My settings using the 3080 video card if anyone wants to see, so simple and easy to setup.

Hi Murray,
Thanks for your settings. I have an ISCO IIIL A lens as well and will try your geometry settings. I only noticed that at the most left/right of my screen that the lens is not giving me super sharp focus but looks fine in the centre.
Which tone mapping algorithm are you using in the JRVR setup? For me, for best details without blowing my white levels, I'm using BT.2446a. One of the others gives me a brighter picture but at the expense of clipping my whites. My projector has been calibrated to the DCI colorspace so I'm using DCI-P3 as my screen gamut.
I'm using a runco Q750 paired with ISCO IIIL lens on a 103" 2:35 G3 studiotek. Picture looks amazing, it's literally set and forget. Was really sick of madvr continually tweaking.

as noted before, you're outputting rec709 for UHD content which is a smaller gamut that is on disk so you're compressing into the smaller gamut = not ideal.
you're also checking the 10bit output box which I'm not sure is the right choice for a JVC projector, my recollection is that this leads to some further processing in the JVC but I think the correct answer on this depends on the settings used on the projector (memory says you can use 12 bit if in low latency mode otherwise should use 8 bit). The correct setting here will be buried on one of those mega threads on avs.

Murray seems to have "Auto" selected for Gamut. Should that not keep the Gamut untouched?
Hendrik:
Auto is basically BT.709 (for SDR) since information what your screen expects is not really available right now, unless you use an ICC profile which contains that information, which overrides all those settings.
