My offer still stands to do a free calibration and HarperVision on a 5040 so I can get the CMS and Greyscale readings.
Tell me about it Dave! I'm so frustrated. I did ask him if he done one of these and he said he has done plenty. His other customers must not be as critical as me then, or they simply have no idea about 4K HDR.
I did tell him about your Harpervision as it is stored in my presets and asked him to do a CMS calibration on it, but he just kept saying 'your Epson can't do 2020 colour, so we can't do it'. He said 'It doesn't do a good job of WCG so you're better off calibrating for REC709 instead'. He said it didn't matter which method I used to play HDR content, whether it was Harpervision or using the Panasonic SDR2020 conversion, it didn't matter because the Epson cannot do 2020 colour correctly, so he wouldn't calibrate for it.
He tried to explain to me and basically said that the Epson in 'HDR mode' only achieves a bit more than REC709, so if he were to calibrate in that mode the colours would be grossly undersaturated, particularly the green as it doesn't reach anywhere near where it's supposed to for REC2020 colour, so he calibrates in REC709 instead.
I said that sounded odd as I've read of loads of people online calibrating this projector for WCG with great results, but he didn't really have much to say. just wouldn't budge and I didn't want to be rude.
Is there any truth to what he said? I feel like I'm back to square one now, so with an 820 I'm trying to get the best picture possible on this projector.
I wanted to ask, the calibration he did for me was done using Natural mode. he forced my player to output REC709. Is there any point in doing this, since Natural mode doesn't use the DCI P3 colour filter anyway? Can I leave the UB820 in SDR2020 mode?
I will say that the colours of his calibration look great in Natural mode, but for now I'm still using SDR2020 with standard Epson settings using Digitla Cinema colour mode, as I feel like I may be missing out on the benefits of UHD discs otherwise. If I simply wanted to adjust brightness and contrast using SDR2020, which test patterns do I use? The R. Masciola ones, or those SDR test patterns from a few years back (forgot the name)?
Unfortunately I live in Australia otherwise I'd happily send you my Epson.
