Hi, i have Epson TW7400. Awesome performance. Now iam trying to run HDR content and iam little confused. Source is from Windows 10 HDMI 2.0a Colors set to YCBCR 4:2:2 / 4:4:4 tryied too 10/12bit HDR on windows set to ON. Its working somehow - but dont know if working as supposed to. Projector is saying its receiving BT.2020 colors - 12bit, HDR enabled - it swith automatically. Picture look different from SDR but cant tell if its better at all. When playing for example Avengers Infinity from beginning scenes the comparison between 2160p HDR source MKV VS 1080P SDR source MKV is : HDR look dimmer - contrast is maybe better, but cant tell because its overall dimmer image, its not shining that much as SDR source of the same movie - colors are not that bright and vibrant too. In scene where there is shining star behind you can see details little better around...but...thats noticable only whnen focusing on that spot. SDR content have much more punchy colors - its obvious from the first moments of the movie and much more noticeble than "maybe better" contrast Dont know iff iam missing something and HDR not working as supposed here..? I was thinking HDR should have better colors? HDR change enable/disable is very much noticeble when playing HDR MKV with HDR off and after that you enable HDR. With HDR off the image is washed out complettelly like in FOG, when enable HDR you got some colors back, but again - VS SDR source in SDR mode theres much more colors presented.
