I linked to my list of blu-rays which I have access to test for this supposed posterization issue and banding in faces and extreme dithering which he is seeing, but the posts move on to reply to others without offering any actual follow-up. I was fooled as well by the subject, but when you have "im not trolling" in there, I guess it should have been a dead giveaway. My last post on this thread.
LOL man. He's actually said he's already done a cal "by setting brightness and contrast" via a disc pattern. So I'm guessing he isn't using his meter, lol, although he claims he's a 100% pro calibrator and has more AV science knowledge than us little peons. Sometimes, this thread is just too delicious to stay out of, so I take it with a grain of salt and sometimes come back for fun because at this point, I know it's a troll thread and I'm just having fun.
it is so amusing to be part of a forum community...
let me catch you all up.
What I believe the crux of the issue to be is too much light ouput. THe more light, the more noise....lowering the light output dulls the picture...
BUT....last night, I was tweaking like a mad man and I came up with something that may warrant some consideration.
I put it in cinema, and lowered contrast below 50...now I see a smoother pic with less noise...but it's dull. I know that I want gamma of 2.6, but perhaps lowering contrast really throws off the gamma curve (I'll ask in the calibration forum).
At any rate, I lowered the gamma to 2.0 and then set brightness accordingly. The resulting picture was far smoother and had good depth. It was a good improvement to the point where I will likely keep this tv. No real dull areas either...so, I'm wondering if lowering the gamma when lowering the light output might have interactive results. Perhaps the gamma curve is ruined when I lower the contrast so much....and lowering the gamma value may actually be putting gamma into a better value for that amount of light output.
One may think that dark room viewing certainly doesn't require contrast settings in the 80's or 90's...it's too darn bright. At least, that's what I'm thinking.
And I do use a light behind the tv. a 6500k light, of course.
And of course raising or lowering brightness like a fool could harm the pic quality and make dithering more noticeable. But, calibration to me is about greyscale and primary colors. Any monkey can set proper brightness with a test pattern, And experienced calibrators can likely set it very close by eye. To suggest this problem was my brightness control is insulting...at best.
I have a color analyzer...I will try to plot my gamma curve with these new settings and see what I come up with. At any rate...I'm much happier with the ballpark of these new settings.
I have been a contributing member of this forum for 10 years. And I have written posts showing others how to use a color analyzer and many other aspects of calibration. I am not a rube...I had Joe Kane's video standard laserdisc 20 years ago, for crying out loud
Just from that above he has no concept of calibration a set. No concept of how to set gamma, no concept of how his controls work. He says any monkey can properly set brightness with a test pattern, but even a monkey would have enough sense to at least read a beginner's guide to cal (Curt Palme's is pretty awesome) and figure out how these controls work hand in hand. Derp, I've been teaching people how to cal for years on the forum! Wait, does changing contrast affect gamma??? I am professional science!
Apparently he has many years of experience calibrating and yet has no idea how his settings work hand in hand...
You can't just lower brightness...it will ruin information just above black. Anyone who has even used VE to set brightness would know that. You can't just fix the picture by lowering brightness...it's a fools game.
Again, no concept of how to cal or how a cal works. He wants a 2.6 gamma but is worried about not seeing the bar in the eye adjustment pattern in VE?? Aye.... Also, no one was suggesting he lower brightness to fix the picture, but above he's talking about how lowering contrast is "fixing the picture" lol.
Oh man, ok, I gotta stop now. This thread, I should stay away, but sometimes
