Hi @CaseySJ, it's been a very long time since I visited this forum, so I'm sure you already forgot the issue I had. Basically, at one point my hackintosh stopped being to able to wake from sleep (even though it worked seamlessly for about 6 months). Among your numerous suggestions, you proposed to try USB C to HDMI cable (I was using HDMI to HDMI) but I didn't have it. I finally got two of those, but unfortunately, monitors don't seem to be connected when I simply connect any of my monitors (the monitor indicators just keep on blinking). So my question might sound really dumb, but do I need to do anything else apart from just connecting the monitor (HDMI) to the video card (USB C)? I was under the impression that it's just plug and play.You can also try using the on-board HDMI port or the two on-board Thunderbolt ports to connect your monitor. In this case we would need to do the following:
- Try a different video cable. Always preferable to use a certified HDMI 2.0 or DP 1.2/1.4 cable.
- If that does not help, then we could do the following:
- Set Platform ID to 0x3E9B0007 and add HDMI black screen patches. It's much easier to use a USB-C to DisplayPort cable or a USB-C to HDMI cable instead of HDMI-to-HDMI.
- If you want to try this, I can modify your config.plist (but remove serial number from SMBIOS section before sending).
- In BIOS, we would set Initial Display Output to IGFX.
- We would physically remove the AMD GPU.
- Now we can check if graphics look normal.
- If so, then AMD GPU is bad.
By the way, it doesn't work on Windows too, which is installed on a separate SSD, meaning when I turn on the machine from a completely shut down state, nothing appears on the screen(s). Does that mean my Radeon RX580 is busted or something is configured incorrectly in BIOS?
