I have managed to increase the window size to a somewhat full screen mode. Here’s how I did it:
1. Right click the NV1 window (top part of window frame, not in the body).
2. Select “Properties”.
3. In the FONT tab select the “Lucida Console” font.
4. I selected font size “38”.The window will automatically adjust. The bigger the font size the larger the window gets. As mentioned above, size 38 worked for me. Just experiment with the font size until you find something you like.
5. In the LAYOUT tab I de-selected the little box “Let system position window” and centered the window on my desktop. Otherwise next time NV1 is run you may have to center the window again.
Personally speaking I found no need to adjsut the screen size to (10×18). I also found no need to use the 43/50 Line Display option (unless of course you have physically rotated your monitor to PORTRAIT mode).
This may or may not work for you but is definitely worth a try.
Hope this helps.
