I have Macbook M1 Air with 8GB and 256SSD attached to a BenQ SW271 in HDR mode. MacOS recognizes and activates the monitor correctly as a HDR display, but Photoshop (current 2022 version) shows the 30bit display option greyed out. Is Photoshop able to support the full color spectrum of my SW271 on the M1 Macbook? How?

The following things need to be set in order to view HDR on Mac: 1. In System Prefs > Displays choose a Preset that supports HDR (P3-500 or greater, I'm using P3-1600) 2. In Photoshop go to Preferences > Technology Previews > and enable Precise color management for HDR display 3. Quit and re-launch Photoshop and should be able to see HDR images displayed correctly to screen

Use SwitchResX to test and see if the monitor that's connected is displaying billions of colors mode i.e. outputting a 10-bit signal. That's probably the issue.  Check to see which of the cables used supports the highest bit depth and make sure that is what your using.  Hopefully that helps!

Hi Bob, thanks for your advice. Fortunately, the cable is not an issue and SwitchResX shows a billion colors. Unfortunately, Photoshop does not. Any idea where to look?
