ATI Eyefinity Multi-Monitors

ATI Eyefinity advanced multiple-display technology launches a new era of panoramic computing, helping to boost productivity and multitasking with innovative graphics display capabilities supporting massive desktop workspaces, creating ultra-immersive computing environments with super-high resolution gaming and entertainment, and enabling easy configuration and supporting up to six independent display outputs simultaneously.

In the past, multi-display systems catered to professionals in specific industries. Financial, gas and oil, and medical are just some industries where multi-display systems are not only desirable, but a necessity. Today, even graphic designers, CAD engineers and programmers are attaching more than one displays to their workstation. A major benefit of a multi-display system is simple and universal - it enables increased productivity. This has been demonstrated in industry studies which have shown that attaching more than one display device to a PC can significantly increase user productivity.

The early multi-display solutions were non-ideal. The bulky CRT monitors claimed too much desk space, thinner LCD monitors were very expensive, and external multi-display hardware was inconvenient and also very expensive. These issues are much less of a concern today. LCD monitors are very affordable and current generation GPUs can drive multiple display devices independently and simultaneously, without the need for external hardware. Despite the advancements in multi-display technology, AMD engineers still felt there was room for improvement, especially regarding the display interfaces. VGA carries analog signals and needs a dedicated DAC per display output, which consumes power and ASIC space. Dual-Link DVI is digital, but requires a dedicated clock source per display output and uses too many IO pins from our GPU. If we were to overcome the dual display per GPU barrier, it was clear that we needed a superior display interface.

In 2004, a group of PC companies collaborated to define and develop DisplayPort, a powerful and robust digital display interface. At that time, engineers working for the former ATI Technologies Inc. were already thinking about a more elegant solution to drive more than two display devices per GPU, and it was clear that DisplayPort was the interface of choice for this task.

In contrast to other digital display interfaces, DisplayPort does not require a dedicated clock signal for each display output. In fact the data link is fixed at 1.62Gbps or 2.7Gbps per lane, irrespective of the timing of the attached display device. The benefit of this design is that one reference clock source can provide the clock signals needed to drive as many DisplayPort display devices as there are display pipelines in the GPU. In addition, with the same number of IO pins used for Single-Link DVI, a full speed DisplayPort link can be driven which provides more bandwidth and translates to higher resolutions, refresh rates and color depths. All these benefits perfectly complement ATI Eyefinity Multi-Display Technology.

ATI Eyefinity Technology from AMD provides advanced multiple monitor technology delivering an incredibly immersive graphics and computing experience with innovative display capabilities, supporting massive desktop workspaces and super-high resolution gaming environments. Legacy GPUs have supported up to two display outputs simultaneously and independently for more than a decade. Until now graphics solutions have supported more than two monitors by combining multiple GPUs on a single graphics card. With the introduction of AMD's next-generation graphics product series supporting DirectX 11, a single GPU now has the advanced capability of simultaneously supporting up to six independent display outputs.

ATI Eyefinity Technology is closely aligned with AMD's DisplayPort implementation providing the flexibility and upgradability modern user's demand. Up to two DVI, HDMI, or VGA display outputs can be combined with DisplayPort outputs for a total of up to six monitors, depending on the graphics card configuration. The initial AMD graphics products with ATI Eyefinity technology will support a maximum of three independent display outputs via a combination of two DVI, HDMI or VGA with one DisplayPort monitor. AMD has a future product planned to support up to six DisplayPort outputs. Wider display connectivity is possible by using display output adapters that support active translation from DisplayPort to DVI or VGA.

The DisplayPort 1.2 specification is currently being developed by the same group of companies who designed the original DisplayPort specification. This new spec will include exciting new features for our customers. Its feature set includes higher bandwidth, enhanced audio and multi-stream support. Multi-stream, commonly referred to as daisy-chaining, is the ability to address and drive multiple display devices through one connector. This technology, coupled with ATI Eyefinity Technology, will re-introduce multi-display technology and AMD will be at the forefront of this transition.

# the diffrenceJeff 2010-03-24 07:12
In my opinion. the diffrence between ATI and NVidia when it comes to gameing, is that NVidia seems to have alot of technical problems and games seem to crash every so often. With ATI the video card drivers and software can be more user friendly. the cards are outstanding in the performance and there are no problems when it comes to games, movies, etc. The best part of ATI, is Eye Finity.... Hopefully they can come up with a card that can hold the 3 screens, but dont have to order a dual link to DVI adapter off the internet... which seems to be the biggest problem for most people....

# Drivers Blow !!!Mike 2010-03-26 17:01
ATI's drivers are horrendous!! I have had nothing but problems with them. Tons of in game glitches and outright crashes and they are never optimized when a new game is released. It takes forever for them to address individual game issues ( see Batman Arkham Asylum and AA ). They might release a driver a month but I think all they do is change the version number and kick it out the door. If you really want bad drivers just run any of their 2x gpu cards then it gets even worse...

Jeff sounds like ATI employee at the very least.

# ... So Does Mike ;)EetMe 2010-04-10 09:59
ATI is clearly the "hardware" king-o-graphics/GPU's right now. Mike sounds like a poor-loser nv-fanboy. tough eh ?

I still don't get why people complain about ATI's drivers. I keep up to date monthly and sometimes much longer periods before I do update, and I haven't had a single issue. Yeah, the games have crashed but hell, they did that to me back in 95. Learn how to keep your drivers in shape newbies, as I've yet to experience anything overly frustrating in this many years of ATI.

# ATI and NVIDIA both have issues.Olin Coles 2010-05-03 16:07
I've already pointed out problems with NVIDIA drivers here: benchmarkreviews.com/index.php?option=com_content&task=view&id=194
What I haven't pointed out is how NVIDIA drivers lack 60Hz support, and instead offers a lower 59Hz option. On the other hand, ATI delivers the full 60Hz experience, and Battlefield Bad Company 2 loads levels in only 10 seconds and not 62 like the latest Forceware driver. As I see it right now, ATI has an edge over NVIDIA drivers.

I'm unsure if Mike understands how to correctly install the drivers for his GPU. The only time I've ever had issues with my 5970 is when USER error was involved. Yes I am human too. haha. If you are switching from Nvidia or if you wish to have a clean install use a product like Driver Sweep. Download the newest drivers from ATI first. Run Driver Sweep and remove the ATI drivers. For an extra layer of assurance uninstall your video drivers/hardware in safe mode as well, re boot and install the new drivers!! Easy cheesy! :-)

# Not 1 single problemRecon 2010-08-06 10:19
I have buy this card. And i love nv (always buy Nividia). But i was afread bugged drivers because i have see so many bad reviews its like the trying to rip off ati, however a friend buy this card. And i was like OMFG this can not be happening, Well see that beast in action i can not belive wat that thing can do. So i buy this card. So far not even 1 single crash. Perhaps people need to chill down and buy this card. Realy the love it when the have this card. If ati stay that way i will follow.

Uh well my HIS HD4870 has major problems. Actually, I have two of them and they both exhibit the same problems. I can't even run MOH:AA without cat A.I. on at least low. Took me about 2 years to figure this out, so I went 2 years without playing one of all time favorite classic games. No one had an answer, including ATI. I also can't play the game with Vsync on, or my mouse becomes erratic. This does not happen on ANY other video card I've had, but does with both HD4870s. Add to this numerous other glitches and I've pulled all of my hair out over it the past couple of years. I don't know if this is a hardware issue with this particular model of card, or a driver issue, or both. I just hope, really hope that if I spend another 400 dollars on my next ATI card that I do not have these glaring issues.

# Ati Vs NvidiaRoy 2010-10-08 13:35
i always used to have an Nvidia card, but now it was time to change to an Ati card.
Ati has the best ones at this moment in my eyes.
i just bought an Sapphire Hd 5850 Toxic, it runs great, silence and it doesnt gets hot.

If you wanna buy an new graphics cards, then buy an ati, there the best now.
(ati is the cheapest and it wont use as much power as an nvidia as well atm)
