your wall for messaging apps and perhaps another 15" extended screen (making three groups total) for showing system temps, fan speeds, overclocking tools, and so on.

The theoretical maximum for today’s Eyefinity technology specs a maximum 8192x8192 (67.1 megapixels) resolution, figuring six 2560x1600 panels.
