+1...Understatement of the year! (we only just started 2017 so that's not too bad)
What I find really silly is how often people want to upgrade static resolution but...hey, guys, we have had the capacity for 60 frames per second for 3/4 of a century on televisions, but movies still haven't caught up.
A 1080p movie shot at 60 frames per second would look far, far clearer, on current 1080p projectors, than a UHD Bluray at 24 fps on a UHD native projector, for any scene with motion in it, especially if the 1080p version included HDR and WCG as well. Plus, it would STILL cost less bandwidth. Our eyes use temporal supersampling at 83hz and if we had 120 fps video it would effectively double our static resolution as well. (noise and specular highlights moving around the image).
1080p / 120hz in terms of raw bandwidth is the same as UHD / 30hz, so slightly more than 24p. But compressed in HEVC? You could fit probably 2 1080p 120hz streams in the same bandwidth as a UHD 24p one, and it would look far better and clearer. Higher framerates compress far more efficiently than the same % increase in static resolution, hence it's a more efficient parameter to exploit.
There's a comparison on homecinema.fr of native shots at 1080p vs 2160p at various framerates and 1080p60 looks clearer than 2160p24 as soon as there is ANY motion, and once you go up to 60p or 120p there is a night-day difference in sharpness and clarity and realism.
I always laugh at the idea that we "need" UHD for sharper images, when HDR and HFR offer way more bang for the buck and HFR is ALREADY built in to literally every single consumer display device created in the past 75 years, it's just we don't use it. On purpose. And 60p is well within
the "capability of most media services and infrastructure" as you put it, it's just not exploited.
The main reason I want to upgrade my projector is for HDR + UHD Bluray compatibility. I'm fine with 1080p native resolution, which I consider the JVCs to be. It's kind of moot worrying about 3D crosstalk performance on JVCs being poorer than DLP, if these new DLPs don't even offer 3D whatsoever. But the saving grace here would be a UHD DLP that can accept 1080p at 120hz so I can use IR based LCD shutter glasses for 3D and send the material in a frame sequential way (probably will have to buy a 3D video processor though, but 1080p ones should be fine since 3D Blurays are only 1080p).
