I have a PXI-8196 embedded controller which has stopped displaying to the monitor when the windows login screen is to be displayed. Since VNC is installed, I can access the computer and see that it is trying to use an 800x600 digital flat panel for the monitor instead of the connected monitor. The system, Windows XP Pro SP2, so far has been resistant to my attempts to instruct it to not use this driver. Has anyone seen this sort of problem before or have any ideas on a resolution?
