OC 737 FMC v3 CDU display help! "Out of range"

Hi, 737 FMC v3 display help needed. I've been using the FMC for quite sometime with PMDG aircraft with no problems. Just yesterday, I couldn't move the FMC image all the way to the right of the CDU screen. The display in the FMC would cut off the right edge from top to bottom in full screen mode. In windowed mode it worked fine.


I decided to uninstall my video driver and reinstall it. It's an Nvidia GTX970 video card and everything went smoothly, but now the FMC display says "OUT OF RANGE". The video options displays Zoom 16:9, HPOSITION 50, VPOSITION 240, and AUTO. I tried changing the values, but it's difficult and it didn't help. The display is connected via a DVI to VGA adapter.


Any ideas? Anyway of resetting the CDU display? Does anyone know the refresh rate of the CDU monitor?

Thanks,

George
