Thanks for the responses.
I picked it up last night.
I have to say I was a bit caught off, if not a tad disappointed or at least confused by the image quality at first. Normally you can set these things to Calibrated Dark and tweak it a tiny bit and you have a superb image. I found this set to look a little bit washed out, almost as if there was a slight hazy filter over the whole screen. It just didn't have much POP to it. I tested a few SDR and HDR sources, including some of my "go-tos" and they were good but not great compared to my memory of my P50-C1.
So I decided to re-invent the wheel and heavily tweak the settings. I actually found that I had to bring the backlight up a bit, brightness down, contrast up, gamma up, set dimming to at least medium, etc, in order to produce an image that looked good, has detailed blacks and had some bright pop as well.
In fact, on HDR10 settings for Netflix movies, I brought the contrast all the way up towards max and brought backlight up, brightness down, etc.
Finally I got the thing to look STUNNING. I tested a range of movies and shows, from dark horror movies like The Witch, to animated shows, action movies, Star Wars, Marvel, etc. Looks superb right now.
I guess I am just a little surprised that it seemed so washed out and flat out of the box, no matter which preset I chose. Usually calibrated dark is a good starting point. Now when I switch between my custom settings and the presets, it is laughable. BUT, I am also confused why I would need to adjust them so high... I usually leave contrast and b rightness at 50 as far as I recall.
Anyway... am now VERY happy with this set.
Also, no banding, DSE, blooming, or ANYTHING yet.
Only artifact I've seen is that occassionally(?) there is a motion blur/judder, like when a TIE Fighter moves across the screen it's wings judder and it lookes like there are two ships? I hate the smoothing stuff that inserts fake frames (soap opera effect), but should I be using "reduce judder"?
The only other thing I noticed is that SDR content sometimes look really bad. Is it bad upscaling? It looks heavily compressed with lots of digital artifacts. I'm wondering if it is just a source/andwidth/compression issue and I am noticing it more with the larger screen
Cheers and enjoy your sets!
