Hello all,
lot of us are out of color from AutoDimming ( CE Dimming) feature implemented in 2012 ES series of Samsung Smart TV. On german hififorum I found interesting information, how CE dimming works...
author is Dideé : (google translate)
"The automatic dimming takes effect if the average brightness value of the current image (or scene) is smaller than a certain limit. By raising the brightness (at the very beginning of the processing chain is) will ensure that this limit is never reached. And the very end of the processing chain standing white balance makes the raised brightness then reverses. So this is a high stability a "work-around".
I tried it and I can confirm IT WORKS:
How is it in real life :
My former settings (STANDARD mode)
backlight : 11
contrast : 74
brightness : 45
sharpness:0
color:34
...
...
White balance (advanced settings)
R-G-B offset : 25-25-25
R-G-B gain : 25-25-25
Using test patterns from calibration forum, namely level blacks 0 to 4%, and two day of comparing and testing with real videos etc, I have found, switching CE Dimming off starts at brightness 50, and each +/- 1 step makes big difference.
Raised level of black (brightness) can be compensated by R-G-B offset.
below are my new settings, CE Dimming is almost switched off - not noticeable. Clouding is not visible (night test WO ambient light, black remains deep black), picture color tone seems to be OK :
backlight : 10
contrast : 90
brightness : 50
sharpness:20
color:40
White balance (advanced settings)
R-G-B offset : 15,15,14
R-G-B gain : 26,25,9
gamma:0
Try it, it should work on other models from ES6xxx series, I believe on whole ES series.
For complete settings please see post nr 21 in this thread.
