Default FSX VC and gauges

Has anyone been successful in correcting any of the default FSX gauge problems? One in particular that is very annoying is the MFD in the 777 vc. I shows up as a black screen and without the knobs. I've searched the forum and come up empty. I did find where this general question was asked on about page 90 or so but there was no response.Might this have something to do with the pixel size of the gauge not being properly sized for the mapped area it is to occupy in the vc? If so, would resizing it a few pixels at a time be the approach to correcting the problem.I don't understand why a gauge will display perfectly fine in the 2D cockpit and doesn't display at all in the VC.Some help with this would be appreciated.Thanks.
