Displaying HDR Content in Photomator and Pixelmator Pro

Supported Displays

Full XDR displays. For the most striking results with HDR photos, use the latest Apple devices with full XDR displays. This includes iPhone 15 and iPhone 15 Pro, Macs and iPads with XDR displays, and Pro Display XDR. HDR content will be loaded automatically on these displays.
Limited support HDR displays. MacBook Air, iMac, iMac Pro, Studio Display, and older MacBook Pro models not equipped with XDR displays provide limited HDR support with peak brightness ranging between 300 and 600 nits. When working on such displays, you can select whether you want to load the HDR data or not in Photomator or Pixelmator Pro settings.
Non-Apple HDR Displays. These displays are supported but offer a slightly less streamlined editing experience. For example, when editing images in HDR, the entire screen, including the app interface, will be displayed in HDR instead of just the photo itself. Additionally, after syncing edits to Photos, only SDR versions of photos will be available in the Photos library.
