After calibrating it using the le5500 settings.. http://reviews.lcdtvbuyingguide.com/...libration.html
... I turned the brightness down to 49. Also the color gamut is changed to wide bc the calibration seems to push less green on this setting. This is my movie / evening setting. The day setting used is expert 2 default with the backlight turned up to 45.
I personally don't like gray blacks no matter what so FYI this is my personal preference. If the blacks are crushed, then that's the limitation I live with for buying a LCD. :-)
