I have the RS400, connectded to a Marantz SR7010, with the HDFury Linker in-between to remove the HDR flag and prevent Gamma D auto-switching, and enable the DI. All my sources (primarily Phillips BDP-7501 for UHD and HD BD, with some Roku (Premiere+) connect to the Marantz.
I am encountering the problem where the Projector loses Sync at times, resulting in that odd screen with flashing colored lines. This was a known phenomenon with the Roku, possibly related to having CMD enabled. But lately, I am seeing it after viewing a UHD or HD Blu-ray, during the shutdown process (I use the Harmony Remote/Hub, controlled by voice with Alexa), when the disc is ejected, and before the Projector is turned off near the end of the sequence. It doesn't happen all the time, and in a sense, it's not a problem, since it will be turning off anyway, but it bugs me. Plus, if I wanted to watch something different after, I might have to power cycle the projector.
(I don't believe it is from the HDMI Cable - this is a 25' 'PlugLug' cable from Amazon, no longer available, but with which I can watch any UHD blu-ray, including the 60Hz torture test of UHD of Billy Lynn. No glitches during playback. It's just this odd, occasional corruption of sync after I watch something.)
Anyway, with that as an introduction, I was thinking about how to eliminate this, as well as eliminate the frequent 15-20 second HDMI sync lags inherent in the JVC. What I'm considering is configuring the Marantz AVR to output 4k/24 Hz all the time, regardless of the source. Since I mostly watch movies in there, I'll end up with 24 Hz anyway.
Is there any downside to doing this? I'd think it would likely eliminate the problem I intermittently have, as well as eliminating pretty much all the delays caused by the prolonged HDMI sync of the projector.
