Hi hdmkv!
I also have an Optoma UHD51 projector. Yesterday I watched through an elementum on Vero 4K + movie in 4K HDR. The projector writes that it recognized the HDR but it is not in the picture. But on television, the HDR in the same film works fine. Perhaps there are some recommendations for a bunch of Optoma UHD51 and Vero 4K +? My 4K HDR films from internal sources also show incorrect colors. On the TV with HDR, everything is fine.

I used to have a UHD51A, but later upgraded to a BenQ HT3550. HDR 'should' activate just fine using either PJ w/Vero 4K+. Suggest trying a few local video samples vs. an add-on.
