That MFD can't display a Jepp plate whole.
To display a Jepp plate whole you need 1024x768 in portrait, or (at a stretch) 800x600.
One product worth a look is the Iliad by Irex. I've got one right here. The PDF reader on it is crap but there is a replacement, and it works for Jepp plates a treat. You just need to print them to PDFs........... and Jepp have ensured that there is no way to get JV3 to print a large selection of plates all in one go, into separate PDFs.
