I'm having trouble getting two monitors to work. They used to work fine. There have been no changes to hardware. Now the DVI monitor is blank. The DVI monitor does work with other computers (I'm working through a KVM switch).

The docking station is a type 2504. I have both the VGA and the DVI port hooked up to identical flat screen monitors. I have no intention of messing with that because the setup is working successfully via a KVM switch. Both ports and both monitors are working. However, there is a problem with swithching modes with the Lenovo laptop. The problem does not exist with any other computer working through the KVM switch.
Please note that:
You may note the use of past tense. I simply gave up and went to doing productive work on one monitor. After a few weeks, I went back to NVIDIA Control Panel and the second monitor was detected. I was able to Display / Set-up Multiple Displays via NVIDIA Control Panel. Subseaquently, I was able to use Windows Control Panel Display to enable and configure the second monitor and both monitors started working again (without having made any changes to wiring etc).
I don't believe there is any difference in how I used NVIDIA Control Panel on this successful attempt than in any of the earlier failed attempts. There seems to be some sort of a problem with getting the Lenovo to recognize that the second monitor is really there. Please addess this part of the problem as I expect to repeat the process in an upcoming meeting with this laptop.
Thank you for your attention.
