m9700 DVI question . . .

post #1 of 14

Anyone know if the m9700 uses a dual-link DVI-D connector? It looks like it can accomodate the extra pins on a dual-link cable, but I'm wondering if it actually is (would be nice to plug into a 3007wfp with support for its full native resolution, which aparrently requires a dual-link DVI connection).

I think all of the Nvidia 7900 line have dual link DVI-D outputs, so I'm pretty sure the m9700 is dual. It lists a DVI-D connector in the tech specs on the website.

Anybody that's received one have a manual?

Yes, the Aurora m9700 has a DVI-D link port. You should be able to use one of those monitors.

Considering it doesnt work on my M1710 with a 7900 GS i doubt it will work on a m9700, atleast at the full 2560x1600 resolution, it will probably be limited to 1280x800.

According to a sales rep it's not a dual link connection. I don't know if she actually knew what I was talking about, but if we assume she did I'll be crying myself to sleep for a couple days :-(

The Dual-Link DVI question

Hello Folks

Don't get confused. DVI-D and DVI-I are types of DVI connections and designate the PIN setup and do not mean Dual-Link. Dual-Link means there are twice as many wires in the cable and this is a requirements for supporting the 30" Dell and Apple monitors at 2560 X 1600. I have the dell monitor and only can use it with my XPS 600 and not my m170 laptop.

Also another point of confusion is Dual DVI which just means two DVI connections. This also is different then Dual-Link. Do you think they could have made this any more confusing?

The only laptops that support DUAL-LINK are the new MAC lineup. I am unaware of any of the PC laptops at this point.

Dual-Link will say Dual-Link and not DVI-D.

Please let me know if there are any Dual-Link DVI windows based laptops at this point.

I hope this was helpful

Thanks

Greg Smith

Thanks Greg!

I did a little reading over at Wikipedia about all the compexities of DVI before posting, but I don't think I articulated my question clearly enough.

Thankfully you got what I was trying to ask, and answered it!

Although I'm a bit sad that it's not a dual-link connector, at least it won't come as a surprise further down the road.

I believe the Clevo d900 models with the 7900gtx are dual link dvi. Darthbeavis bought a Hypersonic based on the clevo d900 and it powers his 30" Dell monitor.

I remember reading all the 7900go line would have dual link, but if the m9700 doesn't, that must not be true...

So.. just for you I called up Alienware technical support (Hey they say 24/7, why not now) they said that the m9700's DVI-D link will support the 2560x1600 resolution of a 30" monitor and it is Dual-Link.

Oooh that's awesome news!



Although my m9700 (phase 9 - sooo excited!) ate my wallet for breakfast the other day, now I know I can feed my next one to a 3007wfp (some day I hope).

Thanks Kazkek! I suppose I should have tried tech support rather than a sales rep for that question - don't know why it didn't cross my mind before.

Can anybody confirm that this is the case for sure? I've read elsewhere that the m9700 DVI is not dual link, and so won't work with the 30" Apple Cinema Display at full resolution. My purchase of two m9700s depends on knowing this for sure (yes, I don't trust the word of an Alienware tech support person!).

I don't have an external that supports that resolution, and I'm not familiar with how to check otherwise.

I did go into the driver settings, and mine is set up for multiple monitors for some reason. The first monitor it lists is the lcd and it tops out at 1920 x 1200. The second monitor shows a slider that goes to 2560 x 1600. Not sure that means it'll support the 30" but it does show that resolution for monitor 2 does appear to offer the required resolution...

Here's Arima's spec page for the m9700 base platform. Needs to be updated...

http://www.nvidia.com/object/go_7_series_techspecs.html

According to the specifications here the NV 7xxx Go video cards can support resolutions to up to 2048x1536 at 85Hz on an external monitor. It can be connected to a 30" monitor but it will be limited to the maximum resolution that the mobile card can provide.

The Apple 30" Cinema Display's optimum resolutions are 2048 x 1280 and 2560 x 1600 pixels, but can also support 1920 x 1200, 1280 x 800 and 1024 x 640. (source)

Keep in mind that mobile video cards have certain limitations that desktop video cards don't including maximum external resolutions.

Well the only real way I know to know for sure a port is NOT dual link, is if you use a external LCD (with dual link cable i think) and load of a linux boot disc and look at the Xorg log it will tell you:

(II) NVIDIA(0): NVIDIA GPU detected as: G70
(--) NVIDIA(0): VideoBIOS: 05.70.02.19.12
(--) NVIDIA(0): Interlaced video modes are supported on this GPU
(II) NVIDIA(0): Detected PCI Express Link width: 16X
(--) NVIDIA(0): VideoRAM: 262144 kBytes
(II) NVIDIA(0): Using ConnectedMonitor string "DFP-1"
(--) NVIDIA(0): DFP-1: maximum pixel clock: 330 MHz
(--) NVIDIA(0): DFP-1: Internal Dual Link TMDS

Since it is 330Mhz and tells you it is dual-link, this should be good however this is what my XPS gen 2 with a geforce go 7800 gtx reported and it was a bios bug which actually just gave me lines with my 3007WFP, even when trying to run at 1280x800 except with specialized drivers. I even got lines in the bios as well. My M1710; however, lists:

(II) NVIDIA(0): NVIDIA GPU GeForce Go 7900 GS at PCI:1:0:0
(--) NVIDIA(0): VideoRAM: 262144 kBytes
(--) NVIDIA(0): VideoBIOS: 05.71.22.16.13
(II) NVIDIA(0): Detected PCI Express Link width: 16X
(--) NVIDIA(0): Interlaced video modes are supported on this GPU
(--) NVIDIA(0): Connected display device(s) on GeForce Go 7900 GS at
(--) NVIDIA(0): PCI:1:0:0:
(--) NVIDIA(0): Dell 3007WFP (DFP-1)
(--) NVIDIA(0): Dell 3007WFP (DFP-1): 165.0 MHz maximum pixel clock
(--) NVIDIA(0): Dell 3007WFP (DFP-1): Internal Single Link TMDS

So i get stuck at 1280x800 resolution, but atleast no lines, and bios/linux console works for me. I have yet to see a PC laptop that is dual link, so this will be news to me.
