1) As for the image settings for Apple Tv and PS4. For both, I set the PC mode, set the backlight to 85, the contrast to 90, the color temperature to normal. The rest of the controls in this mode are not available, as I understand it, the set-top boxes themselves are already responsible for the image.
2) One more thing, everything needs to be set up when the content mode switches to hdr10 mode, here the dual setting is obtained in normal and HDR, at least for me. And I can also play with me +4, well, who can and +2 -3 enough, adds dark.
3) After flashing it is MANDATORY to reset to factory settings, password for reset is 0423
4) Disable dynamic backlight: in the service menu (enter 1950 on the Contrast item>Param Setting>DBC>DBC Enable - off. After setting "off" turn off the TV and when turned on, the dynamic backlight will not work.
