No I don't. When I will be experimenting with downscaling 4k I will leave it in high lamp.You don't have to use E-shift with high lamp, or have I missed something there?

Maybe it's more noticeable with gaming, but neither myself or the other two people with me could see a difference in detail on moving picture between 4k eshift and downscaled to 1080p. We used a ripped UHD of Lucy. I'm sure we may have seen differences if we did a side by side comparison with freeze frames. Of course, it's also possible that we could just be lucky not to be blessed with the sharp eyesight you haveI use e-shift for 4k material on my X7900, there's definitely an uptick in detail, running a Gaming HTPC I really notice it with 4k gaming.
When I think about it I actually tested downscaling with MadVR of 4k to 1080p and I concluded that I preferred e-shift to MadVR's downscaling (but in general proffered native unaltered signal so 1080p for my JVC so normal BDs).Maybe it's more noticeable with gaming, but neither myself or the other two people with me could see a difference in detail on moving picture between 4k eshift and downscaled to 1080p.

I definitely see the benefits with films too, most particularly film shot catalogue titles of films I'm very familiar with, the one that springs to mind is The Shining's opening driving sequence which shows detail that is a clear step up from 1080p. Other examples are film sequences where you have fine line detail in the background such as chain-link fences, overhead telephone wires, etc.Maybe it's more noticeable with gaming, but neither myself or the other two people with me could see a difference in detail on moving picture between 4k eshift and downscaled to 1080p.

Might have got the setting name wrong, it is the HDMI setting in my Marantz that doesn’t play nice with the new drivers (4K Enhanced or something similar).Isn't enhanced HDMI just PC levels (0-255) rather than limited (16-235)?
I can share my MadVR settings if that's useful, what version are you running?
Interesting. I'm not sure what the max capability of the 7900 is but it seems like the Marantz will be doing some upscaling to specific chroma and bit depths that the JVC doesn't like. This might be fixable.It is this setting in my Marantz: 4K Signal Format AV8805
If I put it on 'Enhanced' I get no image from 4K films in MPC with MadVR. All starting going wrong a few months back with Nvidia drivers. I think it may be related to the Magenta Bug. I have just turned it off for my sanity.
I don't know my Peak Nits, do I need a piece of equipment to measure? (Happy to pick this up in the MadVR thread).
It all worked swimmingly well up until a few months ago and I updated my RTX 3080, I think it is the Nvidia drivers, but I also use the PC for gaming, so don't want to roll back.Interesting.

If you install LAV Filters as well as MadVR you should be able to choose the chroma sampling of the output. You can start with 4:2:2 8 bit and move up from there. The higher the bit depth the more bandwidth you need, so it might be limited by the ports in the PJ. The manual suggest support for both 4:2:2 and 4:4:4, but not what bitdepths those are supported at.
It's also worth looking in the JVC menu and checking what colour space the PJ is set to, it should be auto. That's in the picture adjust/input signal menu.
