This is competition that is not good at all for those wanting to get a new HDR display. This year I'm looking into getting a display for around $6,000. Two possible routes: 1) a 77" OLED when the prices drop towards the end of this year and beginning of next year, or 2) A midline JVC projector.
When I buy a display I want it to last 10 years or so. In fact, I am at about the 10 year mark with my Pioneer Kuro and up until the last couple years, there was nothing that really bested it in performance in a light controlled room. The LG or Sony OLEDs will not support HDR10+. They will do Dolby Vision and HDR10, but I would be missing out on the dynamic metadata from HDR10+. In fact I am not aware of a display that can do all three. Then there is HLG, which we need for (probably) broadcast television for the most part. At this point if you go with an LG or Sony OLED it won't have HDR10+, so you will be missing the opportunity to see the Amazon Prime content in its fullest potential. If on the other hand you go with a display that can do HDR10+, then you will miss out on the much deeper Dolby Vision catalog content from Vudu, iTunes, UHD Blu-Ray, etc. This is ridiculous that it has been two or three years now and not a single display can do all HDR formats.
Then you get over to projectors and you can only get HDR10 and HLG in some HDR projectors. It seems like they are going to try to guess at different brightness levels through processing to try to get the best picture out of it. Almost trying to do what Dolby Vision or HDR10+ would do without the dynamic metadata. I understand the reasons why with the many more variables in a projector and I'm fine with it. But, they are further behind with HDR implementation with projectors that flat panel displays.
Bottom line: I'm sitting here ready to spend $6000 on a good HDR projector or HDR flat panel that will have all of the formats (codecs) necessary for 5 to 10 years and I don't feel confident that any such display exists right now. I would love to get a new HDR display and start enjoying the improvement in picture quality, but I'm not an early adopter. It still feels too much like we are STILL in the early adoption phase. So I'm instead going to spend my money on upgrading subwoofers and maybe get an Atmos receiver with some overhead speakers. As long as I get a receiver that has HDMI 2.1 boards, I think it should be good for hopefully 10 years.
