Interface Overview

From this page, you can:

  • Mirror one or many devices simultaneously

  • Interact live using tap, swipe, scroll, or type actions

  • Adjust frame rate (FPS) and bitrate (Mbps) for performance or clarity

  • Manage individual or grouped mirrors with quick start/stop controls

Mirror Modes

  • Single Mode: View and control one device at a time

  • Multi Mode: Mirror and interact with multiple devices simultaneously (performance depends on your GPU specs)

Settings Controls

Fine-tune your stream for quality or performance:

  • Frame Rate (FPS): Adjust smoothness (default 15 FPS)

  • Video Bitrate (Mbps): Adjust video clarity (default 1.0 Mbps)

Restart mirrors to apply changes.

Mirroring View

During an active mirroring session, each device is mirrored in real time, you can:

  • Interact with the screen (tap, swipe, pinch, type)

  • Resize or rearrange mirrored windows
