You may be able to adjust that out using 'sax' - but the fact that
the edges are curved suggests that the monitor itself may need
adjustments.  Does the monitor have some kind of an interface
for those kinds of things?  Most modern monitors do.  Maybe a 'Menu'
button on the front panel?

I would try sax first (just type 'sax' and follow the prompts to
the interactive adjustment part - then you can alter the graphics
area and position with a set of buttons.

That ought to let you get the image quite a bit larger - and keep
it centered - but if that's not enough - and especially if the
edges of the image are still curved after you've gotten the
size about right - then the monitor's own controls are the only
way forward.

The outward curving is called 'barrel distortion' - or on
some monitors, it's just a negative setting on the 'pincushion
distortion' settings.

If the monitor doesn't have controls in some kind of menu of it's
own, you might try turning it off (with the computer still generating
video of about the right size) then turning it back on again.  Some
monitors don't switch resolutions very well - and that might trick
it into getting it right.

But if all of that fails and you still have curved edges then you
have a bad monitor and there isn't much you can do about that.
