d.mon won't let you do that. If you give it dimensions bigger than your display, it downsizes the grass monitor to fit. In NVIZ, you can interactively resize the window, so you can easily create an oversized one, but if any portion of the window is off the screen, the resulting image file is either all black or garbage. The same thing happens if another window covers part of the rendering window. It is also worth noting that a screensaver or monitor power-down activation during rendering produces all black image files.

I don't pretend to understand the details, but the rendered images seem to be saved by a screen dump type method rather than written directly to a file. The bottom line is: If it isn't visible on the screen, then it won't be in the file.

Eric Miller suggested using the D_cell driver for hi-res images. I haven't looked into that yet.
