Can't control brightness of OLED display without enabling HDR

macOS Version

None

What is your CPU's model?

AMD 5800小时

Please describe the feature in detail.

I apologize for my limited English skills. Currently, the computer I'm using is equipped with an OLED display, but in the Hackintosh system, I'm unable to access its maximum brightness level or utilize the brightness adjustment function. My own technical knowledge in this area is quite limited. Regardless of whether this issue can be resolved, I sincerely look forward to your reply.

What alternatives have you tried, if any?

Currently, I'm using software to control the brightness, but I'm still unable to access the maximum brightness level of the screen.

Greetings. It seems like this is the first issue you open on this repository.

We are letting you know that these are for bug reports or feature requests. Most of the reports we receive in this GitHub Organisation are user errors.

For the sake of saving time, here are the most common cases:

• Outdated version of this kext.
• Conflicts with other kexts (e.g. WhateverGreen).
• Issues caused by other kexts like memory corruption (e.g. AirportItlwm).
• Intended behaviour by Apple (e.g. V-Sync or cursor rendering).
• Using cheap hacks like kext/library downgrades (e.g. OCLP, BFixup).
• Duplicate kexts.
• Malformed config.plist caused by configurator software (OCAT, OCC, etc).
• Lack of TSC synchronisation or use of badly programmed TSC kext (only use ForgedInvariant).
• Outdated macOS minor version (e.g. macOS 11.0.0 instead of latest).
• Using beta versions of macOS.
• Using the kext during installation or update. There is a Lilu bug which makes macOS stall during the last install phase.
• Incorrect SMBIOS. Please use iMac20,1, MacBookPro16,3, MacPro7,1 or iMacPro1,1.
• (e)DP link training failure. -NRedDPDelay will fix this as mentioned in the README. This is last resort, black screen can be caused by other factors mentioned.
• Insufficient VRAM size.

We will never support the use of configurator software, solutions like OCLP/BFixup, or using macOS beta versions.

This issue will be looked over by the respective maintainer when they can. In the meantime, look if you can resolve this yourself via checking the above.

Be patient, we are hobbyists.

enable hdr

note: this will likely cause a link training issue, causing the display backlight to rapidly flash on boot and won't get past it

Yes, I encountered the issue you mentioned after enabling HDR. Is this problem something that can be resolved?

This behaviour is likely intentional, so closing. #301 is the real issue to fix.
