I'm very happy to report back that (after I got the right cable) I was able to apply your offsets with no difficulty. I went back into the SM and confirmed the settings were saved.
The key is to actually follow your instructions and not get ahead of yourself.
I'm even happier to report the significant improvement in my picture! It now seems so natural compared to the factory settings.
I know you don't accept payment for the settings you provide, but if you would PM me with your favorite charity I will make a donation to it.

and take the plunge. It's not expensive, and it's not difficult to use.

, OR) I'm sure I can hook you up with two or three (maybe more) jobs. Be forewarned though, once you get here, you won't want to leave!
