That's ok for an normal SM124. Mine (build in 1985) does the same. Some
of the newer SM124 (with the Atari logo painted on the front) should be
able to show up to 704x480, but they're rare.

Did you have the old overscan (hyperscreen) with that manual switch or
the new "Autoswitch-Overscan" (AS-OS) which automatically change the
solution? There is a nice solution-table in the well written AS-OS dox. 
800x600 isn't mentioned there. The maximum for monochrome monitors 
should be 752x480 on NEC Multisync GS or a good TVM MG11. Maybe some
816x280 on color monitors (mid solution) but I don't think many use that.

>Does anyone know what adjustments have to be made to the monitor to do this?

You can move the picture or make it a little bit brighter but if you have
left the SM124 in original state, you couldn't get more solutions by
internal adjustments. I've tried it. 8-) And beware, that things inside could 
kill you.

Never heard of that here in Germany. There's a card for Megas called
"Megascreen" which make a little bit more in monochrome than AS-OS. But
you need a Mega (don't have one) and a mulitsync (also missed) to use
it. AS-OS works with every ST (except STE and TT), every monitor and
have the better software, i think.
