For me and my 467 (with v302 firmware) I have found that the most important tweak was setting gamma from 4 to 0. To my eyes, the gamma 4 setting made the picture too contrasty. That is, dark to mid hues seemed crushed towards dark, while mid to bright hues seemed crushed towards bright. This probably makes the picture stand out on the showroom floor, but does not look natural to me. Shadow detail also improved at gamma 0.
Also, setting gamma to 0 (I did it for DVI, comp, and ant) seemed to eliminate the "sunburn" I used to see at gamma 4.
I've tried one other poster's RGB settings (for hln507, v302), but for DVI I returned to the default settings and think it looks best. For Ant the tweaked settings looked better.
Obviously none of this was done scientifically. I just went by what looked best to my eyes. I'm still tweaking comp3 input, skin tones look slightly green.
If you want to venture into SM I would try gamma 0 or 2 first. If you still have problems with neon grass, changing the RGB gains/cuts is probably your next step.
As always, record your defaults first.

Fellows, after reading many threads on the HLN617W, I still can't come to a conclusion about how to turn a football or baseball field from neon green to natural grass color. I'm a bit tentative about going into the service menu, but I'll do it if there is a difinitive fix. I'm connecting with analog cable straight to the DLP. The OOTB picture was excellent with this exception. The analog cable is surprisingly good. Also, under the above scenario, will turning gamma to 0 have any positive effect? If so, what?
