HDR support / "SDR Brightness" in HDR

Twinkle Tray does not currently support HDR. Most monitors do not support HDR brightness control over DDC/CI, but modifying "contrast" may work as an alternative. Windows offers an "SDR Brightness" setting, but there's no official API for this. Twinkle Tray may support an unofficial "SDR Brightness" API in the future.

Brightness keys

3rd party app cannot detect "brightness" keys on most keyboards. "Brightness" keys are typically handled at the driver level and do not get broadcast to the rest of Windows. If your keyboard supports rebinding the "brightness" keys to a key combination, you can set up that key combination as a hotkey in Twinkle Tray.

Lowering brightness below 0% / Black screen filter

To lower screen brightness below hardware limits, some 3rd party apps place a transparent black layer above all windows. There are no plans to implement a feature like this into Twinkle Tray. If you'd like to lower the perceived brightness lower than "0%", lowering the contrast or R/G/B values of your monitor will have a similar effect.

Windows "Night light" integration

Twinkle Tray does not integrate with the Windows "Night light" feature. There are no official APIs for this and any unofficial ones frequently break between Windows versions. Additionally, this feature is outside of the scope of what Twinkle Tray is meant for.

Integrating with the Windows Quick Settings flyout

There are no official APIs for this. Twinkle Tray, nor any other 3rd party application can add/remove/modify the Quick Settings flyout.

Can't turn on monitor after using power state features in Twinkle Tray

Using DDC/CI to turn off your monitor is supported in Twinkle Tray. However, Twinkle Tray cannot validate the stability of this feature. You are using it at your own risk. If your monitor doesn't turn back on, try unplugging it from the wall and plugging it back in. You may also need to look in your owners manual for instructions on factory resetting the monitor.

Can't turn on monitor from Twinkle Tray

Twinkle Tray can send the "power state" DDC/CI signal values of "4" or "5". "5" will turn off your display as if you hit the physical power button. The only value meant to be turned back on from without manually hitting the power button is "4". However, "4" is more likely to cause problems. And even if you use "4", your monitor may still need the power button pressed to wake up. Use either of these values at your own risk.
