The ScreenSize preferences tool for a virtual workbench works fine on my
A3000.  Just enter the new screen dimensions into the appropriate fields
and click Save or Use.  Overscan tool works fine as well.  To change the
mode from 640x200 to some other mode, use the ScreenMode preferences tool.
All three makes the changes immediately--no reboot needed.

Yes, this is due to the deinterlacer, but since you were in 640x200 non-
interlaced mode, you shouldn't get this effect.  The effect isn't that
noticeable to me and I have my system set up for 688x458 (A3000-25 with
A1950 multiscan monitor.)  I was expecting all sorts of artifacts, but
was pleasantly surprised.  Perhaps your dealer's A3000 was out of
adjustment?
