On the Panasonic VT50, I've found that the 5% APL with 18% surround to work best. With the VT50, using a 5% window pattern at 10% level, the pattern is presented lighter probably having something to do with how the panel' power supply works. That causes corrections to be made to lower it. Switch to a 5% APL pattern and you see a significant difference. It translates into content by either crushing or not crushing darker shades before going into black. Some calibrators will still use a windows pattern yet lower the gamma for 10%.
My disc will work with any software that utilizes a round nearest method and/or software that assumes integer percentages. ChromaPure falls into this category and HCFR can be setup for compatibly. However, I am not sure if CalMAN's engine is adjustable to match my disc's RGB triplet rounding method.
That is for patterns at full saturation and CalMAN uses the same rounding assumption. For less then full saturation (saturation sweeps and the ColorChecker) the patterns match what ChromaPure is using.

I've been using a 7.5% pattern as the resulting gamma of 2.3 is almost identical to the native gamma.
With that said, I'm not certain that there isn't a better pattern. I've heard 5% with a 25% surround but that seemed a bit extreme.
Jim, do you see any difference at all between using 6.5 and 7.5% windows?
Also, what Cell Light setting do you use on the Samsung?
I'm using a signal generator and used the 7.5% since it was one of the standard sizes.
I wouldn't expect to see any difference between 6.5 and 7.5%.
Sorry, I currently offer no package deal options. However, I might consider an iso and mp4/mkv combo in the future. Yes, the H.264/MPEG-4/AVC is the mp4 file version(no chapters). The newest addition are mkv files with chapter navigation.
P.S. You can pm me or contact me via email from the contacts page of my website if you have any further questions
I will be releasing a Bluray disc version and updating my website soon. Unfortunately, it was bumped to the bottom of my priority list as I have other projects in the works.
If so, please kindly advise how best to arrange an exchange of material value for your work.
Just wondered, what is the APL and AL of the 4% APL patterns?
My 4% APL "EE" style patterns average around 22%. Here are two good threads to reference "APL primer" and "Patterns to measure MLL as a function of APL"
Utilizing MadTPG I would start with a 25%-30% background at 0% stimulus and step down incrementally towards a 13%-18% background until you reach 100% stimulus.
The 75% amplitude/75% saturation patterns within the color sweep are the same patterns used within the 75% amplitude saturation sweep. I pulled out the archives last night to double check triplets in both sweeps. What calibration software are you utilizing? Thanks!

Prior to measuring your saturation sweeps, did you select 75% vs 100% under "Select Pattern Intensity" shown below? This would cause what you're describing. Thanks!
