Can I switch HDR and image adjustments together with a Shortcut?

Yes. Create a macOS Shortcut that sets the display's HDR state and then applies your chosen image adjustments. Use explicit On or Off values so running it twice produces the same intended state.

For example, make an HDR viewing Shortcut with BetterDisplay actions in this order:

1. Toggle HDR Mode: choose the target display and On.
2. Toggle Image Adjustments: choose the same display and On to use its configured adjustments.
3. Add Image Adjustment actions for the individual values you want to set. Select the feature and value in each action. The feature must be supported by that display's configured controller.

Make a second SDR viewing Shortcut that sets Toggle HDR Mode to Off and Toggle Image Adjustments to Off, or applies a different set of values if you want adjustments in SDR too. Test both Shortcuts with the display connected and check the resulting HDR state and image.

Toggle Image Adjustments suspends or resumes the display's configured color effects without resetting their stored values. Software brightness remains effective, so choosing Off does not turn off software dimming or upscaling. It does not change the global Allow color table control setting or select a different adjustment method. Use the appropriate Image Adjustment action for a hardware setting you also want to change. Suspending color effects does not reset hardware brightness or contrast.

A Shortcut groups commands that run when you invoke it. It does not automatically watch for HDR changes made elsewhere, nor does it add image-adjustment values to Configuration Protection. Use these Shortcuts as your SDR/HDR switching entry points if you want the choices applied together. Available HDR modes and adjustment methods still depend on the display and connection.

See BetterDisplay actions in Shortcuts for action parameters, and Configuration Protection for the settings that BetterDisplay can enforce automatically.
