Lenovo T61 running Windows XP. NVIDIA Quadro NVS display adapter.
Yesterday, something changed in my system that caused my primary display device to now show up as Display #2 in the Display properties dialog. I don't know if it was because I docked and undocked the system, added then removed a second monitor, or I modified the display presentation mode with Lenovo's display settings.
How do you assign the display number in the Display Properties dialog?
