Please bare with me as I am a beginner in this area of TV calibration and learning what all the options actually do to a TV's picture quality and perfomance.
About a week ago I picked up a Samsung UN46ES7500 and have used AVSHD 709 to do basic calibrating on all three HDMI sources.
All looks fine to me as far as my eyes can tell. When it comes to setting HDMI Black Level - "Normal" or "Low" to finalize calibration of my HTPC (HDMI1/DVI - DVI Devices mode) I am confused on which option setting is correct to use.
From reading other posts I am understanding that "Normal" is RGB 0-255 and "Low" is YcbCr 16-235.
When viewing my Desktop and movies while toggling between Normal and Low - I feel that Low gives me a much better picture quality overall. The blacks are deep blacks with grey shades of shadowing detail, I don't think I notice black crushing. Where as Normal gives the entire picture a grey overlay washed out appearance to every color not only shades of black.
The Nvidia GTX 580 Control Panel can be set to output either RGB or Ycbcr444. It is set to RGB at the moment and the HDMI Black Level setting in the TV menu is now grayed out and the picture quality looks good like it does when I used to be able to set it into "Low". If I set the Nvidia Control Panel to output Ycbcr444, then the HDMI Black Level setting is no longer grayed out and I can pick between Normal and Low again. While Low still looking better to my eyes than when in Normal (grey and washed out).
So the standard is (correct me if I'm wrong):
RGB 0-255 color space (Full PC levels)
Ycbcr 16-235 color space (Limited)
Samsung LCD TV's HDMI Black Level:
"Normal" = RGB 0-255 ??
"Low" = Ycbcr 16-235 ??
Ok, now as for what the Subject line is all about.
I have come across a few posts in similar threads that mention that years ago, Samsung (made a misake) mislabeled the HDMI Black Level choices (Normal and Low) in reverse/backwards and haven't corrected the issue, even though their QA Department requested for Samsung to fix the labeling. (??) I've googled about this and could not find any official word from Samsung. Maybe Samsung got lost wording the labels in translation by converting what it means in Korean over to English. Also, back then Manufacturer's were getting mixed up and confused when HDMI constantly changing/adding new technologies and standards with their HDMI revisions.
If it were backwards labeling then it would be like this:
"Normal" = Ycbcr 16-235 ??
"Low" = RGB 0-255 ??
So my main question is, has ANYONE heard about this "Samsung HDMI Black Level Mislabeling"? Anyone know if it has been fixed in their TV's?
Appreciate your thoughts and information about the subject.
BTW just received the Disney WOW Calibration DVD and can't wait to check it out! Oh and the TV is pretty awesome too!-continued in Display Calibration forum-
