Sharp recently sampled a few of their 32" 4K monitors to Microsoft's Extreme Windows. The blog, known for editorializing what enthusiasts can do with Microsoft products, combined three 3840 x 2160 monitors into a 3x1 Eyefinity configuration at 60 Hz; the screen, itself, measures about 7 feet diagonally. This configuration, unlike the already-supported three-display 30 Hz and single-display 60Hz 4K modes, required AMD to develop a customized driver before Sharp's repo-team reclaimed their $15,000 worth of monitors.

They had a day until their door was to be knocked.

The system, three Radeon HD 7970s in Crossfire, successfully drove... they were playing Dirt 3, by the way... the three monitors at 60 Hz with between 62 and 70, of software recorded, FPS. 11,520 x 2160, at 60 Hz, requires 1.5 billion colors to be calculated within a second of animation; that is 1.5 gigapixels. Ignore, for a moment, stutter caused by including Crossfire with an Eyefinity setup. Every calculation, whether properly drawn to the monitor or not is, and must be, performed; 1.5 gigapixels is impressive and an accomplishment for Radeon hardware.

Lastly, I need to call out drama as I see it: power supplies. It is not hard to find a PSU which can support a three-GPU system and no reason for it to be hanging outside the case. It might give off the bleeding-edge appearance, but this is not arc welding. If they really were concerned, they could have picked up a higher capacity device from the shelf of a local component reseller.

That's awesome, and borderline obscene :)

The article explains why they have the power supply outside of the case. It has nothing to do with the inability of finding a power supply that could power the system.

"This would be challenging as our case/motherboard was only setup to accommodate two cards, and we would need to install three cards (two double width, and one triple width). We both took a good look at the two gaming PCs we had on hand and decided that one of them may fit all three cards if we unbolted the power supply and pulled it out to make room for the 3rd card. "

Yep, thanks for the correction.

Haha actually the power supply did fail after 5 minutes. But the statement in your article is still inaccurate.

Yeah, if you look closely you can see that the lower card doesn't have the second screw installed as it's hanging into the space the PSU should be.

Just a flash in the pan- arc welding indeed!

wonder what the specs were on the PS- i am calculating a minimum of 625 needed at idle,

so a 750 is not really enough- get the cards all going and the power supply is going to shut down

Impressive!

It is probably also not very smart to keep the PSU in side of the case, in terms of cooling as well.

This is a drool-worthy setup! I just got a 760 and 2 more 22" monitors for a 3 screen setup and now it seems... anemic... small... weak, compared to that setup!

The only thing that sucks is that they chose Dirt3 which uses a lot of blur post effects and the screenshots don't look sharp, they look smudged and blurry.

Gavin Gear, the blogger who tested it, actually mentions that he was running the Eyefinity display at 30Hz because of the limitations imposed thanks to how Catalyst groups the monitors in tiled mode. The single monitor test was done at the full 60Hz with two HD7970s.
