The grey display is due to a limitation of the Open GL driver for your
video, which cannot handle such a large file properly. Likewise when you
change Pixel sampling from 0 to 1 you only display every other pixel and
it works in that case, for this data file. This is pure serendipity; the
Pixel sampling feature was put in as a educational idea to show students
the effect of lower data resolutuon, but it helps your display problem.

The black bars are due to 1. effect of boundary of native data, and 2.
an artifact in our displays at the 180 degree line. We may have these
fixed in our next release IDV, perhaps sometime in June.

Have you tried the IDV remapping, and different map projections
features?
