I picked up a 55" 8550 this week, and have been trying to tweak it all week.
I'm getting about a 40-50ms audio lag with my Oppo BDP-93. I set my Denon AVR to delay the audio, so now it sounds good. If I get an Oppo BDP-103 which upscales to 4K itself, would that eliminate the audio delay? I'm guessing the TV's 4K upscaling has something to do with the delay.
The one thing I truly hate is the auto-dimming "feature". I've adjusted the settings the best I could to eliminate it without boosting the brightness too much. I looked online, and it looks like previous models turned off auto-dimming when in Movie mode, but for me, the LEDs shut off when the screen is blank, even in Movie mode. I've had to set the brightness to 50 for it to disable. I then tweaked the white balance to eliminate some of the clouding.
Is there a hidden settings menu somewhere where auto-dimming can be disabled? When I set the TV up on Tuesday, it updated the firmware to the current version. What settings do you use to eliminate the auto-dimming without adding clouding?
Is auto-dimming supposed to be disabled in Movie mode, and if so, then how come my model is not doing it? My TV thinks HDMI1 is for my cable box, but it's for everything through my AVR. Does the TV work differently with each HDMI port depending on what it thinks is plugged into it (cable vs BD player, etc.)?
