What is CE? Contrast Enhancer? Color Enhancer?
What is the difference between CE-dimming and Microdimming? How can I test the difference; what what kind of scenes?
I understand Microdimming is not active in Movie mode. Is CE-dimming active in movie mode?
Don't worry about it - a lot are. It confuses me too to a point because of the lack of information and the fact that Micro Dimming seems tied to CE Dimming - yet Samsung doesn't admit that, so who knows.
Samsung says Micro Dimming "scans zones across the image and adjusts brightness to deliver deeper dark tones and brighter whites. It also eliminates the "halo" effect and image distortion that can happen with diffused lights. The Ultimate version of this technology optimizes the quality to new heights by scanning 2x the number of zones in the image. The result is a crystal-clear picture with realistic, vivid detail and accurate color reproduction." It darkens and lightens individual sections (zones) of the screen so that blacks look better and brighter areas stay bright. Think of a movie in widescreen. On a very simple level, the film would stay bright and the black bars would be very black. In Standard mode, you'll not less flashlighting in the corners because of Micro Dimming.
What is talked about as CE Dimming, makes sure the whole screen stay bright during bright scenes, yet darkens the whole screen during dark scenes (not in zones). This adds to making blacks better with less clouding and flashlighting too but for some of us, the negative effect drives us crazy. In Standard mode, if you want the opening scene to Star Wars, as the "crawl" goes away, you see just a star field, which you notice starts to go very dim, then the camera pans down to a planet. As the planet comes into view, you'll notice the stars get bright again. That is CE Dimming.
As for the issue you mentioned where the whole screen goes black, I don't know what it's called, but the TV is literally shutting the screen off momentarily. There seems to be a threshold of black that initiates it. Normally this will occur with your Brightness on 45 or lower. If you bump Brightness up to 46, it won't happen. Then if you turn Dynamic Contrast on Low and/or Black Tone on Dark, this "feature" will kick on again, shutting your screen off during black transitions, because that black threshold was achieved again, so you'll need to bump Brightness up to 47 to counteract it. Now if you say bump Black Tone even darker, you may once again need to bump Brightness to 48, if you don't want your screen to shut off.
