Ok, after doing today's supplemental update, it's still functioning, but I no longer have 4k@60hz. I had already changed the setting in the Dell menu to enable it, and 4k@60hz was working fine on Mojave and even Catalina before today's update.I'm not having this issue with a P2415Q connected HDMI->HDMI. Also have an Apple Cinema Display connected via DVI->USB-C.
But my displays never sleep no matter what Energy Saver settings I use.
I'm receiving an DP->USB-C adapter tomorrow to try to see if that fixes it.
