About MadVR with ArgyllCMS 3D Lut calibration and settings...

[shaolin95]

Hello all!
First time I am able to get my Colormunkey Display to work with ArgyllCMS so I did the calibration yesterday for my BenQ W1070 but I got some questions to make sure I did the right settings for my requirments.

Questions about the steps found at AVSFORUM post:

#1 Set the following settings in DispcalGUI

Select 'madVR' under Settings

I do NOT see a madVR option on the Settings drop down menu. I do see it under Display drop down menu so that is where I selected it. Is this a problem or just a difference on how the current version works?

#2 I did not see a Enable Low quality B2A tables as per the original guide but looks like by selecting MadVR this is done automatically....right?


#3 When creating the 3D Lut, I did not see the Enable 'Apply calibration (vcgt)' option as per the original guide. Problem here?

#4 Not sure but does this calibration affect the normal black and white level settings, thus I need to recalibrate after this? I am going to check tonight but just curious since I am at work right now.


Ok so now, this is my setup to see if I need any special options and to re-run the calibration.

Nvidia GTX 750
Windows 8.1
Using MPC-HC with latest madvr.
BenQ W1070 DLP projector. I was running Gamma 2.6 on the projector settings in a pitch black basement with partial ceiling and walls covered in black velvet fabric. Floor has a black carpet.

I watch exclusively ripped Blurays with MPC (except for 3D ones which I watch with PowerDVD).

Yesterday it finished after 1AM so I was too sleepy to test much but a quick Avengers check seem that it was a more redish look to the faces etc. Of course could be that my current one is too blue so I need to test more tonight but I want to make sure I did not miss anything since it seems the original Guide is a bit outdated.

I will appreciate any feedback.
Thanks!

which version of dispcal GUI are you using there?

which version of dispcal GUI are you using there?

I am not home to check unfortunately but it must be 3.0.1 as that is the latest and I just installed it yesterday.
For Windows XP or newer under the section there called "Get dispcalGUI via Zero Install (recommended)"

under settings take ~"video 3d lut for madvr"

you can ignore the b2a table they don't matter for a 3d lut.

i can't test the 3d lut part right now.

1. it should have a setting called video 3d lut for madvr. (else you can find it at \Program Files (x86)\dispcalGUI\presets)
2.does not matter, was used to save time iirc
3.my experience is that vcgt usage depends on the display. If the display's whitepoint can be calibrated using slider/osd then it does not need to have calibration from dispcal and thus not need vcgt. though now dispcalgui have a linear curve emb in it iirc.

For you to access the vcgt option, you need to run the 3d lut maker from shortcut or in dispcalgui folder.
4. if you did not choose a toner curve in calibration , it should not alter the white level much if at all(since no dispcal calibration is actually done). If you followed the guide and pick srgb, the white level may get lower depending how far is the whitepoint initially. For black level, it should always try to keep it low, not sure how much it change though~

You can always use the verification page to generate a measurement report.

It would probably better to discuss further over at the avs forum, since fhoech is more active there , and he knows better (ofc).
