People seem to think that HDR is more important than the higher resolution... and I would have to agree
My JVC X5000 is fake 4K, after all
The naming of SDR/2020 gets confusing, it's still HDR. Here's the background:
all projectors require some form of tone mapping with HDR content. it either occurs at the source (Panasonic UB820/9000) or at the projector itself with it's built in HDR curve or a custom uploaded curve. The goal is still the same and the Panasonic does an excellent job, especially when compared to JVC's first attempt (Gamma D) and even later version of it on the 420/440 models.
There are several advantages letting the Panasonic doe the tone mapping. It can select a specific curve based on meta data that is sometimes present on UHD titles. If a specific title doesn't have that data, it defaults to a standard curve that is still quite good. It also allows the projector to use the DI with HDR content with the SDR/BT2020 mode.
The next level of HDR tone mapping is with an HTPC + MadVR which allows for dynamic tone mapping. a process where the software is constantly adjusting for optimal visual appearance per scene. Ideally one day projectors will have this built in, but today it requires a powerful graphics card to handle this kind of constantly changing workload throughout the movie.
For those that want set it and forget it, the UB820/9000 tone mapping is a blessing that would have been welcome if it was released several years ago when the JVC's first released this series with HDR capability. Better late than never
