(Read my post above).
Details Enhancement: For some detail enhancing, a Darbee or e-Shift can be used, to restore some details, which I don't believe it's so much loss (from 2160p -> 1080p downscale) since most of the UHD movies now are just an upscalled 2K master to 2160p.
There will be a lot of loss. Unacceptable as a solution I am sorry unless you can somehow get a 4k device rather than doing any downscaling. I understand a lot of films are 2k DI masters, but this really only from this point on applies to back catalogue titles, from this day forward probably 75-80% of all films will be mastered in 4k and this argument will no longer be valid. You would need to use something like MadVR before the final image enters the projector so the projector sees a native UHD Signal, but throwing away 75% of the original resolution, doing some tone mapping and then up-scaling the 25% version back to 100% is seriously compromised solution for what it is you are trying to achieve. You are cutting off your hand to spite your foot.
Go into photoshop, and resize a 4k image to 25% of its original 2160p resolution (1080p), save the image, close the program, reopen it, and then up-scale that image to 2160p and compare to the original, its going to look nothing like it.
Hi, I prefer better a lower resolution (but 10/12bit bit depth) and larger gamut (REC.2020) but accurate and calibrated colors of whole video signal (not only 6 colors from primary's/secondary's....but some thousands colors), so the picture will become more like-like and accurate colors gradations/gamma/depth than a native 4K uncalibrated signal with sun-burned faces and glowing grass etc....facts will not let you enjoy a movie playback if your are familiar with display calibration and calibrated colors.
If I resize @ 25% a 2160p still image it will give me a 960x540px image.
You can't use MadVR.since it's supporting only file playback (not live stream), you can't add a video capture card that captures 1080p video realtime to go throu MadVR etc.
Also if you want to feed the projector with 2160p, you can add another one HD Linker to the output of eeColor to upscale 1080p->2160p.
95% of the released UHD tittles are all coming from 2k masters, 2k masters are the ones you see @ theatrical releases, I don't see any problem with resolution with that.
I posted an idea, everyone has it's own priorities and requirements when he is watching a movie.
So from me who is watching movies with 3D LUT color calibrated system with about 10.000 colors from 2012, using my own lab-grade meters (see signature), it's more important the color fidelity than resolution.
I will like better a 1080p REC.2020 10/12bit than 2160p with tons of color errors, don't forget we are talking especially to a JVC which is not a native 2160p device.
Don't forget we are talking for what is happening to current HDR/UHD disk status, and what someone can do if he wants accurate colors now with current hardware and with limited gamut coverage current devices have.
