I just played with this thing for 20 minutes and tested every setting in every mode one-by-one. If I'm in Movie or even Standard mode, turning off Eco Sensor immediately stops the changes in dimming i see. if I turn on Eco Sensor, it dims
(and brightens) the picture automatically
. Samsung can call it whatever they want, and why it affects the brightness level isn't important to me, what's important is it acts like an auto-dimming feature and it's annoying. In a completely dark room it maintains a pretty constant level, but in ambient room light it keeps switching levels. Once I turn Eco Sensor off however, even in "standard" mode
- there is no longer any "auto-dimming" activity on my TV.
Maybe it's because I'm using my TV as a PC monitor hooked up via HDMI, but on my EH6030 turning off Eco Sensor 100% solved my auto-dimming woes.
