A SignalDeck product · Private testing
Your phone runs the room. The display does the presenting.
RelayDeck turns your Android phone into a focused, responsive controller while the room sees only the content. Every action stays requested until the receiver confirms what is actually on screen.

The private-test build, on screen
Requested here. Confirmed there.
These are the running Android controller and tokenless receiver shell—not concept art. The controller keeps a requested change visibly pending until the receiver acknowledges the state it actually applied.
No guesswork between screens
Control that closes the loop.
RelayDeck separates what you asked for from what the display has proven it applied.
Connect the room
Pick the Cast display. A short-lived join code starts a private receiver session without exposing content credentials.
Present with proof
Navigate, jump, zoom, scroll, rotate, fit, or blank. RelayDeck marks each action confirmed only after the receiver visibly applies it.
One controller, four content paths
Prepared for the room.
Documents are converted into display-ready pages before presenting, so the receiver remains quiet, predictable, and free of editing chrome.
PowerPoint
Slides, thumbnails, text, and presenter notes prepared for reliable navigation.
Sharp page rendering with fit, zoom, rotate, and continuous movement.
Word
DOCX documents become ordered, presentation-ready pages.
Images
JPEG, PNG, and WebP images are orientation-corrected and prepared as crisp full-display assets.
Video
Accepted video is normalized for dependable Cast playback, fast first frame, seeking, and absolute TV confirmation.
Audio
Audio becomes a consistent AAC presentation stream with a waveform, transport controls, and captions when available.
Public webpages
Compatible HTTPS pages can be framed, refreshed, zoomed, and scrolled.
Built for trustworthy private testing
The room gets the presentation. You keep the controls.
