Why do some of my blacks look blue? - Blu-ray Forum

pokefan · 07-15-2009, 05:53 PM

At times some of the blacks on my display turn blue. It's not all the time and isn't even consistent through out the same movie. Last night I was watching Australia and the scene where Lady Ashley and Drover start to kiss behind the tree, the black area between them as they meet turned blue. But blacks throughout the rest of the movie seem fine. I've seen it in other movies as well but can't remember off the top of my head when. I'm pretty sure I've seen it in parts of TDK as well. But yet I can throw in a calibration disk and the blackest blacks on there look fine.

Is this a encoding issue? Maybe a transfer? I just don't understand why it does it at times but it's not consistent with other black levels?

Dial down the blue gain in the white balance.

Is your Sony a LCD TV? When I first bought my LCD I had blue-colored blobs in some dark scenes, often times right on a character's face (Saw IV, for example). Forum members here described the problem as ghosting, I believe, and I was able to minimize it to the point where it was no longer distracting with my TV picture settings (I don't remember which setting, specifically). I saw a lot of this in The Orphanage, even after tweaking my seetings.

pokefan · 07-15-2009, 06:09 PM

It's a Sanyo LCD. I had written it off at first as being due to having a lesser display but after it being so random and some black levels that seem to be the same displaying different I think it may be something different.

I'll mess with the gain a bit tonight and see if I can get any results.

I appreciate the help and any other tips or insight you guys have is MUCH appreciated.

their picture quality must have taken you by storm if you didnt bother considering models from samsung, sony, panasonic, or lg.

pokefan · 07-16-2009, 01:16 PM

That doesn't seem to help my issue much! Yes I know Sanyo isn't the best quality. It was a matter of needing a new tv, this is my first HDTV and didn't really know at the time what I was looking for. When the sale came up for a brand new 42" 1080p for $500 I jumped on it. Honestly though for what I spent I've been pretty impressed with it. Sanyo also has some of the highest reliability ratings on their lcd's as well.

As far as adjusting the white balance goes, if I turn down the blue it throws my colors off. Do I just combat that by adjusting the color settings? I'm a little confused as to how to adjust both white balance and color. I've just left the WB alone up to this point

what kind of "enhancements" are turned on? it could be a dynamic contrast issue.

Don't be a jerk dude. Is everyone on this site required to have a $3000 display in order to flash their coolness?

I would tell the OP to get a pro calibration, but i don't know if you'd want to spend the $250-300 it takes to get a good one.

pokefan · 07-16-2009, 04:20 PM

I've turned off all enhancement modes and gone through avia calibration as well.

I do want to get it professionally calibrated that's just not an option at this point. I'll get it done one day though.

Riff Magnum · 07-16-2009, 05:10 PM

What are you using to play bluray's?

Wasnt trying to imply that. My comment really was saying I guess he didnt do anykind of BRAND research and saw that sale price and pounced on it just because of the dollar amount. Anybody thats ON THIS FORUM, knows you dont need a $3000 display to get jaw dropping picture quality. My point was that there is SO MUCH INFO on this site (even if you are budgetary minded) to find out different picture qualities among varying brands. I browse forums all the time and the only time ive seen the word SANYO come up being discussed is with their projectors, and their Z3000 is impressive.

Riff Magnum · 07-16-2009, 05:50 PM

He got a 42" 1080p LCD for $500. I'd say that's a pretty good deal and i'm sure the picture is fine.

OP, you might try and check out www.avsforum.com and type in your model number and find an owners thread about your model. Maybe there's a tweak you don't know about or other owners have had similar problems and found a way to minimize it.
I know on my set there has been much discussion about how to set the ps3 and the tv's RGB level. Some people say if you mostly watch movies to set the ps3 to limited and tv's rgb to low to achieve better blacks. Others say if you play games mostly that the tv should be on normal and the ps3 on full.

Does your Sanyo have individual controls for backlighting? If so, I would suggest turning it down. It sounds like there could be some light leakage that becomes more apparent on the darkest scenes?

Ubermod · 07-16-2009, 06:25 PM

My guess is that it would be a signal clipping issue. Video black is 7.5 IRE and with lower end video monitor, it might completely square anything below that which could manifest itself as blue splotches. Just a thought.
