I'm really bummed about the brightness of the X850E at min brightness. It's really too bright at night and now that this beautiful display is in the living room everyone wants to watch it and use their favourite devices (someone has a movie they want to rent on Apple TV tonight for example, which has caused a lot of confusion at why I don't want to be present. If you thought explaining flicker was bad excusing yourself from a device is 10x worse).
I think I will return it and stick to the one area where I can control all the variables, the home theatre in the basement (this area is understood by everyone to be my project).
2017 LG OLED has much better motion handling than last year (some thought that could be a trigger on these TVs? I don't remember) so I want to try them out now.
It's a shame because the X850E is fine otherwise. This is how I feel about the BenQ EW2750ZL (and even that isn't nearly as bright).
On the LG C7 100 cd/m2 is 16/100 so there might be more room for adjusting down the brightness, and the review on Rtings makes mention of an "Automatic Brightness Limitor" that reduces the brightness of very white scenes. Gonna have a peak in the store. It is out of my price range though significantly.
in the end I'm still glad and very lucky to actually have both a usable TV in the basement in my plasma and also a good display in my office in the BenQ EW2440L. I know some don't have any display they could use. Just wish those around would realize it isn't personal (and that watching TV in excess is really low effort and not that good in terms of quality time spent together).
