I would think using a UHD player into the HDFury "Linker" going through a Moomi card would get HDR 10 or 12 deep color into a CRT projector at 1080P resolution. It has been years for me and CRT can a CRT deliver 10 or 12 bit to the screen? If so you should be golden.
i dont even know of any Digital projectors capable.
Using the Linker will alow you to maintain 12 bit deep color setting the output of the player to 1080p does not.I do not have a CRT for testing so my comments are theory based on my experience so far with HD10. I have to take your word that HD10 via CRT projection is to dim, I would think CRT would be the perfect platform to how off HDR. OLED would be the next closest display to CRT and not as bright as LED or Lcos but it shows the best HDR to date. Maybe Dolby will fair better. Glad to see someone give HDR a try, good work.
My JVC RS600 doesn't seem bright enough for HDR, let alone a CRT projector !
I know there is a gain to UHD SDR if you can hold a perfect black and a 60fl output, but no CRT will ever get there, i dont even know of any Digital projectors capable.
