Calibration settings
Samsung C6000 has some interesting setting options in the menus.

Samsung has integrated these calibration setting options: Backlight, contrast, brightness, color, tint, and sharpness. It also has some Eco modes and in the advanced settings I found: Black tone, dynamic contrast, shadow detail, gamma, expert pattern, RGB Only Mode, Color Space, White Balance (RGB), 10p White Balance, Flesh Tone, Edge Enhancement, xvYCC and LED Motion Plus.

Gaming on C6000 is good and the much better response time also makes it more suited for console gaming than the B7000 from 2009. In the default settings it has some input lag but if you make sure to disable 100/120 Hz (or at least reduce the intensity of the system) and make sure you don't activate the film mode, input lag is fair.
