@pastrychef I think I have found the reason why macOS cannot detect the HDMI signal after booting. ResXtreme shows that all options are duplicated, only for HDMI.

If I double-click on the other but same option, the image will remain the same but I will not need to replug the HDMI cable anymore. If I choose the original option back later, the signal will immediately stop.
@pastrychef I am glad to say that I resolved the DisplayPort colour banding issue and confirmed the results by observing the interface in Dark Mode carefully, including sidebars and Launchpad. After multiple restarts, colour banding still no longer happens.
The steps are incredibly simple without any technical skill.
If the results remain fine after one week, I will mark this topic as Solved.
- Open Hackintool
- (If it is on macOS Catalina or later, switch to the Tools tab and press Disable Gatekeeper and mount the disk in read/write mode)
- Switch to the Display tab and just export without changing anything
- As Hackintool has generated 3 files and 1 folder to Desktop, just drag the folder DisplayVendorID-xxxx to /System/Library/Displays/Contents/Resources/Overrides
