Cast from your computer with Google Chrome

Check the browser and TV first

Use current Google Chrome on a Mac, Windows computer, Linux computer or Chromebook. The television needs Google Cast support, either built in or through a compatible receiver. Miracast alone, or a TV browser, is not the same feature. Put the computer and TV on the same Wi-Fi network.

Google lists these desktop platforms for its Web Sender SDK. That does not establish compatibility with every receiver model or every codec. This application’s desktop route renders a local presentation that Chrome mirrors; Chrome controls the final picture and audio sent to the TV.

Select your file and choose the TV

1. Open Cast to Your TV in a normal Chrome tab.
2. Drop a video, audio file, image or PDF into the file area, or choose a file from disk.
3. Wait for the file to become ready. If preparation reports an error, read it before retrying the same file.
4. Press Cast and select your TV from Chrome’s native chooser.
5. Use the page’s play/pause, seek, volume and mute controls. For PDFs, use the page controls.

You can connect before selecting a file, then cast the selected file on that connection. Keep the source tab open. This flow uses the website’s Cast control; you do not need to open the selected video in another player first.

Change audio, subtitles and preparation quality

The gear-shaped Settings button contains Audio and Quality. Choose an available audio track if the default language or commentary is wrong. Original preserves compatible source video packets and source dimensions where possible; 1080p and 720p request smaller preparation profiles.

Open Subtitles to choose a track, add a local subtitle file or change Text size. Preserving original subtitle styling can require a different, bounded conversion path. See the subtitle guide before enabling that option on a large film. Selecting another file replaces the current selection; changing a PDF page keeps the same screening.

Understand the picture shown on the TV

Original quality is a source-preparation choice, not a promise that Chrome mirrors every original pixel unchanged. The computer, receiver, Wi-Fi and Chrome’s mirroring encoder affect the displayed result. HDR passthrough, lossless output and 4K TV output are not guaranteed.

A film can also need audio conversion even when its video remains compressed. Google documents different media limits across Cast device models. If playback struggles, try 1080p or 720p and follow the quality and buffering checks. Reducing quality is a practical comparison, not proof that your original file was damaged.

Finish playback or investigate an empty chooser

Press Stop Casting to end the active selected file’s direct presentation. Keep the computer awake while it is playing; closing the tab, letting the computer sleep or changing networks can interrupt the stream. Your original file is not modified.

If no TV appears, first distinguish browser readiness from discovery. Allow relevant local-network permission when Chrome or the operating system asks, but do not grant unrelated permissions just because a list is empty. Use Settings → Connection checks and the TV-not-found guide. Google’s computer casting instructions also explain its native chooser.
