Yeah those settings really made a marked improvement with my set. A few other people have tried them now also and have raved about them. Just for clarification, I made those from using one of the user's before and after ISF calibration settings. A few of us were trying his calibrated settings, and while I found them ok, I knew it wasn't anywhere near close considering his pre-calibrated settings were so different than mine. That's when I had the idea of calculating the offsets of his changes instead of using his absolute values.
After I did that, my color bars were absolutely perfect and greyscale was significantly improved once I figured out that the TV wasn't putting it in the proper color matrix when I up-scaled my Avia DVD. So by turning off up-scaling and making those service menu offsets, I've been really wowed by this tv. I know it's about as close as I'm ever going to get without a true ISF calibration.
I am so happy with it, I took myself off an ISF tour that was coming by. This is close enough for me to be happy.
Also, with time, it seems my black levels have really been improving somehow. Maybe it's just my mind, but they seemed to have really stabilized. Anyhow, give it a go, worst case scenario is it doesn't work for you.
I have went back and forth on the whole tint issue. Avia says -5 for me, but I've settled on +5 to get red even more under control, despite like someone else said, on the Rutgers football game noticing a very slight green to the players faces (nothing real bad and the trade-off is worth it).
