you'll get a super bright picture for bluray content much more so than the abnormally dim picture this plasma produces without the use of the AGC setting. Try raising AGC to '7' and put the black extension to '5'. These were the default settings ALREADY in custom mode to begin with, and with a gamma of 2.4 or 2.2, whatever you prefer. This has made an enormous difference and brings the picture to life. Now it's looking simular to my Sony wega CRT's brightness and previous LG plasma(Obviously better in terms of black levels performance, plus even brighter and more colorful!) and the picture looks more sculpted and has pop.
I'm sure you'll be satistyed when raising the AGC.
But if you're not using the S60 for gaming and you have the cash to spare, then why not go for the Samsung 8500 plasma? Based on CNET's review it can get almost as bright as an LED, the ABL is less aggressive and it has the upper hand in motion handeling as well! I would of went for it without question but it's unacceptable for gaming due it's high input lag, so i settled with the S60. :P The 8500 goes for quite the penny though....
For now, my Contrast is set to 90, Gamma is 2.2, AGC: 4, BE: 5 and Panel Brightness: Medium. Remember don't set the panel brightness to high if you're using AGC and BE.
Thanks, I'll try those settings, but if that doesn't do it for me, I have started to think about the Samsung 8500. But it's dang pricey isn't it!
