MAG DJ530 monitor color adjustment?

Archived from groups: comp.sys.ibm.pc.hardware.video (More info?)

I have an old MAG DJ530 monitor that shows almost all pictures, whether from
a camera or the web, much darker than they actually are; usually dark brown
or blackish. When I print them they are bright and the color is excellent.

The external controls will only adjust raster shape, brightness, contrast,
etc. Where can I find a schematic that might show if, where, and how any
color adjustments can be made. And any procedures for calibration. No
success at the MAG site.

Thanks for any suggestions.
