Thanks Justin
My set up sounds very similar to yours, Dreamcolor, Decklink Pro, HD Link Pro. I had thought my APS calibrator was faulty but now I think its actually the way the decklnk outputs video to the Dreamcolor. My problem is my blacks have no detail. Detail I can see on all my computer monitors and TV screens. I have the gamma set to 2.5 which is prescribed but if I look at colour bars where there should be gray bars in the pluge there is just a big fat black panel on the Dreamcolor. That’s not useful for my colour grading on Da Vinci Resolve.
I have been using the calibration tools properly from my Mac as you described the whole time but I’m still not confident with the picture contrast.
HP Support is totally useless. They don’t even know they have such a product. It took me three transfers and an hour before they found the APS device. I think they normally just deal with mum and dad’s Pavillion desktop PC and printer. Not a good company for professionals at all.
