 Here's a question for you guys. Is it possible for someone to fix one's 
colour monitor so that it can work with 50 HZ without buying a new colour 
monitor, and would it be advisable and cheaper to just buy a new monitor. 
Thanks.

If the vertical hold is causing you problems when you run a program that
requires 50Hz, there should be an adjustment on the back of your monitor.
One small adjustment should be fine, and you won't have to change it
when you want to go back to 60Hz.

Yes.  There are several 50Hz programs for the ST (most of the time, they are 
the only difference between euro and US versions of games).  If you get 
the demo called finalcut from atari.archive, it includes a program called 
changehz.prg.  Also, there are 50Hz booters, with which you can boot your 
computer in 50Hz (for autobooting games and demoes).  I think there is one 
on atari.archive also, if not email me.

You can only do this if you have a "recent" SC1224.  The GoldStar monitors
won't work in both modes unless you fiddle with the adjustment switches
in the back.  (Do this while the monitor is OFF.)  In fact, GoldStar monitors
evidently can't be adjusted to work in both modes no matter what you do.
People with those monitors are just scr*wed when it comes to scan-rate
dependent European software.

We have been using the GoldStar Monitors here in NZ. for many years
without any 50/60HZ problems at all, if they are set up correctly they
will work ok.

How many times do I have to post this?  I have one, and it won't work
in both modes.  Period.  Just because yours does doesn't mean
everyone's will.  I think I'm competent enough to adjust the picture so
that after several hours of fiddling on several different occasions I
could get it would work, but NO, mine simply won't do it.  And neither
will a friend's SC1224, both with the Atari label, mind you.

If I get my monitor into the state where the picture is "stable"
in both modes, the picture is shifted half way off the screen and
is incredibly grainy.  Great.

So what can I say?  NOT ALL SC1224's will work in both modes without
the adjustments being every time you want to change scan rates.

If people didn't do brain-damaged things like rely on the scan rate, we
wouldn't have this problem, but since people seem to have the attitude
of "hell, it works on my machine, it must work on everyone else's too."
we're doomed to have this problem 'til the end of time.  (Or until
everyone's running their ST's off multisync monitors.)

Mine is a Goldstar.  It took one adjustment to make it work at all Hz's, and 
the adjustment did not affect the performance in "regular" 60Hz mode.  It is 
a bit difficult to do this adjustment while the monitor is off, so I would 
recommend using the tool designed for this (a plastic TV screwdriver).
