Pro Display XDR

I have 3 pro display xdr's, mac pro 2019, w5700x, photography.

2 displays work fine. It will simply occasionally go black. It disappears from the thunderbolt bus but not always when blacked out. I've moved it from port to port, changed cables hooked to an m1 14 inch mac book pro, and when it's in failure mode it won't work in any of those situations. The workaround is.. leave it unplugged at night while not in use, fire it up next day and will run for hours. Other strange behavior when in failure mode is that if one hooks it to say an ipad off one of the usb-c ports to charge, the charging goes on and then off, and then on, and then off, weirdest thing you ever saw. Took to genius bar, and of course with intermittent nature of issue, it didn't reproduce there as it was off power for a while. I'm tempted to do a video or something. I run them in the photography- d65 reference mode, etc. So repeating, highly intermittent, goes away apparently after being off power for several hours and then can run all day perfectly fine. Help especially since intermittent. BTW, all running latest firmware and I'm running Monterey 12.3, after all I've done, it's clear this is an intermittent issue with the display itself. Worse kind of problem, not easily reproduced.
