I picked up my 65 Q80 last night from the Delivery warehouse. Took about two hours to take down my Samsung 55 JU7100 (I'm gonna miss her) and put up the Q80. After turning off the options that dim the picture based on room lighting and doing some small tweaks in Standard Mode, I am quite satisfied with the picture.
I watched Survivor with my wife and then switched over to the ACC Tournament on ESPN2. I don't have my LG OLED 65C7P right beside it to compare but man, basketball sure does look pretty on the Q80! This is all with DirecTV Satellite.
I will of course continue to look at other material and tweak some settings here and there but I am very impressed with out of the box picture.
Also, Ambient Mode has some default pictures that make the TV look like a 65 inch piece of art. Were in not for the Soundbar below it, a visitor would be hard pressed to think you have a television on the wall.
Can you test dimming in gaming mode and gaming mode in general? Thanks.
