Requirements and limitations for High Performance
Keep the following in mind when using High Performance screen sharing:
High Performance requires high network bandwidth (75 megabits per second for a single 4K display) and consistent low network latency.
A wired network connection is recommended.
Both Mac computers must be able to communicate with each other over UDP ports 5900, 5901, and 5902.
Only one High Performance screen sharing session can be active on each Mac at a time.
The maximum screen size supported on a virtual display is 4K (3840 x 2160 pixels or 1920 x 1080 HiDPI).
To support HDR video reference mode, you must choose the HDR Video (P3-ST 2084) preset in Displays settings. See Use the Preset menu in Displays settings.
If you authenticate using the name of the user logged in to the target Mac, the hardware displays connected to that Mac are blanked to give you privacy. This also means no one can use that Mac while you’re using High Performance screen sharing.
