Quote - I think I got that from Adobe Photoshop 4 manual.

That's a good reason not to follow the advice. It may have been the best solution at the time (1998), but that is ancient!

These days we have a platform- and application-independent colour management standard (ICC).

Don't blindly fiddle about with your monitor settings. Use one or both of the links in my post above to get a rudimentary monitor calibration / profiling app. If you have Adobe Photoshop, use the Adobe Gamma control panel. They're all free. If you want to go further, you'll need a hardware solution - these start at just under $100 (search online for 'Monitor Calibration').
