Ok, so step 1 and 2 are ok...brightness and contrast.
The color part I simply cannot get proper...I can get blue and red ok, but green, forget it.
As I have an analog CRT (rear projection) I just turned sharpness off.
I watched a few movies and they simply have an "odd" feel to them...much less bright than before (which I understand is a good thing), but the colors "feel" strange, or PERHAPS they're more realistic.
I just have no way of knowing if what I did made things better or worse.
