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%.
What do you recommend for the Samsung F8500?

Ryan

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.

Samsung 64F8500, Panasonic 65VT50, Oppo 95, Tivo Roamio for OTA, Dish VIP722, Marantz AV8801 preamp, Rotel Amps, Atlantic Tech 8200 speakers, Seaton Submersive HP, Calman 5, Chromapure, Accupel DVG-5000, i1Display3pro, i1pro2, eecolor colorbox.

ok, but are there 7.5% windows on Mascior's disk somewhere? I see 2, 4, 6.5, 10 and 15% windows and 2, 4, 5 and 10% APL windows.

7.5% patterns do not exist on my disc. However, your are really splitting hairs between 7.5% and the 6.5% patterns that I have available on my disc.

Yes, I would have assumed the same but...
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?

So I guess it is either round down or round normal.. what should it be for this disc?
I found this comment by zoyd: "Round down is what AVSHD,DVE use and round normal is what GCD and the internal generator use."

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%.

No package deals if you want several of the "disc" options? What format is the H.264/MPEG-4/AVC option? Is that MP4 files?

Hi Stereodude,

 

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:)
