I’m running CE (nightly_20201011 ng) off a microSD card in a Tanix TX3 S905X3 box connected to a LG 4K OLED TV. The weird thing is that using Power -> Reboot from eMMC does reboot back to Android (Slimbox v9) but the TV display remains dark unless I turn the TV off and back on or remove and reinsert the HDMI cable. Rebooting from Android to CE is fine.
Both OSes are set to display in 2160p
Any suggestions for what to look at will be greatly appreciated.
