I am desperately trying to calibrate my Sony BVM-L231 (http://www.pro.sony.eu/pro/lang/en/eu/product/broadcast-products-professional-monitors-lcd-production/bvm-l231/overview/) with dispcalGUI but I don't seem to get acceptable results.
After that I load the LUT into Resolve to see that the LUT doesn't look right. Its clearly washed out and I see noise and artefacts all over the place. This is the original image before applying a LUT: http://i.imgur.com/0jeT1aa.jpg
And this after applying the LUT (please notice the red noise and artefacts on his left cheek): http://i.imgur.com/AZKiDxR.jpg
Am I doing something wrong? Are my settings right? I just can't believe that my Sony BVM-L231 grade A reference monitor is displaying colours that wrong.
Please help!
Best,
Chris
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Generally I recommend to not do grayscale calibration (set tone curve to "As measured"), especially with instruments like the Spyder4 which are rather slow and less accurate near black.
The calibration process takes about 5 hours and after that I get a tone response curve like that: http://i.imgur.com/HzIz6lR.png
To get a representation of the curves used for the 3D LUT, you have to switch to "Device <- A2B <- PCS".
And this after applying the LUT (please notice the red noise and artefacts on his left cheek): http://i.imgur.com/AZKiDxR.jpg
Please attach the profile "Resolve 2015-02-23 2.2 S XYZLUT.icc" so I can take a closer look.

Thanks. It seems you have not used the "Resolve" preset (under settings), and the minimum display update delay for resolve (600ms) was thus not set. There are several misreads in the measurements due to that. My advice would be to start fresh from the "Resolve" preset, and make sure the minimum update delay is set (you can check this in the "Options" menu under "Set additional commandline arguments").

Hi,

Following this guide: http://sourceforge.net/p/dispcalgui/wiki/3D%20LUT%20creation%20workflow%20for%20Resolve/ I configure dispcalGUI like this: http://i.imgur.com/csqVxfU.png
The calibration process takes about 5 hours and after that I get a tone response curve like that: http://i.imgur.com/HzIz6lR.png
I proceed to the 3D LUT creation window and these are my settings:

Hey,
thanks for the reply. I just did another calibration with tone curve „As measured“. Same problem. Please find the .icc attached.
