Ok so you mean i should use the 10 % pattern to match 120 nits even if its getting lower in 100% afterwards? Cause this could be easily done 😉
2016-09-04 at 16:18 #3947Next round finished but still kind of bad 🙁

2016-09-04 at 20:24 #39532016-09-05 at 0:58 #3957The profile looks fine, not sure why you think it’s bad?
2016-09-05 at 9:57 #3958No i thought the report should be ways better ? I can point at black level quite sure for now… something must be wrong here.
I guess the .icm s are used to calculate the 3DLut ? Maybe i just did not get how that works so far 😉 So what are these profiles for and how should an ideal or almost perfect report look like? I thought the dE should be as low as possible as they should be after a normal calibration?
I have tested a movie yesterday and accidently forgot to remove the Lut from madvr… right from the start i recognized the washed out elevated blacks. Removed the Lut and black was black again. So something must be wrong but i rechecked the levels with patterns using MPC-HC which uses madvr and they seem to be correct. Also i am not sure if the madvr pattern generator uses these settings as well which i would assume. Besides that i recongized that i enabled to disable the internal gamma table of the graphics card …maybe this is wrong as well.
2016-09-05 at 10:06 #3961Ted “from” Ted’s disc just told me madvr should show 0-255 instead of 16-235
I thought madvr’s output should match the TV’s expected input level?
In order to have as less conversions as possible while preserving BTB and WTW.
So:
madvr: 16-235
GPU: 0-255 to get TV levels passed through
TV: 16-2352016-09-05 at 15:31 #3967madvr: 16-235
GPU: 0-255 to get TV levels passed through
TV: 16-235In theory it should work that way, but the raised black level in your case seems to indicate that something is wrong with the levels setup somewhere (either in madVR, GPU or TV settings). Personally I prefer having GPU at 16-235 and madVR at 0-255 for my TV because I want (and need) the Windows desktop to look correct.
2016-09-05 at 17:48 #3969What is strange is that HCFR with madvr and same settings seems to get the blacklevel correct if can read the chart correctly:

Also i am not sure if the madvr pattern generator uses these settings as well which i would assume.
You should check that.
2016-09-05 at 19:42 #3972Btw, I hope you’re not using dispcal’s/dispread’s -E parameter, are you?
2016-09-05 at 19:47 #3973Odd target ? Whats the -E parameter ? I am just using the settings for Rec.709 as shown i Displaycal… at least i thought so….
2016-09-05 at 20:24 #3974wow something else is weird as well but might explain why the reports seem to be so bad…
Does displaycal deactivate the “disable 3DLut” feature while verifying?
I have just deactivated it and the report was ways better….if this is the issue the its sitting in front of the computer. Just to be sure can you let me know the settings for madvr patter generator that should be used/enabled or disabled for profiling on the one hand and verification afterwards on the other hand?
Anyhow still black is meassured as Measured black luminance: 3.5928 cd/m² which is obviously not correct.
I have attached the latest report…

It didn’t seem to be BT.1886 or any of the common gamma targets (2.2, 2.35, 2.4…) because those would have different target Y values.
Whats the -E parameter ?
The -E parameter for dispcal/dispread makes them use video levels. Note that this parameter should not be used with madTPG. You can check under “Options” -> “Additional commandline arguments…” in DisplayCAL if you accidentally entered any commandline options at some point in the past.
Does displaycal deactivate the “disable 3DLut” feature while verifying?
If “Enable 3D LUT” is checked on the “Verification” tab, yes.
Just to be sure can you let me know the settings for madvr patter generator that should be used/enabled or disabled for profiling on the one hand and verification afterwards on the other hand?
You shouldn’t touch the enable/disable videoLUTs/3D LUT buttons in madTPG. The correct state will always be set by the connected software (HCFR/Argyll etc.).
2016-09-06 at 8:40 #3983Thats really odd… cause i did not change anything but choosing BT.1886 2.4 within displaycal/hcfr and the TV is set to gamma BT.1886 as well. Do i need to have GPU gamma ramps enabled cause i have them disabled in madvr settings itself.
Ok so displaycal enables the Lut for verification and disables it for profiling – is that correct?
