Here's a weird 4000/AGA question: I just re-installed a VGA monitor on my A4000, and I now seem to be limited to a 672×480 viewable display in the Workbench. I thought I was able to go to at least 724×480 when I used this monitor before……. All I did was use a 1084 monitor, and run in NTSC mode for a few weeks. I've tried editing Overscan prefs, and even went so far as to delete some of the appropriate prefs files from ENVARC:sys. Nothing seems to get rid of the one inch border on the left of my screen, nor allows me to have a viewable display of greater than 672 pixels… Any suggestions? Thanks, Erik Flom
