Dual Link DVI-D on a AGP!

First of all a small explanation of what Dual DVI is:

"The Digital formats are available in DVI-D Single-Link and Dual-Link as well as DVI-I Single-Link and Dual-Link format connectors. These DVI cables send information using a digital information format called TMDS (transition minimized differential signaling). Single link cables use one TMDS 165Mhz transmitter, while dual links use two. The dual link DVI pins effectively double the power of transmission and provide an increase of speed and signal quality; i.e. a DVI single link 60-Hz LCD can display a resolution of 1920 x 1080, while a DVI dual link can display a resolution of 2048 x 1536"

and now...
Hello guys!
I'm on a trouble! I just got 30'' Dell screen but i can't use it atm, my problem is that the screen needs dual DVI-D card, and my X850XT doesn't has it.
I was thinking if i could find any AGP card with the dual DVI-D (notice that dual DVI doesn't mean 2x DVI outputs...)

If i can't find one i will have to move to a new computer with PCI-e and so on...

PD: I thought i should be able to actually use my card with this screen but at less resolution, i didnt had much time to test the thing. The monitor starts, shows the boot up screen, windows loading screen but when login message appears it keeps blank

Gainward do a lot of Dual DVI as std, I my 6600GT had 2 x DVI of which 1 was Dual DVI I think.

Dual DVI on AGP is not unknown or that much of a problem have a hunt arouind 6xxx and 7xxx probably have it. Not sure about ATI.

That's a terrible explanation. Where'd you get that?

No it doesn't it just needs a SINGLE DUAL-LINK DVI output, which you will not find as DVI-D, but as DVI-I (which includes the Digital portion as well).

Actually it does, dual DVI meands 2 DVI ports, DUAL-LINK DVI means two tmds on one DVI port, which is what you're looking for.

Oh no! You can afford a Dell 30" but the prospect of getting a good PCIe rig and card to power it seems out of place? :|

Why would you think you can use it when D3LL specifically says no?
As for the display of the load screen that support is built into the monitor to ensure the ability to show the BIOS screen which most early WS panels didn't do, and LCDs only support certain resolutions, but outside of that 640x480 you're stuck.

The nice thing is that most of the new VPUs for AGP have built in support for at least one Dual-Link DVI out. The X1300, GF7300GT (don't think the GS has built in dual-link) X1600, GF7600, X1650 series cards and the upcoming X1950Pro AGP. All have at least 1 dual link DVI, and some have 2 (especially the X1950P which has 2 dual link TMDS integrated into the VPU). Outside of those general card you need to look for specialised cards like the FIreGL and Quadro, or the others made for the Apple Displays, like the R9650Pro, R9600 PC&Mac version and the 6800GT DLL.

Note: the only GF7800GS is the Gainward GF7800GS+ Bliss because the BLISS is not a GF7800 without the integrated dual TMDS, but a GF7900 which has an internal integrated Dual link TMDS just like the others above.

So in my opinion if you want to do any gaming, then you need at least the GF7600GT, X1650Pro or preferably the X1950Pro.

But I would say you should consider looking into upgrading to PCIe especially for gaming. At least the X1950P might do that monitor justice, but IMO that thing need an X1950XTX or GF7900GTX or even better something G80-esque.

I highly doubt it was dual link.

ATi has more dual link DVI cards in AGP than nV, and pretty much always has thanks to their tight association with Apple.

I'd say forget anything GF6 series, they are rare as dual-link cards, and overpriced and comparitively underpowered. The current options I listed above are far better regardless of which vendor.

Thanks for your input TheGreatGrapeApe.
You are right, i was in a hurry (go to work) and wrote the whole thing in a rush xD. Money is not a problem but i dont need a computer upgrade just to have a PCIe for this screen :p :p 

I was thinking in get that X1950PRO AGP (both DVI are Dual Link i just checked!) and then upgrade the computer next year.
I play Battlefield 2142 and World of warcraft, and my computer runs great with those games :p 

Sometimes i think its not a good idea to buy AGP card now when im planing changing everything in a couple of months, but i think i could wait a bit more, maybe April :lol: 

Oh and i got that explanation from here
http://www.datapro.net/techinfo/dvi_info.html

Any idea what the price range wil be? (x1950Pro AGP hehe)

I'm pretty certain it was duallink (thanks for the terminology corrections.) but regardless it would not have been particulary useful for high res gaming.

My other point was more to iterrate that they are not particularly rare overall, and to indicate that ATi is worth looking at as I have no information about ATi, not saying they don't, not saying they do.

oh 13th i forgot about you, thanks for the info aswell, but i think i might get a high end AGP if i want to keep my current PC for a couple months before i move to Quad (maybe :p )

Nothing yet but I suspect $250 based on the usualy PCIe price + premium of ~$50. Of course the day it launches it'll likely be $300 on some price gouging e-tailers, just like the X1950P PCIe was overpriced for the first little while.

I'm interested in getting a dual link DVI D card also as I too want to buy the Dell 30", my Asus P4C800-E deluxe motherboard has just an AGP slot. I'm after looking at the specs of some of the AGP cards that theGreatApe has mentioned and so far each one seems to be PCI Express according to the ATI and NVidia sites. So I'm a bit confused. Is there an AGP card that supports dual link dvi D? Also will I be able to connect a second monitor as i do with my current ati radeon 9600 card.

I understand the argument to upgrade the motherboard also, for me personally though it's not that necessary, I'm not a gamer just a fairly serious online poker player and that's about the only reason why i want the very high resolution.
October 16, 2007 5:30:02 PM

I can't edit my post, perhaps because I'm a newbie :??: 

Anyway after doing some more searching I have found the AGP versiosn of the cards theGreatApe mentioned :)  .

Will these work on my getting(if not already) dated Asus P4c800-E deluxe motherboard?

Thanks for the info ragemonkey, though the reviews the card got from bestbuy are kinda offputting.

what's with all the primate aliases here btw :kaola:

Well the primates are the more intelligent forum animals, eh! :wink:

For compatability you really need to check with the mfr and with places like the ASUS forums. AGP compatability can be tricky since some are very finicky, the P4C800 is a solid MoBo, but this is not an upgrade that was in it's intended future. The rumblings I've heard are that the Catalyst 7.10 version still have issues with some of the newer AGP cards. And really you'll want the latest drivers if you're gaming with these. For basic day-2-day work you shoudl be fine.

The thing is what do you want to do with the card?

Since my original post things have changed somewhat and there are alot of different options for both ends of the spectrum.

The HD2400 and 2600 are GREAT cards...... for 2D and very VERY light 3D work.

For any kind of gaming on that 30" panel I would suggest you go with at least an X1950Pro and preferably the much rarer AGP X1950XT.

The HD2600 though would be my recommendation (over even the X1950XT) if you are focusing mainly on 2D and light 3D, the benefits outweigh the negatives.

But like I said, check the compatability with your mobo, all these newer AGP cards can be a little flakey, just like the R9700-9800/FX5800-5900 were with early 4/8X MoBos.

I'm not a gamer, all I really want it for is for the large resolution for playing poker.

Then the HD2400 should be more than enough, and not pose too many problems for you being a non-gamer.

Firstly thanks all for your help. Just to let people know. I purchased an MSI NX7300GT TD256 graphics card, it was the only one I could find in local pc stores. I live in central Portugal so not a huge selection on offer. Had to travel about 50KM to even get that one. Anyway the card works for me and supports the 2560x1600 resolution of the DEll 3007WFP which arrived this Thursday. Maybe this card isn't good enough for serious gamers but for someone like me who basically just wants an AGP card to support high resolutions it worked, at least on my Asus P4c800-E deluxe. :D 
November 19, 2007 11:28:31 AM

I like my new Dell 3007WFP so much that I'm seriously thinking of purchasing a 2nd one, this would mean of course I would need to get yet another graphics card, one that has two dual link dvi-d ports. Have a feeling this might be too big an ask for an AGP card, but asking just in case?

I've had the Visiontek HD2400 with DVI 2X using ATI drivers for 6 months; also the NVVidia AGP; the Visiontek worked much better; don't use it for gaming and it's allowed me to run two Dell LCD monitors just fine (22 wide) and 1905.
