At least right now Dolby Vision seems like not a problem to deal with. As I've mentioned earlier, my plan was to use an Nvidia Shield TV to stream PC games to the TV and watch other 4K stuff via Netflix. The Shield TV specs do not mention Dolby Vision at all, so I'm assuming it's going to be HDR10.
HDR is really confusing right now and it's hard to get a good setup done. LG seems to be doing a good job supporting as much as possible on their TV, but AV receivers are an issue now.
RX-A1060 is
really expensive and seems to come with two HDMI Outs and eight HDMI Ins but I don't need that much! Only need three inputs for PS3, PS4 and Shield TV. I'm fine with 5.1 speakers too.
One I was interested in was
HTR-4069 which is much cheaper, but the only mention of HDR is buried in those specs as "HDR Video".
