My set seems to have 'settled' and I'm not getting the flashlighting that I was yesterday irrespective of backlight setting. I still need more viewing time to be sure this is the case. In any event, I love the monolithic look. When the image is bright, glare is minimal. Viewing angle seems wide to me. 3D is sharp and crisp as mentioned. I'm currently watching broadcast tv under the general scene custom pre-set and it looks great. Of course I'm certainly open to further calibration. Does anyone know what the eco power settings (off, high, low) do? I can't find a detailed explanation. Thanks.
