I am using two LG 4K monitors connected by HDMI to a Sapphire RX580 Pulse. OS is 10.15.2. SMBIOS is MacPro6,1. Lilu and WEG are most recent versions being injected by newest release of Clover. The monitors will not wake from sleep and stay black after the system sleeps. After much banging my head against the wall, I have learned I need to disable AGDC. However, the output from "ioreg -lw0 | grep CFG_USE_AGDC" is "CFG_USE_AGDC" = Yes. AGDC is still enabled which causes the 4K monitors to not wake from sleep.

The release notes for WEG 1.15 state "added automatic CFG_USE_AGDC disabling to avoid constant issues with 4K display sleep and broken HDMI/DP ports".

Confusingly, the manual under says:

"Why can a highres DisplayPort-connected display fail to wake (e.g. some LG 4K models)? Sometimes AGDC configuration preference could be the case. For 4K and lower it makes sense to try disabling it by passing CFG,CFG_USE_AGDC — False (00) via SSDT or similar."

What am I doing wrong? Why isn't WEG disabling AGDC which "should" fix my 4K wake from sleep issue? Do I need an SSDT even though the release notes say it should be done automatically? I have tried (and failed) to make an SSDT to disable AGDC.
