Hi Sue,
I used to have a VT240 on my ST, There was always a border around the
picture rectangle, this was about 2inch across. I also thought the image
was too small, so I attempted to make it larger. I first tried the
crude way, by winding up the width and height controls on the monitor.
Some people claim they can loose the border completely doing this, but
I ran out of adjustment before I got rid of the border completely.
One of the things that makes it worse is that the normal Vt240 scan
area is restricted quite severely by intent, to keep the deflection
angles low, so as to avoid spot defocusing and convegence problems at
the edge of the screen. This means that there is already a border on
the monitor, before the ST enforces its border as well.
I next tried a super German idea, Hyperscan, this involves modifying
the video circuits inside the ST and also running a program in the
Auto folder on swich on. This increases the usable screen area by
30-40%, (out of the border area), unfortunately it only works with well
behaved GEM programs. It wont work with games for example!

If you wind up the X and Y deflection, then you will lose some
definition at the edges, but normally it is not noticable.

Yes but they are inside. Unless you are used to working on EHT
equipment, and are aware of the dangers, I would recommend that you
leave well alone. Have a look at the FS RED FICHE VR241A mini ref
service guide. The Vertical Size and Horizontal size controls are
located on the let hand side of the monitor (looking from the front).
It may be neccessary to tweak the Vlin (on the rear) after changing
size. You cannot adjust Hlin.
Cheers
Pat.
