Dummy mirroring method for HiDPI scaling (native smooth scaling not affected) - Only SDR content is supported #141

Closed waydabber closed 2 years ago

waydabber commented 2 years ago

Issue description

Dummies do not support HDR content.

Root cause

This is an inherent limitation of the macOS CGVirtualDisplay API used by the app therefore cannot be fixed at this time.

Resolution

The situation might change once Apple introduces HDR for AirPlay or SideCar.

waydabber commented 2 years ago

If you have this issue and are using the app only to mirror a dummy screen to a real display on Apple Silicon in order to have flexible HiDPI resolutions, please check out the latest beta which includes a new smooth scaling feature for native displays (no dummy required).

The feature requires macOS Monterey 12.4, 12.5 beta or Ventura and requires a Pro license.

Thank you!
