If you have the horizontal width switch set for a wide display, you
might try changing it.  I have never seen a high quality monitor
that could be set up to overscan while maintaining acceptable
convergence and pincusion distortion.  The only display standards
which normally are overscanned are those derived from NTSC like
IBM CGA or the normal Amiga display.

Amiga users with high scan rate output are asking for trouble when
they try to find monitors that bleed off the edge of the tube.
In trying to cater to this desire in the A1950, Commodore is making,
in my opinion, the wrong design trade-off.  These monitors are just
not capable of working well with the large scan angle that overscanned
display requires.
