The most likely reason for this is because that generation of Quadro board did not support a high enough texture fill rate to work with Ultrascope (its why we didn't certify any of them). So what is likely happening is that the screen resolution is being reduced in an attempt to compensate. Because its not our application changing the screen size, exiting the application will not restore it.

So that graphics card is not going to work. Do you have a GeForce card laying around? If you do, you can try that in it's place. The Geforce cards while much less expensive typically had the Texture fill rate to support the application.

I hope that helps steer you in the right direction.
