7590 HDMI (or Type-C to HDMI) cannot detect external monitor (macOS 11.2.3, EFI 21.3.18) #106

Tried:

  1. Hold Option key and click Detect Displays in Display Preferences Dialog.
  2. Uncomment DeviceProperties->PciRoot(0x0)/Pci(0x1f,0x3) alc-device-id and alc-vendor-id.

And I found PciRoot(0x0)/Pci(0x2,0x0) has two commented key enable-hdmi-dividers-fix and enable-hdmi20. WG's README said:

-igfxhdmidivs boot argument (and enable-hdmi-dividers-fix property) to fix the infinite loop on establishing Intel HDMI connections with a higher pixel clock rate on SKL, KBL and CFL platforms.

My model is i7+1080P and monitor is AOC Q2490W1.

Hoping for any luck？

Add a boot argument "agdpmod=vit9696", I have solved this problem just now.I really been puzzled by this a long time.
