Anyone know how to correct a SM124 monitor where pixels become closer together as the screen scans right, i.e. my mouse arrow is a line on the right character position... Thanks, Spieu!

To fix it you would have to open your monitor, and there are lots of nasties which can get you when you do. Have a TV type or dealer fix this for you. It's trivial, but you have to know where to look. ============================================ Opinions expressed above do not necessarily -- Allan Pratt, Atari Corp. reflect those of Atari Corp. or anyone else. ...ames!atari!apratt

The screen can be adjusted by the following:
Centering: High voltage yoke (rear of tube)
Focus: VR703 (a test pattern of %'s works well)
Brightness: VR301
Vertical size: VR602
Vertical linearity: VR603
Horiz. size: L702
Horiz. lin: L703 <--- (try this one first)
All adjustments should be made to yield best overall picture...

A question was raised regarding the SM124's shifting of the screen
to the right, SOMETIMES, and its being normal (centered properly) other
times probably when the system is rebooted. I also get that here on my
monitor. The problem seems that the 'picture' on the monitor is never in
the same position per bootup. Allam Pratt summed up the fix with:
"No, it's not the ST hardware. It's good old analog electronics. Your
screen's horizontal adjustment is off. To fix it you would have to open
your monitor, and there are lots of nasties which can get you when you
do. Have a TV type or dealer fix this for you. It's trivial, but you
have to know where to look."
If only this was so. Adjusting the horizontal position of the
picture is good for only THAT bootup. It will, alas, shift again during
another bootup. The only real solution is to adjust, reboot, adjust
and reboot again. Get the picture position in a good compromised
location.
I'm really picky about this because I reside at a university
where Macs rule. I run Spectre 128 and am frequently demoing the ST.
I always want my SM124 to be at top shape. There's not anything that
*I* can do about the shifting, but averaging the postion seems to help.

Allam Pratt summed up the fix with: > I, too, am having the same problem. My local dealer suggested that the horror- zontal hold was off. For me, it only happens occassionally, and a re-boot will cure it. I am sure that the problem can be fixed if I had the horror-zontal hold fixed - but that costs money and time....
