I decided this morning to copy a post I made last night on the "F8500 Recommended Settings Thread
" so that more owners will hopefully get a chance to read this. I woke up this morning, turned on my tv, and have no urge to want to max my cell light setting like I normally had it...it's too bright...lol
ECO, ECO, ECO, ECO.....OMG.....Well folks, I just made a huge discovery with my 51" 8500. I'm a little embarrased to even mention this, since I have owned my tv for about 2 months now. I have never calibrated a tv, and have never measured light output from any screen before. All this recent talk about the ECO setting/bug had me wondering why I seemed to need/crave more brightness on my picture....I kept hearing owners say that with a picture putting out 45 fL (i.e. Pie's cal) during night viewing, it can be a little bright....I was still cranking the cell light up higher with his cal.....it wasn't bright enough for me........In addition, I have seen many owners calibrating movie mode to an even lower 40 fL (seems to be a standard), and all this time I kept saying to myself, that's just crazy!! I could never watch my tv with an even lower light output. I do remember messing with my eco setting a while back, possibly during the time Floridaman posted an anomaly with that setting. I remember turning on the eco sensor, then setting min. cell light to 20, then turning off eco sensor. I thought everything was fine after that.....Well, that just wasn't the case. Tonight, after talking about the eco sensor in this thread, I decided to enter into that menu, and play with the setting. I turn on the eco sensor, then I reduced the min. Cell light from 20 to around 14....i saw no incremental reduction of screen brightness by lowering the setting down to 14 or so. Then I proceeded to turn off the eco sensor, and BAM!!! My screen immediately increased a measurable difference in brightness. I couldn't believe it! I then turned eco back on, increased the min. Cell light back to 20, then turned eco sensor back off, and saw no change to the previous brightness I just gained. It's so surreal! I don't have to crank my cell light to 20 now for night viewing...it's way too bright for my eyes....we'll see what happens during daytime viewing. What a revelation!!! All this time.....Argghhhh! Pie, your cal looks fine now on my screen...no off-tinting/subdued look like I was seeing before. I can see now what you're seeing!! I'm not sure how much brightness I gained, but I can tell you that with my current cell light at 16, it looks every bit as bright (if not brighter) than I was getting with cell 20 before the eco adjustment.
