A little help for the big screen

to watching.
Work out whether the problem is connection, preparation or playback. These checks explain what the website can verify and what your device controls.
Open the playerWhen Chrome cannot find your TV
An empty Cast chooser can mean a discovery problem, not an unsupported file. Read connection checks, compare receivers, and use Android’s system fallback.
TroubleshootingFind where the sound stops
Work through muted playback, wrong audio tracks, MKV sound formats and phone mirroring limits. Keep discovery problems separate from missing TV audio.
TroubleshootingImprove a soft picture or interrupted playback
Understand Original, 1080p and 720p preparation, then check source decoding, local Wi-Fi and mirroring limits when TV playback looks soft or buffers.
TroubleshootingCasting has sound, but the TV picture is black
Fix casting with sound but no picture by separating file decoding, receiver output and protected-content restrictions. Check images, video and device routes.
TroubleshootingWhy casting stops when your phone locks
Understand why browser casting can stop when a phone locks, Safari closes or a computer sleeps. Check Android projection, AirPlay and playback policy separately.
