Usually disabling those functions in the monitor settings will allow Lunar control brightness.īelow are some settings that are known to block DDC, grouped by monitor vendor. In most cases, DDC is blocked by a monitor setting that tries to take complete control of Brightness, Contrast or Volume.

: USB-C to DisplayPort Cable 3M/10Ft /144Hz/120Hz.

If possible, try a DisplayPort to USB-C cable. Some users report that DDC controls are blocked on specific monitors when using HDMI to USB-C cables and that switching to DisplayPort fixes their problem. There are other WriteI2C methods specifically for this chip inside the DCPAVFamilyProxy.kext but they're not available to be used inside an app like Lunar. That chip supports DDC, but the method we use to write the DDC commands to the monitor ( IOAVServiceWriteI2C) fails when used through it. These HDMI ports use an internal MCDP29xx chip to convert the HDMI signal to DisplayPort. Using one of the Thunderbolt ports usually fixes this (through USB-C-to-HDMI cable, Thunderbolt hub, etc.). The HDMI port of these devices is blocking DDC requests without a known cause.

Some monitors don't accept DDC commands (which Lunar uses to control brightness and volume).īelow are some possible causes for this issue.īuilt-in HDMI port of the newer Mac devices

Can't change the volume or input of the monitorīrightness controls are locked after standby/wake.

That's why you have to manually set the monitor brightness and contrast to maximum using its physical buttons.

Can only lower the brightness, not increase it.

Night Shift is a good alternative as it doesn't use Gamma.

Conflicts with other apps that use Gamma like f.lux so you have to quit them.

Lunar will fallback to adjusting brightness and contrast in software using Gamma values. To do that, disable Hardware (DDC) controls from the Controls menu: If the problem persists, you will need to disable DDC completely. You can try to open Advanced Settings and enable the Delay DDC after wake experimental setting: Some monitors have firmware bugs and don't react well to DDC commands. The flash you see comes from Lunar detecting this zero-gamma problem in the background, and applying a default Gamma table forcefully to avoid being stuck with a blacked out display. This should be a completely normal use case, and the call should simply do nothing if the gamma tables are already at their default values.īut for unknown reasons, this API call will sometimes set all RGB Gamma tables to 0 and all colors will show up as black.

The bug is usually triggered when Lunar tries to reset the gamma tables to their default values by calling the CGDisplayRestoreColorSyncSettings() system method. This usually happens when custom color profiles are used, but it was reported on some default monitor profiles as well. If that doesn't fix the issue, you can try to disable the usage of Gamma completely from Advanced Settings

Minimise future Gamma resets by disabling the HDR compatibility workaround from HDR Settings.

Use a default color profile in System Preferences -> Displays.

There's no complete fix for this as it is a macOS bug, but you can lower the chances of it appearing using the following steps: Unplug the monitor from the power socketīecause of a macOS bug in the Gamma API, your screen can go black then get back to normal after a few seconds.
