I have been searching the web for a while now, before actually buying this set, and after to look for settings advise or suggestions.
As people mentioned, it is estrange that there are no real hands on reviews out there other than the one at Trusted Reviews. Which gives the TV a recommended and 9/10 score. Also gives good hints on some of the settings.
Other than this one, the rest are just previews that don't go into any details from real tests, or plainly copy paste from samsung web page articles.
Unless I am missing anyone out there, but if so it is surely hard to find.
Performance wise, so far I am quite happy. Coming from a 6090H Kuro. The blacks are not quite the same with the Samsung, although they are not bad at all, and in some cases much better than I actually expected (maybe my expectations were too low at this...). In other areas like detail, definition and others, in normal lighting scenes, it is better. And the extra 15 inches show off. The downside of those extra 15 inches in my case is with SD TV channels. THe quality there is quite bad. I guess too big of a screen for SD low quality broadcasting. With HD channels it is excellent though.
Coming back to blacks, the only thing I would like to see improved is when you get an all black screen, with some white or very light text in the middle. Like when the credits at the end of a movie. You can see how the black at the screen gets lighter whenever the text starts flowing. I guess this can be fixed, or at least to some extend bringing the backlight to a lower setting like 7 or 8 that some people here are suggesting. Nothing too dramatic, but the Kuro didn't do it. And you really have to look for it. I haven't noticed this in normal viewing of dark scenes most of the times. I have to try with the backlight at a lower level as suggested and see how it helps solve this.
One ting that is good in this regard though, is when there is a change is scenes or similar and the screen goes all black for a couple of secs. In these cases it really seems the TV has gone off. I think it actually does, since the back there is... black, period.
So overall I am quite happy.
The panel also seems to improve slightly as time on it passes.
We will see.
