This is with a proper DP to DVI 'Active' dongle?

For 3 DVI-derived ports, you will need an active DisplayPort-to-DVI adapter.

A couple of notes on these outputs - if you already have some DVI-ready monitors and are looking forward to triple monitor support you might be disappointed to learn that the DisplayPort connection requires an ACTIVE adaptor to be converted to a DVI connection. The adaptors are also expensive (around $100) and are pretty hard to find right now. AMD says they are trying to address this but short of selling their own version I am not sure what pull they have in this regard. Converting from dual-link DVI to DisplayPort, if you have more than one DisplayPort monitor, is a much easier task and only requires a less expensive passive adaptor.

Aha, now we have that pic! If you look at that adapter, you'll see it isn't just a simple DisplayPort -> DVI adapter that's passing a DVI signal carried by the DisplayPort cable to connect to a DVI monitor. What that is doing is actually *converting* the DisplayPort signal to a DVI signal. For this, it requires power - and you can see a power lead going into the little box.

Hence, Eyefinity will work with 3 DVI monitors if you have a DisplayPort -> DVI *converter* for one of the monitors.

Can anyone read the text on the adapter?

I'll try some googling.

Hence the term 'Active', means its not just a passthrough. Its converting the signal. Also keep an eye on the supported resolutions, all converters may not be the same.

I can do better than that.

Fornowagian - that looks like the same product, but the main page for it has had the image photoshopped to show accells name on it by the looks of it.

See my linky, they have eight coming in today, and another eight next week.

maxilive · 25 Sep 2009 at 14:29

But that is 1 lane, I think it needs to be Dual-lane.

Manstein · 25 Sep 2009 at 14:44

Is this a definate fix then? Will it hook up old monitors and new, and work ok?

I should have read more about eyeinfity xD

I can understand it not working above 1680*1050 cos of the limits of DVI but why cant the card run 3 x 1680 on DVI but just not go higher? that has to be software or card firmware related as TH2G managed it.

maxilive said:
EDIT: Epic find Typhoon!!!!!!!! Now to try and find out where I can get one of those bad boys!

Good spot! I have to say i was very keen on eyefinity maybe so keen my eyes just didnt see all the nonsense about DP

The DP adaptors should become way more readily available if they actually work as now there is a real good reason to manufacture/sell them. I posted in the OCUK suggestions foruma bout them a couple days ago, no response yet...

Don't know - it might be worth contacting ATI support to get confirmation or denial.

maxilive · 25 Sep 2009 at 14:57

I don't mind as my monitors only go upto 1680. I'm wondering if a DP to DVI/HDMI cable would work? Or would that have the same issue as using a non-powered DP to DVI adapter? Still struggling to find them in the UK, only Mini DP Apple ones... Maybe Mini DP to proper DP converted to DVI?

CraigN · 25 Sep 2009 at 14:59

glad i got the dell 2408s now

LeJosh · 25 Sep 2009 at 15:05

Does anybody know the maximum res eyefinity supports? I can't find it anywhere.

Also for the bezel nay sayers look out for new samsung monitors with ultra thin bezels for multi monitor setups in the future.

It says that this only supports 8 bit colour instead of 32 bit like the more expensive one.

It actually says 8 bits per component, that's per colour channel. Enough for your typical 24" display. Displayport can go to 16 bits iirc.
