SAPPHIRE Solves Eyefinity Issue with Active DisplayPort Adapter

[FordGT90Concept]

I'm trying to show why the two need separate, but compatible standards. Monitors are intended for a viewing distance of less than 2 feet where TVs are designed for 6+ feet. In order to get a good picture at less than two feet away, you need a really high resolution (dpi). Conversly, the farther away you get from the display, the lower the dpi necessary to make it look exactly the same to the eye. More DPI means more bandwidth and more bandwidth means more robust cables. I think it is a bad idea to attempt to merge the two. I mean, HDMI is just now getting market acceptance when DVI has been around a long time.

HDMI is good to go in the entertainment industry but it is time for the computer industry to move on. HDMI is old for that segment of the market.

your argument holds flawed logic.

since keyboards and mice dont need the bandwidth of USB and are designed for different things than flash drives, they should go back to PS/2 connectors - its been around longer.


Fair enough that you have your own opinion (dont care about HDMI) but your logic contradicts precendents - people prefer one unifying standard even if it does limit them slightly. its better than everyone having their own incompatible standards.

There are no choices anymore. You plug it in and the equipment tells everything connected what it is allowed to do regardless of what you, the consumer, actually want. This is just getting plain silly. Before long, you won't be able to do anything without signing a contract and connecting it to the Internet with which, they see, hear, and whatever else they conjure up without you having any authority beyond installing the equipment or not (and we know people would blindly agree--end justifies the means). The door is wide open to that doom's day prophecy with DisplayPort and once that door is open, it won't close.

Are you honestly surprised? What did you expect?

i agree with GT90Concept

 

[FordGT90Concept]

You know how a keyboard works, right? It has a series of interrupts and each key is assigned to a specific interrupt group. PS/2 is practically the same as USB in terms of wiring. If PS/2 were replaced with a new cable which supports one interrupt per key, there would never be a problem with interrupt collisions again. Instead of improving the keyboard connector, we threw it into a trash bin with all the other flawed connection standards.

Mice don't need as many interrupts as keyboards so more suitable connector than USB would be difficult to come by--unless something revolutionary happened.


The advantage of PS/2 mice and keyboard is that, if they plug in, you can be guaranteed they work so long as they aren't defective.

Fair enough that you have your own opinion (dont care about HDMI) but your logic contradicts precendents - people prefer one unifying standard even if it does limit them slightly. its better than everyone having their own incompatible standards.

Standards = compatibility.

Are you honestly surprised? What did you expect?

I'm not surprised, no. It should be illegal to develop such standards (business, not consumer interest) internationally.


Edit: The USB hub often isn't initialized soon enough. For example, my DFI LP X58 motherboard doesn't initialize the USB hub until an OS is loading. This means that, with an USB keyboard, the BIOS are not accessible. I have to plug in a PS/2 keyboard (which is initialized before POST begins) in order to access the BIOS. Yet another reason why keyboards need their own dedicated cable, connectors, and protocols.

PS/2 can do full n-key rollover. USB cannot.

 

[Hayder_Master]

its one display port to one DVI port - the other plug is USB for power.

To be honest, this does confuse me.

With 2x DVI, 1x HDMI and 1x DP, i dont see why users cant use a HDMI to DVI adaptor/cable for eyefinity without needing this expensive adaptor.

Is there some limitation with one of those DVI ports not working if the HDMI port is in use?

thanx for info

 

[Munchy]

Excellent i have found people that actually know what they are on about,

I have been through this saga on several forums now and wondered if anyone can kick me in the right direction,

i have HD5870

3 monitors all working

2 x dvi and 1 passive display port adapter to dvi

now i can only use 2 @ a time so is this really because i need the expensive adapter?

Please do note i do not want extended desktop i only want monitor one and monitor two in extended mode and monitor three mirroring monitor 2

i figured as it is actually working on all three monitors (only 2 at a time) there must be a way to use 3 at the same time.

lol i know my answer but i just need someone to shout it at me so i believe them.

i feel a little hard done by shelling out 220 on the card and then another 80 is for the adapter.

ps has anyone seen the active converters for sale anywhere?

Edit,

new train of thought?

Seeing as the passive dp to dvi is working is it possible that they wont all duplicate due to the third monitor being a different size?

 

[jagd]

Correct you need active adapter for 3rd monitor http://www.amd.com/us/Documents/ATI_Eyefinity_Technology_Brief.pdf download pdf and read 7th and 8th pages

Read directly from Dave Bauman ( product manager of AMD/ATI )

Munchy i wish you had been written where are you living ,you can find DELL/blizzlink adapters at US and accell and sapphire adapters at Europe ,i gave a link to accell adapter at first page from a netherland company (accell = blizzlink ,retail brand according to info i found )

and all three monitors must be the same resolution, thats another requirement

and 1920x1080 max correct? Or can all 3 be run @ say 2048x1152.

i didnt see a max res, but that doesnt mean there isnt one

 

[FordGT90Concept]

The safest max res would probably be 1920x1200 @ 60 Hz (single-link DVI). It might be able to go to dual-link DVI res (2560×1600 @ 60 Hz) but don't count on it.

 

[jagd]

of course it is possible , ati demoed eyefinity on 2560* 1600 (3 monitor = 7680* 1600 and 6 monitor = 7680 *3200 config ) there are alot reviews with 2560*1600.

Sweet, im glad to hear it. Does anyone know if you can still rotate monitors when using eyefinity? I have not seen anything about that either.

since they all need the same resolution, they'd all have to have the same orientation

 

[GSG-9]

Yes but they can all be rotated 90 degrees, which you can imagine results in a completely different aspect ratio. The Triple Head 2 Go could do this, thats the only reason I ask.

Before eyefinity can be used for gaming, xfire must be supported. No way 1 graphics card can game great at 7860*1600. you almost need xfire/SLI even for 2560x1600.

 

[Disparia]

That support came with the 9.12 Hotfix drivers.

Haven't seen anyone here post their experience, but over at WidescreenGamingForum and HardOCP some people have posted that it is working. No benches yet.

If that's the case, thats awesome. I wonder if it's possible to use the DVI or HDMI on the
2nd or 3rd video card? or is it not physically possible..

Rotating monitor support?

 

[Disparia]

I think that support has been there since 9.10 (when Eyefinity got support):

[bryantalpinerunner]

Please Help!! Almost Got It!!!

PLEASE HELP!!! I bought the EFX version of ATIs 5670 Card. As you know it had DVI HDMI and Displayport, so without the active adapter i couldnt have all 3 monitors simotaeously. I found Saphires version of the same 5670 card ony difference is it had DVI HDMI and VGA! i thought i found a loophole and wouldnt need the active adapter. After installing the card and the driver it came with, im still have the same issue requiring me to disable one of my monitors to use the 3rd one! NOW IM REALLY UPSET! If anyone has any solution or explanation for this i would really appretiate it!! Thanks in advance - Bryant

 

[Mussels]

the models with VGA dont support eyefinity - only two screens will work.

Thanks for the info i knew it was too good to be true. Could anyone suggest the cheapest place to get the active display port adapter thats been confirmed to work?
