Docking station compatibility with dual DVI monitors

Does anyone know if the Advanced E-port docking station for the Latitude E6400/E6500 supports dual DVI 22" widescreen monitors being used in extended mode ?

Apologies if there is already a thread on this but I find the new forum format impossible to search.  Any tips on how to narrow down searches would be gratefully received.

Re: Docking station compatibility with dual DVI monitors

I have multiple users using dual DVI monitors and the docking station. At this time, I have only been able to get them up and running using one as a DVI monitor and the other as VGA.

Another post says to connect both to the DVI output, then manually configure the monitors to the DVI input using the monitors menu system. (Not the "Auto Detect" ), then with both monitors powered up, dock the laptop. I am trying this tomorrow.

Once the dual monitors are up and running, open the windows Display properties, select the NVIDIA tab, go to the NVIDIA console and setup your configuration as desired. Exit the console, then the Windows Display properties, and it should hold the configuration.

Re: Docking station compatibility with dual DVI monitors

hello, 

It appears that the second DVI monitor won't activate until you closed the lid of the laptop (pay attention by default the laptop will go standby if you close the lid)

So, disable the standby linked to the lid closing

activate the  first external dvi monitor from the laptop using extended desktop then close de lid of the laptop.

From the working external monitor, activate again the extended desktop onto the second external monitor !

It's working on latitude 6500 with intel grafic chipset and nvidia grafic chipset..

It's possible  that there is an easier way: plug de lattitude onto the dockstation lid closed and power de laptop with the power button on the dockstation i bet it will probably work too.

Re: Docking station compatibility with dual DVI monitors

This solution does not work for my e6420.  my e6420 does not even recognize the dual dvi external monitors on my docking station.  Anyone have a idea how to get these external monitors to work?

Re: Docking station compatibility with dual DVI monitors

The dock you have does not support duallink DVI plugs.  The best way to connect a duallink DVI monitor to your dock would be by using a DisplayPort to Duallink DVI adapter.  I have tested these and they work.

Re: Docking station compatibility with dual DVI monitors

I am using the dock model PR02x, it does have to dual dvi and dual DP ports on the dock.  I have tried to using both the dvi ports and the DP ports.  Neither are successful.

Re: Docking station compatibility with dual DVI monitors

I have tried to connect my M4600 with two U3011 (*) via the DVI connections on the E Port Plus replicator via two (BizLink) active DisplayPort to dual link DVI adapters. The U3011 reaches it native resolution of 2560 x 1600 but it only results in distorted image on one screen and flickering on the other. In the latter case the screen just blanks for 3 to 4 seconds every 30 seconds or so.

It's about time Dell introduces two dual link DVI plugs on the E Port Plus replicator. Alternatively Dell should consider two DisplayPort inputs on the monitors.

(*) The DisplayPort input on these screens are taken up by another Precision laptop also docked in an E Port Plus replicator, without any problems.

Re: Docking station compatibility with dual DVI monitors

Get the laptop booted up then go right click on the Desktop, Choose Nvidia Display settings. Once in the NVidia control panel you will find a couple of areas that by default Automatically chooses which video card to use. You will probably see two "Intel" and "NVidia Card #". Select the "NVIdia" video card so the laptop will always use that video card instead of the Intel video chip.

When booting up from docking station you will not see post screen. If you ever need to get into the Bios or Boot screen just boot the laptop off the docking station.
