Fifth Method for Setting Color/Tint Controls - Preventing RGB (>255) Red Clipping
The following thoughts and method came about in order to compensate for the over-saturated Red primary color for my Panasonic TH-42PZ85 HDTV.
As previously mentioned in this thread I have calibrated my TV using an EyeOne (i1) Display LT using 3 other metered methods and the blue filter method. After much viewing of program material and research into color spaces, I found a very useful and informative site from Bruce Lindbloom. This site has many technical color tools...
The problem that I have experienced with the Blue filter method with my plasma and my older Sony XBR CRT TV's is that the color always ended up unnatural and way too much (too reddish).
I agree the probable cause may in fact be the over saturated primary colors. However, all the TV's that I own do not have CMS controls, therefore the only option for correcting (or more accurately compensating) the situation is too reduce luminance by an amount that reduces the negative...
No blue filter - just your eyes.
Just the static 75% SMPTE bars or for the THX Optimizer Test Pattern (that is really a row of color patches).
You are just trying to detect when the red becomes too bright with the Color control, then stop.
You may what to try and read additional thread comments and information about black level for various display types here.
This article helped me understand what was different about my plasma TV vs. my older CRT displays.
I was experimenting with my color settings and looking at related color information. This is what I found that might help you decide what is more correct for your TV without a meter. Use the THX Optimizer Color Bar (patch) Test Pattern on many DVD's or BluRay discs. The method that I tried that came close to a meter setting that I am using is the following:
1) Set the COLOR setting at the LOW end - for your case probably 40-45.
2) Look very carefully (darkened room) at...
It sounds like your eyes are in agreement with my measurements and my observations regarding the blue filter over-doing (too high) the color setting. The other observation that I have made is that there seems to be a broad range of acceptable color settings. Which one is right (best)? Without a meter I don't think it's possible, too subjective. However, the Color=52 setting might be close.
The one observation that seems to bother me the most is the amount of...
I understand you do not have a colorimeter. I have done some extensive testing of "blue filters" that I have from calibration discs on my Panasonic 42PZ85 plasma TV and this is what I found out.
The "blue filter" method will oversaturate the colors significantly. In other words the filter sets the Color control too high. In my case the filter setting was 46 and the metered setting was 40 [color range 0 to 100]. The filter set the Red color almost 40% brighter than...
This data is a subset of the HCFR data as previously charted (above) except that this data was entered into the ChromaPure dE, LSH and RGB Color Analysis calculator. The 3 sets of color data are for the following Color and Tint settings and methods.
1) Color=40 Tint=+2 => Red HCFR Luma Error set to 0%
2) Color=42 Tint=+3 => Red Luminance set to actual Larger Color Gamut calculated value
3) Color=46 Tint= -3 => DVE Blue Filter for both Color and Tint with Avia DVD...
You might be interested in the following article regarding Black Levels of various display types from DisplayMate.com. The article seems to place the DLP between the CRT and a plasma display for gamma.
