Some members have asked if the Eco Sensor is off, but except for one or two, most people don't say.
So, my question for this symptoms are:
1. Is the Eco Sensor off?
2. Is the Dynamic Contrast off (if your mode is on Standard)?
This are the only two options that will automatically change the contrast and brightness is the TV, and, they are ON by default (by law).
(Even tough i have read this forum for a while, i never post (mostly i do research)) Thanks in advanced !!!
I think various D- and C-series owners are posting here, so let's be sure to include model # and also screen size.
On my 59D7000, all eco / motion lighting / dyn contrast settings are disabled. I'm using the MOVIE preset (I posted my settings a few pages back). I can *only* notice the effect if I focus close-up on letterbox bars and not at all on full-screen material. PQ is still fantastic. I've also enabled GAME mode to disable extraneous video processing and there is no change in behavior. Brightness / cell light / film mode also do not modulate the effect.
The response is a direct and instantaneous function of the APL of the frame (no time delay). Based on anecdotal reports, the fluctuations on the D5x0 series are more apparent than on the step-up models. I'm curious if the effect is more or less pronounced on the 51" panel, as the MLL "floor" is likely raised to begin with.
