I haven't seen this problem on the Atari, but I have seen it on other
systems.  (Usually the ones with a cheap monitor.) And, I recall from
somewhere in the dark past that monitors used to come with a switch
labelled "DC offset" or some such.  This allowed you to set the monitor
for automatic brightness when you used it for television work, and to
disable that feature for computer work.  Maybe your monitor is set up
the wrong way? Maybe it needs repair? I use an old old monochrome
monitor on a 520ST and it has no problem whatsoever.
