This is normal for most displays with built-in speakers because volume has to be adjusted on the monitor itself (activate the monitor's built-in menu and it should allow you to set volume level).It's saying no output controls.
Very glad to see another successful build!@CaseySJ
I must say this is a great guide, I cannot thank you enough. I've just built this up but used a 9900K instead. Everything was/is working wonderfully. However, I've discovered an issue with booting straight to a 4K screen.
I initially did the whole setup at home with a 1080p screen. Everything was great.
However, I've just taken the unit to work and tried to boot it onto our 4K television, and there's no output once the OS loads.
If I plug in a 1080p monitor, then it loads fine and shows the login screen, but if I try it with a 4K display, I get "No Signal".
- You can see the motherboard POST
- You then see the initial apple logo and progress bar as it loads.
- Then the screen flashes black, and it goes to a blank screen, and the display shows "No Signal".
However, if I boot the machine with the 1080p monitor, as soon as I reach the login screen, I can connect the 4K display, and it sends a signal to the screen and mirrors the displays. I can then disconnect the 1080p screen, and macOS recognises the change and displays on the 4K screen only. If I reboot in this config, I get the same initial "No Signal" error.
Some background info: I've tried this with a 4K ASUS screen, and a 4K Toshiba TV. I'm plugging straight into the GPU with an HDMI cable (for the TV) and straight into the GPU with a DP-to-DP cable (for the ASUS monitor). [Also the GPU is in SLOT2]
Any help would be greatly appreciated.
This is the first confirmation of a 5K Thunderbolt 3 display working on this motherboard -- and out-of-the-box, no less! Thank you for posting that - it deserved its own reply.@CaseySJ
I can also give a further update, moving on from my initial post. I have plugged in an LG 5K UltraFine display into the TB3 port (after running a DP-to-DP cables from the RX580 to the DP-in) and it runs this absolutely fine, and boots to it with no issues.
This is a longshot, but worth trying...@CaseySJ
Thanks for the reply. Yes, I'm using a Sapphire X580 Pulse 8GB in slot 2.
I have tried unplugging and re-plugging both the HDMI, and the DP cables and this doesn't help. I have also tried plugging the HDMI cable into the mobo directly - this also doesn't help.
I had thought maybe it was an issue with the TV, but it also happens with the ASUS screen. Both the TV and screen have been used for a long time with genuine Mac mini's, etc with no issues.

EDIT: I haven't done the Framebuffer patch at the moment.
