Konf uses the Mux platform to bring live streamed video into events via RTMP. You can read more about setting up a live streaming stage here.
Mux delivers an adaptive bitrate stream to all viewers, meaning that the viewer's streaming experience is not impacted by the resolution and bitrate you use for broadcasting. That said, we tend to find that a resolution of 720p delivers the best results.
More specific advice on encoder settings is available via Mux's documentation here.
