Eyefinity 3 monitors, third not detected?

J-I-M · 17 Sep 2011 at 18:50

Hi everyone, i've just bought 2 Asus monitors to go with my third and planned on running 3 way monitor display, however i can only get 2 monitors to be detected by the card? I was told my overclockers I wouldn't need anything other than the monitors i bought and the ATI 6950, am i missing something? I've read about a display port or something however like stated above, i was told i would have everything i needed to run eyefinity?

To run three screens of a single ATI card, one of them must have a Displayport input.

Or you can use a "Active" Dispalyport-DVI adapter - http://www.sapphiretech.com/presentation/product/?cid=4&gid=1010&sgid=1011&pid=357&psn=&lid=1&leg=0

How are you trying to connect the three screens? exactly what card is it? it may have extra circuitry to not need any adapters just like a FLEX card - http://www.overclockers.co.uk/showproduct.php?prodid=GX-272-SP&groupid=701&catid=56&subcat=1752

It's very typical, as i did ask the technical support line of overclockers who are usually golden that i was not in need of any other devices which is ever so frustrating considering i paid an extra £30 to have the equipement delivered for the weekend - The card i'm using is this one http://www.overclockers.co.uk/showproduct.php?prodid=GX-273-SP&groupid=701&catid=56&subcat=1752

How have you connected the monitors to the card?

Chihero · 17 Sep 2011 at 20:18

How stulid said to do it with 1 connected to the display port with an Active adapter is how i do 3 screens with my 6870 the other 2 are DVI

the card you linked said its supplied with a mini display port to HDMI i assume the monitors dont have HDMI input?

J-I-M · 17 Sep 2011 at 20:19

Thanks for the reply - The 2 asus montiors i just bought yesterday both have 1 HDMI slot and 1 DVI and one VGA - Graphics card has 2 DVI 1 HDMI - 1 DP.

You must use an "active" adapter, theres nothing else you can do.

A "passive" adapter is no good as it wont run at HD resolutions.

There is this - http://www.overclockers.co.uk/showproduct.php?prodid=GX-249-SP&groupid=701&catid=56&subcat=1752 - but it says its a displayport to VGA. The other thing is its not found anywhere on the sapphire website. They only list the DVI version.

So basically i'm stuck with using a VGA display port? Must admit this really has ruined my weekend I have no idea why the technician on the end of the line told me I would need nothing other than what i purchased ;(

Maybe he didn't know the supplied adapter wasn't "Active" either way still sucks

J-I-M · 17 Sep 2011 at 20:29

I wasn't supplied with any adapter, only thing I got out of the graphics card was the card and a few cables.

stulid · 17 Sep 2011 at 20:30

Theres no other way, only the FLEX card can run multiple screens without adapters as it has extra circuitry on the card to do this (there is I think some ASUS card that can do a few screens also).

Or buy another 6950 for crossfire and then you can run a screen of the other card.

I would try and find the displayport to DVI version of that adapter.

Chihero · 17 Sep 2011 at 20:34

yer i have a Active display port to DVI - cant remember if i purchased it on this site or not.. i believe they did stock them at some point in the past

J-I-M · 17 Sep 2011 at 20:40

I believe so but they don't seem to anymore, and I've searched a few shops and it looks like i'll be waiting over a week for one to be delivered, really ruined my weekend.

I don't believe you can do that.

My understanding is that with Crossfire you can only use the outputs from one card.

You can use the outputs from a second card if they're not Crossfired but then that wouldn't be any use for Eyefinity.

I trust what you say, thought you could just like nvidia do it. If not then I know for next time.

I'll try and find the DVI Displayport adapter however everywhere i've found so far gives a rough estimate of 2 weeks delivery :mad:

Overclockers, why don't you blooming sell them! *Angry fist*

Trying putting "Sapphire Active Display Port to Single Link DVI Adaptor" into google shopping search...there's a well-known shop selling it at £17.49 with free delivery...and should take no more than a few days.

J-I-M · 18 Sep 2011 at 00:04

Thanks Marine, i'll give that a blast and see the what the outcome is.

You should consider this adapter: http://www.overclockers.co.uk/showproduct.php?prodid=GX-249-SP&groupid=701&catid=56&subcat=1866

Using one of these now and I see no image quality differences compared to DVI with my Eyefinity setup.
