From the developer:
Screen to TV for DLNA can wirelessly mirror your Mac screen and audio in UHD to DLNA equipped TV. In addition, the tool works as a web browser for direct video streaming and video-file streamer. Due to DLNA TV buffer, there is typically 1-3 seconds lag between what is shown on monitor and TV.
