If the encoder produces data faster than the host can upload it, packets wait in network and playback buffers. Each late frame then arrives behind another late frame. Automatic Lite mode watches the symptoms of that queue and reduces the stream before it grows indefinitely.

Lite preserves the entire screen shape but caps the vertical output at 720 pixels and gives video a strict 1.55 Mbps budget. That trade keeps motion current on a 2 Mbps connection. Full mode is the right choice when sharp 1080p or 1440p text matters and the link has enough headroom.

No. An automatic switch is temporary. The host remembers the Full profile in memory and restores it when the connection remains healthy. Manual 2 Mbps Mode is still saved normally.

Both downloads install the same current host components. Download Lite launches them with the low-speed profile locked on every run; Download Hosting starts with your normal settings and falls back only when receiver telemetry stays poor.

Yes. The host captures system output rather than the microphone. Lite compresses it as 48 kHz stereo Opus at 40 kbps; the browser uses the native audio track when available and a separate fallback channel otherwise.

Check that the host really has 2 Mbps of upload, not only download. Pause cloud backups, game updates and video calls; move closer to the access point; avoid a VPN; and compare with Ethernet. Packet loss and Wi-Fi retransmissions can make a nominal 2 Mbps test behave far below 2 Mbps.
