If you look here:

You'll see my version of a raster cabinet with a easily rotatable monitor :-).
It's a 25" monitor. If the game has been off for a good amount of time (maybe
20+ minutes), I can rotate the monitor in any direction, and the colors will be
fine.

However, if I go from playing a Horizontal game to a vertical game, as I turn
the monitor, the colors will change. By using a degausing coil, I can fix 90%
of the monitors color in about 15 seconds, but for some reason the upper right
corner (which would be the lower right corner in horizontal mode) remains
unchanged :-\. Of course, if I turn the game off and turn it on a few hours
later, the corner color is fine again.

So basically, you can rotate the monitor as frequently as you like if you use a
degaussing coil, but even if you do, you may still have some minor color
oddities on the outer edges. Minor, IHMO, but YMMV.
