Graphics resolution on Z240

Z240
Microsoft Windows 7 (64-bit)

I am trying to setup my new HP Z240 workstation, but cannot get the graphics card to operate at any resolution above 1024 X 768. The graphics card is an NVIDIA QUADRO K620. It is connected to the monitor with a DVI-D Dual link cable. The monitor is an HP w2408. The monitor has two inputs (DVI and VGA). I have the VGA input connected to another HP computer with a NVIDIA GeForce GT 610 card (this computer/card/monitor displays at 1920 x1200). When I checked the adapter modes (using the list modes option), the best mode listed is 1024 x 768. The NVIDIA spec sheet lists the max resolution with DVI-I as 2560 x 1600 or 1920 x 1200. What can I do to get the max resolution from my monitor (1920 x 1200)?

Update.  Problem solved. When I realized that the monitor in DVI mode was not being recognized as PNP, it pointed to the monitor as the problem. Installed new monitor, everythng works as it should. Evidently the VGA input to the old monitor functioned properly while the DVI portion was defective (card or cable connection).
