This is going to sound very off the wall and weird (or maybe it won't, who knows). It's also difficult to explain, so excuse me in advance if this is a bit jumbled.
My calibrator sucked and was a piss poor expense on my behalf. The only thing he really worked on was the gray scale (white balance). He actually changed SOMETHING in the service menu (I couldn't follow his movements in the Service Menu at the time) to change the default gamma from 0 to -1 because that is what I had it set to in the user menu at the time.
When I first got my set back in May the black levels were fantastic to my eyes. On movies with the black bars, they were dark enough that they didn't "stand out" when viewing the actual movie. They didn't blend with the bezel of course, but were dark enough to not be completely noticeable.
Added a little lighting behind the television (NOT D65 certified BIAS, but it was cheap and did the trick for now until I invest) and the blacks blended in to the bezel to my eyes. Perfectly happy and thoroughly impressed with the results.
I'm now sitting at around 1500 hours on my set and noticed over the past few months the blacks on the all black portions of the screen were sticking out to me and I'd constantly be looking to them thinking "have my blacks always been this poor?"
I knew something was wrong when I turned on the same lighting behind my television and it did nothing to improve the situation. I also noticed that the set was doing a piss poor job on the DVE bluray with the basic brightness setting test. I believe the explanation is it was coming out of the black too quickly? I'm not terribly familiar with the terms.
Anyways, fast forward to yesterday and today, and I went into the Service Menu and adjusted the value in the W/D Movie from M1 to 0.93. Here's the kicker: My black levels are back to what I originally described them as.
I've had.....other little glitches with this Samsung previously. Ones that can't be explained. Besides the Cinema Smooth bug, I can't use the Night and Day CAL modes because they definitely make the picture lighter for no reason when switching sources. Unadjustably lighter.
Lastly, to mention, when I am referencing black levels, I'm saying that you could have the brightness at "0" on a black test slide. Meaning, the lowest blacks showing possible on the set with no way to lower them further. There is a noticeable difference between what I was able to achieve prior to me adjusting the gamma and afterwards.
I'm sorry for the long read, but this is a frustrating experience for me and hard to put into words. I mean, I can't use a warranty for this, they'd look at me like I'm insane. I KNOW something is off, but there is no way to prove it.
