Hi all,
Glad I found this thread - I had been looking through the 550 thread for comments on this model.
I posted this on cnet hoping to help somebody out with calibration:
I have some basic picture settings, but I am not an ISF calibrator. I had a Sammy PN58B550, but it was destroyed and I replaced it with the PN60E530. I used the AVS709 calibration disc (AVCHD) played through a Panasonic DMP-220 blue-ray player to calibrate, along with the mp4 version of the same disc, a PC grayscale JPG, and ICAL TV calibration game played through an Xbox 360. I did not use a blue filter to test for saturation and hue, nor did I use a meter or calibration software to measure the results. I use these settings because I feel it gives me a great balance of white and black level detail, with reasonable color saturation and tint. In my opinion, the only way to get a better picture would be to hire a professional to calibrate.
That said, and keeping in mind that I watch TV in a very dim to completely dark room, here are the settings I use:
Cell light:20
Contrast:89
Brightness:44
Sharpness:0
Color:50
Tint: G50/R50
Black Tone: off
Dynamic Contrast: off
Gamma: 0
ColorSpace: auto
White Balance: 28, 26, 25, 25, 26, 26
Flesh tone: 0
Color tone: Warm 2
Size: screen fit
Digital Noise Reduction: 0ff
HDMI Black Level: see below
Film Mode: Off
HDMI black level will only allow for the toggle if you use the HDMI-DVI connection, and it receives an RGB signal from the Xbox or other gaming device connected. I have my set calibrated to display 16-235 when HDMI black level is set to low (use for watching movies), and 0-255 when set to normal (use for playing games). If you have an Xbox, set the reference level to standard.
