Guest 5T33Z0 Posted September 2, 2020 Share Posted September 2, 2020 Hi, I recently upgraded my Hackintosh Built to a Gigabyte Z490 Vision G with an i9 10850K CPU. Everything is working fine so far using OpenCore. But I am having issues with the HDMI and DisplayPort of the iGPU. I tried several patches using Hackintool to get either HDMI to DVI Cable or DisplayPort to DVI cable to work, but every time I boot, the Monitor turns off. I don't know how to fix it. Can somebody point me in the right direction? Thanks. EFI_Z490_VisionG_0.6.1_nightly.zip HDMI Patch.plist Link to comment Share on other sites More sharing options...
deeveedee Posted September 9, 2020 Share Posted September 9, 2020 (edited) Take a look at my HP EliteDesk 800 G4 Mini thread where I patched UHD 630 for DP->DVI cable. From what I have observed, the keys to success with UHD 630 when using adapters (e.g. DP->HDMI or DP->DVI) are as follows: Read and refer to these references Choose connector BusIDs based on the converted type and not on the connector type on your motherboard (e.g. if you are using a DP->HDMI adapter, select a valid BusID for HDMI) Choose the connector type based on the converted type and not on the connector type on your motherboard (e.g. if you are using a DP->DVI adapter, select connector type DVI and not DP) To avoid an AppleALC kernel panic on wake from sleep, you may need to add HDA property no-hda-gfx as I have described in my thread If using multiple displays, add boot-arg igfxagdc=0 Enable remote access to your hack so that you can "Remote Desktop" into your system when it boots to black screen. I have tried to make my HP EliteDesk thread a guide specifically for the HP EliteDesk 800 G4 Mini and a general educational reference, so I would suggest reading the following posts in my thread: Post #1 Known Issues My installation methodology Framebuffer patching Edited September 9, 2020 by tonyx86 Link to comment Share on other sites More sharing options...
