Two source types that need no extra hardware:

• GUI — captures one of your monitors, with an optional floating webcam overlay for talent. Use it to stream a live edit-bay or desktop.
• GEN — a self-contained test-card / clock generator for line-up, signal-path checks, and HDR verification.

How to open it

1. Click Add Row, then under Select Source Type choose GUI or GEN.
2. Click the row's gear button to open its settings.

A GUI row also has two inline buttons: SCREEN (live screen on/off) and CAMERA (webcam overlay on/off).

Part 1 — GUI: Screen Capture & Webcam Overlay

A GUI row captures one monitor and streams it. You can float a circular webcam window on top of that monitor so the capture picks it up.

macOS permissions (read this first)

• Screen Recording — needed for capture. If it isn't granted, Pulsar points you to System Settings → Privacy & Security → Screen Recording; enable it and restart Pulsar.
• Camera — needed only for a webcam overlay. Approve the prompt, or enable it later under System Settings → Privacy & Security → Camera.

Stream one of your monitors

1. Add a GUI row. On macOS, grant Screen Recording if prompted (and restart if asked).
2. Open the row's settings.
3. Under Monitor to share, pick your display (or leave Auto (Primary)). Click Refresh Monitors if a just-connected display is missing.
4. Set Aspect Ratio to Fit (keeps shape, adds black bars) or Stretch to 16:9 (fills frame, may distort).
5. Click Apply.
6. Make sure the row's SCREEN button is green, then configure outputs and start the stream.
