This one sounds more like a hardware problem than a software problem. Try
looking to see if there are controls for horz and vert on the back of
it. A lot of older monitors had them externally. The newer ones do it
from a superimposed control panel. If you can't find any, you could if you
are brave enough and willing to risk a 20,000 volt arc start playing around
with the controls on the back of the tube but I wouldn't recommend
it. However a mister fix it in one of these small used computer parts
stores might be able to do it for you. It really sounds like the guns are
out of alignment and not exciting the full screen area.
