I received my Canadian Q9 version of this TV a couple days ago and it is simply stunning!
I've been tinkering with display settings this evening, and found the setting in the previous thread to be almost perfect other then the brightness. At 28, my blacks were completely crushed and everything was far too dark. After using a variety of test patterns, I found 45-48 to be the sweet spot for my panel, with 48 being what I ended with to insure none of my gradients were clipping or melding into eachother.
I may continue to play with it further; however, the results on SD, HD, and 4K are right where I want them. 45 was far too dark for Dolby Vision content, and again I found 48 to be right where I wanted it to be.
Motion rate was great 50% of the time; however, I've opted to turn it off entirely as some content (Mainly YouTube videos) came off as a little unnatural.
I should have a video of the panel on my YouTube channel in the coming weeks with a general review, with more content coming in the future with other hardware features across various inputs and sources.
At $1600ish CAD for the 65", this TV is a no brainer!
