Hi Maldon, I have this computer but I can't get the HDMI output to work, but the DisplayPort output does work. The thing is that the HDMI seems to receive a video signal but the screen is black. I tried changing cables. I tried different 4k and normal monitors, I also used both HDMI and DisplayPort outputs at the same time and tried to configure the screen settings since both screens are connected but the HDMI always gives black video.

I'm sending you your EFI for Big Sur. But I'm in Sonoma now and I tried to update to OC but this doesn't work.
