Anyone tried creating a 3D LUT for a JVC DLA-HD990 with any pre-3D Lut calibration tips? Seems these projectors need a LOT of patches due to the non-linearity of the CMS - even 4500 is not enough for these beasts. Running this many does help, but there's a lot of work still to do. There is certainly enough colorspace for the LUT to work - the 100% points can be set perfectly, or one can try calibrating to 75% instead - both methods have knock on effects at the inner points however and the errors are large enough to be visible. Any tips appreciated. Currently trying to do as little as possible with the built in controls.
