I'm running into some difficulties partly because the guide is older than the newest version of DispcalGUI. I just have a few quick questions:

- Enable "disable 3dlut"
Is the aforementioned still necessary?
3. Set the following settings in DispcalGUI[LIST=1][*]Select 'madVR' under Settings[*]Select 'madVR' for Display device[*]Select 'Rec. 1886' for Tone curve[*]Disable Black point compensation and Smooth B2A tables. Enable Low quality B2A tables.[*]Click on 'File' on the toolbar, select 'Edit testchart...'[*]Use the options in the testchart screenshot below for a basic 2000 patch set. (You can adjust the pattern set parameters based on your display response behavior)[*]Click 'Create testchart', click 'Save as...' and save the pattern set to a location, then click on 'Select' when prompted to use the created testchart.[*]Click 'Calibrate & profile' button. The duration of the process will depend on the speed of your meter.
Selecting Rec.1886 sets the the settings back to default. Should I leave Tone Curve alone (default)?
I cannot find Smooth B2A tables and Low Quality B2A tables.
Do I still need to edit the test chart? Why can I not just increase the slidder?
What does it mean to adjust the parameters based on display response behavior? I'm practicing right now on my laptop screen before attempting this on my main living room theater LCD TV.
4. After the process is complete, go to Tools in the menu bar and select 'Create 3D LUT...'
Is this still a necessary step? I looks like "create 3dlut after profiling" is already checked.
5. Set the following settings for Create 3D LUT tool[LIST=1][*]Select 'madVR (.3dlut)' for 3D LUT file format[*]For Source profile file, browse to the Rec709.icm file from the 'ref' sub-directory in the program path of ArgyllCMS[*]For Target profile file, browse to the .icm file created from the profile process[*]Enable 'Apply calibration (vcgt)'[*]Enable 'Apply BT.1886 gamma mapping' and select '2.4 Absolute'[*]Select 'Absolute colorimetic with white point scaling' for Rendering intent[*]Click on 'Create 3D LUT...' button[*]Provide the filename and location to save the 3DLUT
Again, forgive my ignorance but I'm having a hard time here. Is it because this is outdated? Isn't this tab already checked to run?
C. Apply the 3DLUT file in MadVR[LIST=1][*]Play any video file in a media player with MadVR set as the video renderer[*]Right-click the MadVR tray icon and select 'Edit madVR Settings...'[*]Expand your display device under the devices node[*]Select 'calibration' menu[*]Select 'calibrate this display by using an external 3DLUT file'[*]Check 'disable GPU gamma ramps'[*]For the BT.709 field, click the browse icon and select the 3DLUT.3dlut file generated
When I entered this it appeared that the 3Dlut was already loaded. So I shouldn't have to browse for it correct? Also, what does "disable GPU gamma ramps" do? Is it still necessary to disable?
Thanks for all your hard work in making this guide. Is there an updated guide somewhere that I should try?
Also, doesn't running through the test supply a profile that Windows can use for desktop? I'm noticing the same results in HCFR before and after profiling (unless I check use madTPG).
On a side note, the CIE results look pretty good when checking use madTPG in HCFR, however, dE for all the colors during a 10 point saturation sweep are around 10dE. What also was weird is that the gray scale test was awfully brown, but it yielded an extremely low dE (like below 1dE for all 10 points). Is the unusual brown during gray scale test normal?
