I just got off the phone with Samsung, because I wanted to hear for myself what they have to say about micro-dimming.
First she tried to tell me about eco settings, then about how each mode has its own settings. I then told her she's avoiding the question I'm asking - is micro-dimming enabled in movie mode, and is it intended to be?
After several minutes on hold, she came back and said the specs of this tv confirm that micro-dimming is functional in movie mode, and if it wasn't the image would look washed out. I told her that that's exactly the problem - movie mode does look washed out. I then read her the email Nitra posted stating that micro-dimming is intentionally disabled in movie mode. She put me back on hold and then said she would transfer me to the executive department for further help.
I explained everything to him, and he admitted he was not technical savvy, and would transfer me to their second-level technical department to sort this out.
I then spoke to their tier-2 support, and went over everything again. I also brought up ce-dimming saying that I don't like the other modes because ce-dimming is forced on in all other modes. Everybody at Samsung seems to confuse the eco settings with ce-dimming. I went into ce-dimming with tier-2 tech at length, and she told me I could disable it. I then said no I can't, it used to be in the service menu only, now that's greyout out also, so it's not an option for us to disable it and Samsung seems to not want us to have control over that for some reason. She said it's called eco solution and it's in the menu. I then told her no it's entirely different from eco solution, and even with all eco settings off I could see the effects of the ce dimming. She then transferred me to another tech.
So now I'm on with the 4th person! This is just past the 1-hour mark now.
The 4th person confirmed that micro-dimming is disabled in movie mode. As far as ce-dimming, she basically said "oh well, use movie mode then". After I told her that was no way for a company to treat their customers, she put me on hold and then came back and said they have all my information and thanks for calling Samsung.
This is the customer service you get from Samsung.
