NDI Monitor is a professional application developed by Mark Gilbert, a global IP Video leader. This app allows users to easily monitor NDI sources on their local subnet. With a simple tap on the screen, a pop-up menu presents all available NDI sources for selection. Additionally, users can enter additional 'NDI Access' IP Addresses from other subnets in the system preferences panel to access more NDI sources.

NDI Monitor offers several useful features, including support for NDI Discovery server, resolution control, video flip for autocue, and control of NDI network Protocol for reliability. It is important to note that a stable WiFi connection or a wired ethernet connection is required for smooth playback of NDI streams. Users experiencing glitching of audio or dropped video frames are advised to try a wired ethernet to lightning adaptor for improved stability.

The app also provides customization options through the System Settings app, allowing users to set up application preferences. Additionally, the NDI Scanner app can be used as a stream selector, opening NDI Monitor when a selected stream is clicked. For users with multiple devices on the same network, setting the "NDI Device Name" in the app settings is necessary to give them unique names.

Please note that NDI Monitor does not support NDI | HX1 format streams, only full NDI format and NDI HX2.
