HackAlexS Posted January 22, 2020 Share Posted January 22, 2020 (edited) Hello I have an Gigabyte Designare Z390 motherboard and latest BIOS running Catalina 10.15.2. I have an NVidea Geforce 1070 graphics card which I am not using, that's hopefully disabled. Motherboard comes with an Intel UHD 630 internal display adapter which I have spent days trying to get working at UHD resolution. I've finally managed to get UHD via HDMI (I had another thread here and fixed it myself). The only issue now is that it's only running at 30Hz, not at 60Hz. The monitor will only work at HDMI 1.4 not HDMI 2.0. I know it will work because Windows 10 has no problem at all with the Intel UHD630 under HDMI 2. Can somebody tell me please what to do here? I've tried many boot flags and tried to change config.plist. Also config.plist does have from hackintool this entry but it's not working: enable-hdmi20 I attach clover folder (zip) and a text file listing the kext files I have in /Library/Extensions, and pasted below a report on my display. If you need any further info please ask. Many thanks...! ---> Intel UHD Graphics 630 (Desktop 9 Series): Chipset Model: Intel UHD Graphics 630 (Desktop 9 Series) Type: GPU Bus: Built-In Slot: Internal@0,2,0 VRAM (Dynamic, Max): 1536 MB Vendor: Intel Device ID: 0x3e9b Revision ID: 0x0002 Metal: Supported, feature set macOS GPUFamily2 v1 Displays: U32R59x: Resolution: 5120x2880 (5K/UHD+ - Ultra High Definition Plus) UI Looks like: 2560 x 1440 @ 30 Hz Framebuffer Depth: 30-Bit Colour (ARGB2101010) Display Serial Number: HTOM500757 Main Display: Yes Mirror: Off Online: Yes Rotation: Supported Automatically Adjust Brightness: No ------------- Display: Type: GPU Bus: PCIe Slot: Slot-1 PCIe Lane Width: x16 Vendor: NVIDIA (0x10de) Device ID: 0x1b81 Revision ID: 0x00a1 Kernel Extension Info: No Kext Loaded Clover.zip Extensions.txt Edited January 22, 2020 by Guest Quote Link to comment Share on other sites More sharing options...
HackAlexS Posted January 22, 2020 Author Share Posted January 22, 2020 Nevermind, I'm wrong. Limitation of motherboard and internal graphics. It's 30Hz. I have another question, do you own a Z390 Designare Motherboard with a working/clean Catalina install? I'm keen to compare notes and want to clean up my system. Would you mind posting your clover folder and a list of kexts in /library/extension. You can create the list in extensions by dropping to terminal and typing: ls -l /Library/Extensions > files.txt and then attach it here. If anybody has any tips as well please let me know... Thx.
