30" monitor LP3065 with NVIDIA GeForce 8400GS 256MB SH

Hello, we are having trouble getting the max resolution working on this monitor at 2560*1600. The video card has a only single video output at the back, which is  a DVI port with 59 pins. We are using a splitter to take the 59 pin down to two dual DVI ports. One of the dual DVI ports plugs into the 30" monitor.

It works at 1280 resolution, but as soon as you take it up to the max res, the screen just blank.

Thanks,

To use the max resolution on your display, you need a display adaptor that has a dual-link DVI port. Unfortunately the 8400GS only has a single-link DVI port, so you cannot use the monitor at the max resolution. (Singe-Link is generally limited to 1600x1200 digitally). You will need to get a display adaptor that has a dual-link support, which you can tell by looking at their product specification pages.

Sounds like you have a slimline. 59 pins? On one connector? Dual DVI should have 3 rows of 8 pins and blade. If it has analogo (for a DVI to VGA adapter) then you get 4 more little pins around the blade - 29 little metal pins. Sounds like you do probably have dual-link. Here is some more information on DVI:

If you do have dual-link, you may need to update your video drivers on your PC. Try that first if haven;t done it in a while.

 

Also, you mention a splitter - that means you've got some extra cables involved and the likelihood of having a DVI-I cable being in there is pretty good. A DVI-I cable will not work and will cause the exact problem that you are having. To test, do a direct connect between the PC and the monitor using a DVI-D cable. Let us know how it goes.

I am an HP employee expressing my own opinion.
Please post rather than send me a message. It's good for the community and I might not be able to get back quickly. - Thank you.

The problem is the video card has 59 pin plug so we can't directly plug into the 30" monitor, this monitor has 3 DVI-D ports, one of these ports handles 2500*1600 right?
We have that splitter, that takes the 59 pin and split into 2 DVI-Ds, so I am under the impression thatthis video card and drive TWO 2500*1600 monitors?
Any thoughts?
Thank you
George

The 59-pin plug is used whether the card supports dual-link or not. Unfortunately, even if on the outside it looks like it supports dual-link, the hardware itself must support dual-link. On the NVIDIA website, it states the 8400GS only has single-link support. See: http://www.nvidia.com/object/geforce_8400_tech_specs.html

That is interesting, this is the info I got from the HP website

It does say:

Dual-link (DL) DVI support for high resolution LCD monitor support (such as the HP LP3065 LCD monitor)

Any thoughts?

Actually, it seems like you have the model video card in the link below, because you say you have a 59-pin connector. According to these specs, your card can only go to a maximum of 1920x1080 on one display. If the other 8400 model is compatible in your PC, perhaps you would want to acquire that card instead. http://h10010.www1.hp.com/wwpc/us/en/sm/WF06c/A10-51210-64268-348724-64268-3454917-3454918-3673477.h...

Hi,

 

The 59-pin connector is known as DMS-59, and is generaly used on 2D multi-monitor cards (NVS 290, NVS440 etc..). You need a break-out cable to connect either VDI or VGA to this connector.

 

However, your card doesn't have Dual Link DVI connector, and hence cannot support 3065. Upgrade your card to either fx570 or a compatible Geforce card with (preferably) 2 x Dual Link DVI conenctors.

 

Bests,

Thanks guys, you are right, the card we got was x1 which does not support 2500*1600 res. Bought the Radeon 3850 and got it working!
