AUXDECK DOCS

Set up once. Keep it local.

Install the desktop app, pair your phone, then choose what the phone should become.

Quick start

  1. Install AuxDeck Desktop on your computer.
  2. Open AuxDeck on your phone.
  3. Tap Scan and point the phone at the desktop QR code.
  4. Keep both devices on the same local network.

The QR code in Desktop Settings stays available so another phone can pair or this phone can switch computers.

Windows

  1. Run the x64 installer and approve the administrator prompt.
  2. Allow AuxDeck on private networks.
  3. Leave AuxDeck running in the system tray.

The package includes the Windows agent and virtual camera. If camera registration fails on a normal Windows installation, setup reports an error instead of hiding it.

macOS

  1. Move AuxDeck Desktop to Applications.
  2. Allow Accessibility for keyboard and pointer control.
  3. Allow Screen Recording when using the temporary display.

AuxDeck checks permissions quietly. It opens System Settings only when you choose to grant a missing permission.

Phone setup

  • Home and Settings stay in portrait for a consistent layout.
  • Work screens can follow the device or stay locked to portrait or landscape.
  • Use Switch computer in Settings to scan a different desktop.
  • English, Chinese, French, and Spanish are available on this website. Mobile language support is being expanded carefully.

Computer status

The default frame-rate widget shows the active display refresh rate during normal desktop use. When a full-screen app is active and PresentMon has valid frames, it shows that app's measured FPS.

Screen rate
Display refresh rate, or full-screen app FPS when available.
App FPS
A separate optional component for the foreground application.
Unavailable
Shown when a real source cannot be measured. AuxDeck does not invent a value.

Controls and macros

Build pages from media, system, OBS, Codex, touch, and phone tools. Use macros only when an action needs multiple steps, timing, conditions, or repetition.

  • Editing an official page creates a user copy.
  • Names you enter are preserved and never translated automatically.
  • Approved scripts and local plug-ins stay under desktop control.

Studio

Camera and microphone start as one session. Add the teleprompter when needed, or open Program return and tally for an OBS workflow.

  1. Choose Camera & microphone in Studio.
  2. Select AuxDeck Camera or Microphone in OBS, Zoom, or another desktop app.
  3. Keep AuxDeck in the foreground while sending media.

Temporary display

The computer picture keeps a 16:9 area. Touch controls and named keys sit beside it instead of covering the image. Screen Recording permission is required on macOS.

Troubleshooting

Phone cannot connect
Confirm both devices use the same network, reopen the desktop QR code, and pair again.
Android will not install
Allow Install via USB or approve the system package installer. Xiaomi devices may require one manual confirmation.
Camera is missing
Restart the desktop app after installing the virtual device, then reopen OBS or Zoom.
Frame rate looks wrong
Check whether the widget is Screen rate or App FPS. They measure different things.

Privacy

Pairing credentials stay in operating-system secure storage. Control traffic remains on the local network. Camera, microphone, screen, and accessibility access are used only for features you start or configure.
