I'm seeing the same thing on the latest firmware. I tried setting the reboot timer to 12 as suggested, but that didn't work. I checked the TX display this morning before I turned the system on and it showed the RX in PowerSave mode. The RX seems to get locked up coming out of power save, since the TX shows it connected but the RX shows no signal. For now I've disabled LINK POWERSAVE in the RX config, and will check again tomorrow.Every morning when I get up and turn on my TV, the RX is saying no signal even thought the computer is outputting and the TX is showing its getting and sending a signal. A reboot fixes the issue and everything will work fine all day long (even on reboots/computer going to sleep/anything). Just a weird quirk I'm trying to figure out.
And a 2nd issue: I just loaded the newest firmware this week and nothing would sync until I switched to EDID 11. I had the "Full + BT.2020 LLDV" EDID loaded in slot 10.. I did the normal export config, load firmware, import config procedure on both the TX and RX. The TX would display the received signal, then no signal, and repeat every couple seconds with it on custom EDID 10. Reloading the "Full + BT.2020 LLDV" EDID into 10 fixed it.
