Your free mini
theatre at home.

Video streaming, music streaming and screen sharing are designed for laptops and desktop PCs. Start with a current Chrome or Edge browser. On smartphones, Mic and Speaker is available in portrait mode; the other modes show a laptop-only warning.

Yes. Open Mic and Speaker on your phone in portrait mode. Choose Phone mic to broadcast your voice, or open a numbered speaker link to listen. A typical room uses one phone microphone and up to three laptop speakers. Phone microphone access needs trusted HTTPS and your permission.

No app or browser extension is needed to use the online website. Open CineWall in your browser. A video wall uses the laptops you already have, placed side by side; their screen edges stay visible. The optional local server is a separate setup for use on your own network.

Yes. The video wall, 3D audio playlists, screen sharing and Mic and Speaker features are free to use. Supporting the project is optional.

Connect your laptops to the same Wi-Fi or hotspot. Choose Stream a video on one laptop, select your video file, and open a different numbered screen link on each laptop. Place the screens side by side, wait until they are ready, and press Play on the source dashboard.

CineWall plays your selected video or audio files, and the Video and Audio dashboards include YouTube downloads. It does not integrate Netflix, Disney+, Prime Video or other subscription services. Protected video may appear black when screen sharing.

MP4 with H.264 video and AAC sound is the safest video choice. Some WebM and H.264/AAC MKV files also work. For music, try MP3, WAV or AAC. Each laptop must support the file's codecs. CineWall checks your selection and does not convert it.

Choose a mode and Create room. Copy the short Room ID from the dashboard. Your friends open the same website or local server, choose the same mode, click Join room and enter the ID. Their screen or speaker number is assigned automatically. Keep the source dashboard open for Instant sharing.

No. Choose your movie or songs on the source laptop only. It shares the selected file with the devices that join its room.

Video walls support 1–3 laptops, with 2–3 recommended for a wider picture. Audio rooms support up to 5 speakers and 10 songs. Screen sharing supports up to 10 numbered screens, plus the presenter. An optional room call supports up to 4 devices. Mic and Speaker supports one phone and up to three speaker slots.

Yes. Join the room call from the Screen sharing page, then enable your microphone or camera if you want. Up to four devices can join the call. Use headphones to reduce echo. Camera and microphone access need a secure connection and browser permission.

Open the file in its usual app, choose Screen sharing on a laptop or PC, and share that window, tab or screen. Viewers see the same view. This does not create an extended desktop or let one computer control another computer's apps.

Yes. Add up to ten songs and drag them into order. When a song ends, the next one loads and starts after every selected speaker is ready. If there is no next song, the current song plays again. Keep the source dashboard open.

Click Try in 3D in the audio player or select 3D Sound in Settings. The recording's left and right channels are spread across laptops in speaker-number order. A smooth gradient follows the stereo mix and grows where sound is louder. Volume, mute and pause affect it too. Mono recordings stay balanced; CineWall does not create Dolby Atmos.

Browsers can block sound until you interact with a page. Click Enable sound or Enable speaker once when asked, then use the source dashboard for playback and individual volume controls.

Wi-Fi, browser buffering and device speakers can add different delays. Use the same strong Wi-Fi, keep the source laptop awake and avoid Bluetooth speakers for less delay. Screen sharing Auto quality reduces traffic as more viewers join. Exact timing across every device is not guaranteed.

Instant shares a file from the source laptop; keep its dashboard open. On the online website, use the same Wi-Fi or hotspot. Upload first saves a temporary copy on the server for the other screens to play. Neither option converts the file.

Share the room ID or numbered device links only with people you want to join. Guests receive their own screen or speaker; only the creator controls the room. Keep the separate admin recovery key private. Your browser asks for permission before using your microphone, camera or screen.

The online website needs internet to load and connect your room. For local use without internet, run the CineWall server on one laptop and connect the others to the same Wi-Fi or hotspot. Phone microphone access still needs trusted HTTPS; see Mic and Speaker setup help.

Open the correct numbered link, check that every laptop is on the same Wi-Fi, and keep the source dashboard awake. Enable sound when asked and wait for each screen to report ready. If Instant cannot connect, allow local network access if prompted or try Upload. Refresh pages after a website update so every device uses the same version.
