Wanna see what 24.5 million pixels looks like?

That’s six Dell 30″ displays, each with an individual resolution of 2560 x 1600. The game is World of Warcraft and the man crouched in front of the setup is Carrell Killebrew, his name may sound familiar.

Driving all of this is AMD’s next-generation GPU, which will be announced later this month. I didn’t leave out any letters, there’s a single GPU driving all of these panels. The actual resolution being rendered at is 7680 x 3200; WoW got over 80 fps with the details maxed. This is the successor to the RV770. We can’t talk specs but at today’s AMD press conference two details are public: 2.15 billion transistors and over 2.5 TFLOPs of performance. As expected, but nice to know regardless.

The technology being demonstrated here is called Eyefinity and it actually all started in notebooks.

Not Multi-Monitor, but Single Large Surface

DisplayPort is gaining popularity. It’s a very simple interface and you can expect to see mini-DisplayPort on notebooks and desktops alike in the very near future. Apple was the first to embrace it but others will follow.

The OEMs asked AMD for six possible outputs for DisplayPort from their notebook GPUs: up to two internally for notebook panels, up to two externally for conncetors on the side of the notebook and up to two for use via a docking station. In order to fulfill these needs AMD had to build in 6 lanes of DisplayPort outputs into its GPUs, driven by a single display engine. A single display engine could drive any two outputs, similar to how graphics cards work today.

Eventually someone looked at all of the outputs and realized that without too much effort you could drive six displays off of a single card – you just needed more display engines on the chip. AMD’s DX11 GPU family does just that.

At the bare minimum, the lowest end AMD DX11 GPU can support up to 3 displays. At the high end? A single GPU will be able to drive up to 6 displays.

AMD’s software makes the displays appear as one. This will work in Vista, Windows 7 as well as Linux.

The software layer makes it all seamless. The displays appear independent until you turn on SLS mode (Single Large Surface). When on, they’ll appear to Windows and its applications as one large, high resolution display. There’s no multimonitor mess to deal with, it just works. This is the way to do multi-monitor, both for work and games.

Note the desktop resolution of the 3×2 display setup

I played Dirt 2, a DX11 title at 7680 x 3200 and saw definitely playable frame rates. I played Left 4 Dead and the experience was much better. Obviously this new GPU is powerful, although I wouldn’t expect it to run everything at super high frame rates at 7680 x 3200.

If a game pulls its resolution list from Windows, it’ll work perfectly with Eyefinity.

With six 30″ panels you’re looking at several thousand dollars worth of displays. That was never the ultimate intention of Eyefinity, despite its overwhelming sweetness. Instead the idea was to provide gamers (and others in need of a single, high resolution display) the ability to piece together a display that offered more resolution and was more immersive than anything on the market today. The idea isn’t to pick up six 30″ displays but perhaps add a third 20″ panel to your existing setup, or buy five $150 displays to build the ultimate gaming setup. Even using 1680 x 1050 displays in a 5×1 arrangement (ideal for first person shooters apparently, since you get a nice wrap around effect) still nets you a 8400 x 1050 display. If you want more vertical real estate, switch over to a 3×2 setup and then you’re at 5040 x 2100. That’s more resolution for less than most high end 30″ panels.

Any configuration is supported, you can even group displays together. So you could turn a set of six displays into a group of 4 and a group of 2.

It all just seems to work, which is arguably the most impressive part of it all. AMD has partnered up with at least one display manufacturer to sell displays with thinner bezels and without distracting LEDs on the front:

We can expect brackets and support from more monitor makers in the future. Building a wall of displays isn’t exactly easy.
