[ilyalazutkin]

Can someone help? RX 6800 black screen if i turn off monitor. Guess wake up problem (If i insert cable to HDMI again -> monitor back view). Tryed USBWakeFixup.kext — not works, tryed CFG,CFG_USE_AGDC key in PCIlist in DeviceProperties (Also doesnt works). I dont have internal graphics.

If you turn off the monitor, why do you expect the monitor to display anything at all?

You mean if you turn off the monitor and turn it on again, you don't have a display?

Can you somehow argue and what is the basis of your so useful advice?

If that's the case, here are the issues

- SSDT-EC-USBX is for Skylake and above.
- SSDT-PMCR is for Coffee Lake.
- SSDT-RTC0 isn't required unless you have RTC issues.
- SSDT-CPU exists so why CpuPm and Cpu0Ist is being dropped?
- You're using SSDT-UNC as well as also using a UNC rename
- Kext sorting order is not correct.
- ASUS reports the SMBIOS normally. Not sure why CustomSMBIOSGuid is being used.
- You're using SSDT-RTC0 as well using a Kernel patch.

These are some main keypoints. Other than this, a clean-up is required for the whole config.plist as described in the guide.
