I know you folks want all sorts of technical details and pics, but I'm more of a "how does the picture really look" than a technical person. I'm certainly interested is some of the technical details that might affect the picture quality, even if not obvious with a regular image, but ultimately, it's the picture that counts.
The 65 Z9D picture quality is simply incredible. I spend hours watching it last night and this morning. What impressed me most was the depth and clarity of the image. The blacks were truly impressive as was the brightness of the image without any blooming or blown highlights that I could see. Colors were incredibly rich and pure looking. The animated Blu-ray movies I checked never looked better.
I understand that these terms can be nebulous and very subjective. I've heard many people describe a 3D quality to an image. I've never been able to see that, until now. The picture just seems to be more "alive" and "vibrant" than any previous display I've seen. I'm wondering is this appearance is due to the greater local contrast from the master back light drive.
As good as my Sony 950B is (was), the 65Z9D is better. Earlier this year, to get HDR, I purchased the Sony 65" 930D. I knew I was trading FALD on the 950B for Sony's new Slim Backlight Drive. I had hoped it would be good enough. In the store, the 930D looked OK, but didn't cause me to swoon. Sadly, within an hour of setting it up at home, I knew I had made a mistake. The picture was good, but not nearly good enough when compared to my 950B. It lacked a vibrancy and clarity I had come to expect with my 950B. It was returned.
Enter the Z9D. In the store, even with terrible ambient lighting, I sensed a special quality to the image that really excited me. Throughout the evening of viewing many different sources, I was continually saying "wow" to myself. I know this is very subjective, and maybe I'm full of it, but this is one gorgeous display, even better than I expected. I saw absolutely no imperfections. Even if, when you folks do more sophisticated testing that I can do, you find a slight negative, I don't believe it would change my opinion of the image quality.
I'll be interested in hearing what other owners say about this display. I think it's the best set that Sony has every produced.
