The Mac model fits these modes. We don’t yet have a product shortlist for these connections.

  • Screen 1: 6K / 60 Hz directly from the Mac
  • Screen 2: 6K / 60 Hz directly from the Mac

Check the monitor’s exact input and supported mode. A product listed for another screen does not cover this route.
