Displayport-compatible screens needed for Eyefinity?

Post by Mach1.9pants »


Agree. The Eyefinity6 card must be able to support 6 single link DVI connections via simple passive adaptors. If you want dual link resolutions then you sacrifice two outputs each so you end up with 3 - the same as the current 5870.

It needs to be fully DP+ capable, able to switch each to single link DVI output.

If the 6 card is effectively gimped by the requirement to use active adaptors then the whole fuss of Eyefinity is going to fail...

And, if nVidia is watching and reading and picks up on these requirements for their next card then the current slot at the top for ATI is going to be very short again...

Dave, can you please confirm the DP+ capabilities of the Eyefinity6 card - can it run each output at single link DVI resolutions via passive adaptors...?
Sorry it will NOT. only 2 DP+ outputs on ALL future 5000 series cards
You may consider the dependance on DP a "misstep", but in fact DP is the enabler to this technology being offered as a standard feature on all our boards. Remember, that these have to appeal to everyone Eyefinity is not something that we are charging extra for - the product has to stand on its own two feet as a competetive solution, but with value added features such as Eyefinity, DX11 and new levels of compute capabilities. If it wasn't for DisplayPort we wouldn't be as competetive because we'd be saddled with extra cost.

All of these boards can drive two "legacy" display outputs, the additional displays have to be DisplayPort. The Eyefinity6 Edition board will be DP+, but again only up to 2 outputs - more than two outputs will still require DP.

[quote]I don't think anyone here is asking for ATi to do a "no extra cost" value add feature. I think what most of us are saying is that there should be some variation of the card that does away with DP and uses all DP+ that we'll happily pay the premium for over having to deal with active adapter costs. Would DP+ port not cost us less than a bunch of active adapters?


Simply put, yes, as it would require an entriely new ASIC specifically for this.

With that in mind, is the architecture capable of 6 DP+ ports on the 6 mini-dp card?

No. Again, its DP that makes this capable, and the architecture behind DP.

There is a pre-established market for EyeFinity and it's not currently properly targeting it. EyeFinity should set the bar low enough to allow it to gain acceptance and the DP requirement is an impediment to that, especially if DP+ could be used for a marginal increase in cost.

You're thinking only in terms of that market. Bear in mind that all previous graphics boards can only drive 2 displays, so most users will either have one or two panels - for them, adding Eyefinity capabilities means they need to add another display or two anyway.

Since you are in Canada, where can a fellow Canadian find a cheap active adapter?, the only one i can find is by Anitec and it costs $176.

Will ATi ever sell these adapters at a cheaper price?

Thanks for any response.

I just hope the proposed single link adaptors (or even the bloody 100 buck ones) are available outside of the US soon :(

EDIT: Anybody in the US want to make a bit of cash? Offer the Dell adaptors on EBay with international shipping (and a small mark up for yourself obviously ;) ) :p

During the check out process on that Dell US site you are required to check that you will not export the ordered item out of the US. 8)

It's ridiculous.

Basically our only hope now is some vendor comes up with a cost effective single-link dvi active adapter. The dual-link active adapters should only have to be used for 30". A single-link active adapter would be just fine for the rest of us. The question is now, where do we get these things? And at what price point?

Also, this means there might have to be 2 versions of the single-link active adapter. 1 for the DP and another for the mini-dp (because I don't trust an adapter on an adapter unless ATI signs off on it).

I take it that it would not be possible to use overscan compensation with Eyefinity?

(Not that, you know, I can actually afford three rear projection TVs or anything, but I'm curious.)

I won't tell Customs if you don't!

Yeah I hoppe the discussion Dave talked about come to fruition. i can wait for the Hemlock/2GB cards though. I am hoping the Hemlock will be 5870 at full spec, cos otherwise I will have to get new mobo, CPU and cooler to get 2 CF 2GB

Can you explain why a passive adapter doesnt work, i dont understand why it needs to be powered...

Sure, ATI is using DP port not DP+:
[quote]At this point passive adapters don't work. Don't buy one for Eyefinity purposes All they do is carry on an existing DVI video stream. The secret to the sauce is allowing the DisplayPort to be a DisplayPort by coupling it to a authentic DisplayPort device. And a DisplayPort device has DisplayPort electronics that tells the DisplayPort on the video card to do it's DisplayPort thing. From all the info I've gathered....

To get into terminology - there are DP certified devices and there are DP+ Certified devices. DP+ means that you can carry other signal over the DP output, allowing for passive adapters; DP only carries DP signals. The DP output on these initial boards are DP only.

Damn... thanks, i thought it just had something to do with powering the cable so that the screens dont go blank thinking they are not connected to anything, i was already thinking of maybe modding a passive adapter but this sounds like... something else, lol.

"Active" adapter means there is transcoding conversion of the signal from one format to another. There has to be some powered circuitry in the adapter that takes DP signal and converts it into the totally different DVI (or HDMI) signal. They're both digital signals but they're formatted differently. So when you use a "passive" adapter, what is occurring is you're piping a DP signal into your display via the DVI port and it has no clue what to do with it.

This basically means, whoever comes to market first with a cheap single-link dvi active adapter is going to be able to cash in on quantity sales. This really needs a street price of around $30, but I have my doubts that can be done.

I've had confirmation from Scan that they are actively working on sourcing those Active DisplayPort->DVI adaptors for those in the UK, and those who can order from the UK.

Yeah so as far as the videocard is concerned the DP port is connected to DP device and it is, the DP device just happens to be converting the signal to DVI.

On another note:

If some one is kind of enough to ship me an active converter (at my expense of course) i will make sure no one finds out hehe, everyone outside the US is pretty much screwed with Eyefinity unless they have at least 1 DP Display, cant believe ATi didnt think about this.

Cool Scan ship to NZ, I think (if not they'll go to my in laws first- EDIT: like my pre-order copy of Win7 **AHEM**))

Yeah, I was told earlier today, but forgot about it in a fit of working. :lol: Mentioned it so you wouldn't stress too much. ;)

Haha thanks, I am not stressing that much. the x2 and/or 2GB cards don't come out for a while. So I have time to sort this out ;)

There are some new images of the x2 at Hardware Canucks which show the connectors of the x2. The centre one is a mini-DP, I think? So another adaptor required LOL

Apple make a mini-DP->DVI adaptor. It's also $100. Except that one is actually sold in the UK; the only reason I've discounted it is because for the normal 5870 is would require a mini-DP->DP adaptor, then the DP->DVI adaptor. Less = More, when it comes to adaptors. ;)

No idea, sorry. PM Ben@Scan on the forum and let him know (politely! ;)) that you're really interested in the active adaptors too. I'm sure Scan will do their best.

So is the Apple adaptor active/DP+? And I can get it NZ :)

EDIT: but maybe I don't want to ...the amount of troubles that are up on their user reviews is unbelievable! This is just the NZ site
