ATI Eyefinity Multi-Monitors

Even at this low price point, ATI felt that people might want to take advantage of the new Eyefinity technology. Especially if you look at this product as an upgrade part for someone with OEM or IGP video, they can add a second monitor at the same time and really improve their gaming and HD video experience.

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 superhigh resolution gaming and entertainment, and enabling easy configuration. High end editions will support up to six independent display outputs simultaneously.

In the past, multi-display systems catered to professionals in specific industries. Financial, energy, and medical are just some industries where multi-display systems are a necessity. Today, more and more graphic designers, CAD engineers and programmers are attaching more than one display to their workstation. A major benefit of a multi-display system is simple and universal - it enables increased productivity. This has been confirmed in industry studies which show that attaching more than one display device to a PC can significantly increase user productivity.

Early multi-display solutions were non-ideal. Bulky CRT monitors claimed too much desk space; thinner LCD monitors were very expensive; and external multidisplay hardware were 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 I/O pins from the GPU. It was clear that a superior display interface was needed.

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 provides the clock signal needed to drive as many DisplayPort display devices as there are display pipelines in the GPU. In addition, with the same number of I/O 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 immersive graphics and computing experience, supporting massive virtual 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. 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 be a key enabler for multi-display technology, and AMD will be at the forefront of this transition.

is ATI Radeon HD5450 compitable with intel dual core 2.8 Ghz processor ?
Please reply as early as possible

Yes. All video cards are compatible with all processors. Just make sure the motherboard has a PCI-Express graphics slot.

Wikipedia has some good pictures on the PCI Express page that show what they look like

This card is on the low end of discrete graphics.
It's really better suited to a Home Theater PC.

# Fan connectorRoger 2012-06-01 17:01
I see there is what looks like a fan connector on the card - is this correct and if so what would be the power specs for a fan?

If you look at some of the other HD 5450 cards out on the market (Newegg has 34 models for sale, 2+ years after launch...!) you wll see that many of them have active cooling, with a fan plugged into this very same header. It's only two pins, so don't expect PWM or anything, just straight DC with no speed monitoring.

The PCI slot has to have the little gap thing, the oppisite way around that does the graphics card have so for instance -- ---- and ---- -- and most of all if the the ports on the graphics card are pointing toward the outside, etc.

# Re Fan ConnectorRoger 2012-06-02 18:10
Thanks for that Bruce,

Just to clarify such a connected fan would be of similar size and watts etc. to an inbuilt one?

Like I have a spare fan DC 12v 0.11A which is probably ok and another which is DC 12v 0.70A which is probably too powerful?

# Yes, again....Bruce 2012-06-03 06:58
That's the idea. It's not going to be an exact science, but most fans that are small enough and thin enough to fit on that card's heatsink will be fine. I've been assuming that you want to cool the GPU on the HD 5450 with this fan... right?

# Thats right Bruce...Roger 2012-06-03 22:01
I figure one cannot have enough fans (especially where I live in the tropics) so I might as well use a spare fan to play on the heatsink. The card will be on the bottom of the mobo with the heat sink facing down so I will mount the fan on the case bottom facing up to the heatsink.

Thanks again

I badly needed an htpc graphic card for my htpc. I am really having a hard time choosing because i really don't have any idea with these kind of things. But anyways, you're post is quite helpful. Thanks!

It is not good for high resolution games.
It was designed for HTPC use, which is much less demanding.
Plus, it was released three years ago, that's a LONG time in video card history. Why are you interested in it now? Can you even buy one in your location?
