What sort of lighting environment is this in, is it a dark media-room or a typical well light by sunlight living room? Also, did this replace your Plasma or is that still serving duty in a different room?
As you know I've always been the resident AV IQ freak so I put it through its paces.
My living room gets VERY bright during the day unless I close all the blinds and pretend I'm Dracula for the day. The TV is clearly more than bright enough and by comparison, my old plasma was pretty much unwatchable with all the ambient light.
On the other hand, now it's pitch black and that was my main worry, as the black levels on the plasma were pretty good. The ZD9 has by far better blacks. Black is actually black, even in a completely dark room. And the picture can have perfect black and at the same time stupidly bright highlights thanks to the full array backlight. AND!! No black crush nor near-black noise, which is still a problem on all OLEDs.
I kept hearing about ghosting and yes, if you look at the TV at an angle and there is a bright white object against a black background, you definitely see ghosting depending on how bright the TV is (on HDR for example). However from straight on or not too much at an angle, zero ghosting and blacks are black.
Everything else, just gorgeous. The set even corrects banding as much as it can, which makes everything looks so clear and smooth (yes I'm looking at you, Destiny).
So yeah if you have the cash, for now this is a better TV than an OLED simply because of the guaranteed brightness, as with on OLED always depends on how much of the screen is bright, and the crazy contrast. Plus the picture presets are pretty much perfect out of the box.
I honestly can't speak highly enough about this, and I was coming from my revered Panny plasma, which I gave to a friend.
