Regarding CE Dimming in Game Mode...
I found discussion of a workaround for CE Dimming on older Samsung models (they've had this anti-feature for years). The workaround is to jack up the Brightness to keep CE Dimming from activating, and cut the white balance R/G/B-Offsets to fix the picture. The suggested settings were: Brightess:53 R/G/B-Offset:12. I tried this and it pretty much eliminate CE Dimming; even using the menu trick you can just barely see it kick in on black screens.
I found that offsets of 12 crushed blacks quite badly though. 18 works much better for me, maintaining visibiltiy of video levels (16-253). Note that this matches my previous Brightness:46 calibrated to the same greyscale pattern.
Any color calibration experts have thoughts about negative side effects to this approach? One thing I noticed is that the greyscale pattern was not pure (the greys were tinged slightly red). Since this is for videogames, where color accuracy is not a major factor, it may be acceptable.
Some other random thoughts:
- People who are bothered more by CE Dimming may have calibrated Brightness to the lowest level possible like I did, causing it to be more active.
- CE Dimming in Game Mode really sucks. It interacts very poorly with unusual lighting in The Last Of Us (bloom and eye-adjustment effects).
- Color in PC Mode is ghastly. Even on Warm2, the color is so unsaturated you can't even see the bloom sometimes. I thought it looked bland before, but after comparing a few scenes in TLOU there is no way I'd play in that mode.
