There are two sides to a 3DLUT, the input and the output. The correct way is to leave your TV in DCI mode, not auto or anything else. Mainly my doubt is now related to what is correct to use while watching movies using BT709. I found a bit weird using DCI color space in TV settings then calibrate with madVR default settings with BT709, but I get that is done to take advantage of the wide gamut of the TV. Obviously, using an HTPC, when I'm not using madVR/MPHC this choice also influence the normal screens in Windows and other programs. Now in the end it shows that has been covered about 88% of the DCI-P3 colorspace (and like 124% sRGB), much closer to the professinal review you can find online.īut what now with madVR? I mean if I upload the three 3DLuts (BT709, DCI-P3 and BT2020) and leave my TV color space on "Auto" I understand it choose the BT709 also because the video info (ctrl+J) of madVR shows BT709.BUT if in the TV settings I choose DCI-P3 I have richer colors.ĭon't know what it is right (close to the reality) to choose.leave it on "Auto" and get the BT709 colorspace or choose the DCI-P3 and like take advantage of the wider gamma? Ok, calibration remade with DCI-P3 selected on TV and the madVR profile config in Displaycal, meaning BT7. Thank again for all the patience and support. Thank you again, your advices are precious.Ģ) "Auto" must have put your TV into BT709 (sRGB), try DCI if you want a wide gamut, but again you will need to completely redo the calibration for madVR. what's wrong? IF there is anything wrong. But in every review they say that after calibration the TV covers about 96% of DCI space. I could choose between Auto, BT709, BT2020 and DCI, I left it on "Auto" for the calibration and deactivated the backlight (the other pic processing were already off).ġ) My TV allow me to calibrate 10 point gamma, but I don't know how to implement/perform this with DisplaycalĢ) When the calibration has finished it showed a little report saying that the calibration (my TV) covered like 96% of the sRGB and about 66% of the DCI space. In the end I loaded the three profiles in the 3DLut page of madVR.Ībout my TV and the color space, I cannot choose a "Native". After that, from the same 3DLut creation page I created other two: BT2020 with Gamma 2.4 (absolute) and another one DCI-P3 with Gamma 2.4 (absolute). I followed everything and created my 3DLut with the Madvr settings. Thank you huhn and Asmodian for the indications. You newer touch the settings under "calibration" there is no need for that. you can use the tool 3DLUT maker to create more 3D LUTs it is part of displaycal so you have this tool already. creating a 3D LUt from these readings takes about 5 mins. This will create readings you can use for as many 3D LUT as you want. the default settings of ~1500 patches should be fine. i personal use ~13000 patches there is no need for so many but you have to run this only one time. Use a profiling setting you can leave with. that may be called BT 2020 DCI p3 or something like "native". If you want to use bigger colorspaces make sure your TV uses this native color space. Make sure you have disabled all picture processing stuff in your TV and that means you have to disable backlight dimming and stuff like that too! and leave the calibration settings as they are and that is as maesured. Select setting -> Video 3D LUT for madVR. So in calibration should I use 2.4 in tone curve or BT 709 or BT 2020? I know that I can create more 3D Lut but should I change the setting also in calibration or just in the 3DLut setting? I mean I understand setting gamma 2.4 in calibration and BT709 in the 3DLut page but if I need to create a BT2020 3DLut should I also change it in the calibration page?
