Found this: http://www.ks.uiuc.edu/Research/vmd/mailing_list/vmd-l/26535.html

In which John mentions:

" In addition to Josh's suggestion, within any running VMD session
(whether text mode or otherwise) you can always use "display resize XXXX YYYY"
to set the image size that renderers will use by default. The only case
where this is not straightforward is actually when you do have an interactive
session running with OpenGL, as some window managers will prevent the window
size from being larger than the screen unless you push part of the window
outside of the screen boundaries prior to running the display resize
command... "

So, that is what I was seeing, the windows manager was stopping vmd
from making the display window larger than the available screen size.
So off to google ...

Discovered that can set the window size another way:

Top Bar of Window >- Right Mouse Click -> More Actions -> Special
Window Settings -> Size and Position -> Size - specify dimensions of
window and select apply now

To get the correct window size needed to add 8 to the x direction and
29 to the y. Most likely to do with the borders of the window.

So now I can get it to render at higher resolutions, above and beyond
the screen size. Problem solved.
Catch ya,
