I have a Dell Latitude D820 with NVIDIA Quadro NVS 110M onboard video. This morning I went to make some desktop adjustments via the Display control panel and noticed that the system was showing two monitors. This notebook is not attached to any external monitor, dock, or projection device. There is, and always has been, the built in LCD.
I then went into Device Manager and found FOUR monitors listed there (see attached JPEG).
I "uninstalled" all of the monitors and restarted. All four came back.
I updated the video drivers (NVIDIA 22.214.171.12483) to see if there was something amiss there. Now I have new drivers, but the Display control panel still sees TWO monitors and the Device Manager sees FOUR.
The NVIDIA Control Panel only sees a SINGLE monitor (the DEFAULT MONITOR) attached to the adapter.
Do I need to manually edit the registry to clean this out?
What could be causing this?
P.S. The points go to the solution, not work-arounds! So "if it is not interfering with anything, don't worry about it" as a solution may be comforting, but don't get upset if you don't get points for that response.
