from an L1A prompt do a >q 016 default is 0x13
13=1600x1280, 00=1152x900,12=1024x1024, 14=1440x1440.
maybe you need to change this value to do so
from L1A prompt>q 016 (CR) it will show current value just key in 00, or
12, or 13 or 14.This could be related to what type graphic (frame - buffer)
inside your 4/330 if after trying to change video screen size it still
has the same problem.

Could it be the following (which comes with every colour monitor that I
have received)?:

19" and 16" Color Monitors

This monitor has been designed to function on the systems with which it
is shipped. ....
Desktop ... [and] Deskside systems configured with the GX option
(containing a GX Frame Buffer) manufactured prior to November 1990 are
not intended to support this monitor.
