I've got a Dell Latitude D830 laptop and its docking station, with Vista Enterprise running. I'd like to connect a HP LP3065 30" display externally, but can't see the higher resolutions in the settings.
The native resolution of the display is WQXGA (2560x1600), but when connected Windows only sees capability up to WXGA (1280x800). The laptop display goes even higher than that, so I think something is wrong, possibly with drivers. It's got the Nvidia drivers installed... Is there something else I can try to get this working?
Thanks, I tried the steps you outlined: updated BIOS, grabbed Nvidia drivers (from Nvidia), installed -- and no luck. It feels like the docking station is the limitation, like maybe it doesn't support dual-link DVI at all. Will test further tomorrow... – colemanm – 2010-07-26T22:13:14.120
Now it starts getting really strange. I started thinking if I'd gotten the laptop to go to the real 2560x1440 or only to something which I'd considered "good enough". So I looked at the specs. http://www.nvidia.com/object/quadro_nvs_notebook_techspecs.html says that this card shouldn't be supporting more than 160x1200 but I am definitely running a 1920x1200 on the DVI right now. /n Booting from a live Linux CD could eliminate the hardware limitation hypothesis. But booting from Linux and being unable to choose the max resolution doesn't confirm it.
