- The screen is divided into 3,600 64-pixel tiles; only changed tiles are sent, with LZ4 compression.
Field notes
Setup uses two applications: Encore5K on the Mac and Encore5K Viewer on the iMac. After the computers connect, a six-digit code pairs them, and the iMac appears in macOS Displays settings. The page describes a tile-based stream that sends changed screen areas, and reports a 55 ms round trip in a test with an M4 Pro Mac mini and a 2019 iMac.
