What you need to know
This is browser viewing, not device discovery through AirPlay, Chromecast or DLNA. A TV browser must support WebRTC and the required video playback; having a browser icon alone is not enough. Compatibility varies by model and browser, and ZeroCast does not have a tested list that guarantees every smart TV will work.
Step-by-step setup
Test the television first
Open the TV's browser and check that it can load ZeroCast. Use a short test session before the real presentation; loading the homepage alone does not prove it can play the stream.
Start sharing on the PC
Open ZeroCast on the computer, choose Start sharing my screen and select the relevant window or screen. Keep the computer awake and the casting page open.
Open the viewing link on the TV
Enter the exact viewing URL in the TV browser using its remote, keyboard or available input method. Scanning the QR code on your phone opens the phone viewer; it does not automatically send the stream to the television.
Confirm playback and finish
If the TV shows a playback button, select it. Use fullscreen if that browser supports it. Check readability and sound before presenting; stop sharing on the PC when finished.
Compatibility and troubleshooting
A blank or permanently loading TV page may indicate missing WebRTC or codec support. Try an updated supported browser if the TV offers one; otherwise use a laptop connected by HDMI or another casting method supported by your devices. Both devices need internet access for session setup. The same Wi-Fi network does not guarantee playback. Latency depends on network quality and the TV's processing power.
Privacy and session limits
A TV counts as a viewer: Free supports one viewer, 1080p and a watermark, with the sender's daily allowance. Keep the viewing link private and close the TV tab when finished. Screen audio capture depends on the PC browser and operating system; the viewer starts muted and must enable sound. If audio capture or TV playback fails, use the computer's speakers or a wired connection.
When this is useful
- ✓ Show a dashboard or spreadsheet on a larger display after a compatibility test.
- ✓ Present slides from a computer when a working TV browser is available.
- ✓ Let a remote participant view a desktop demo on their compatible television.
Browser viewing, HDMI or a casting protocol?
A browser link can work without installing a receiver app or discovering a nearby device. It requires compatible web playback and an internet connection; it is best suited to readable dashboards and demonstrations where some delay is acceptable.
HDMI connects the computer directly to the display and is often a practical choice for a dependable local presentation. AirPlay or Chromecast may be more convenient when your devices already support them. ZeroCast does not emulate those receivers or bypass protected video playback, and it is not intended for latency-sensitive gaming.
Frequently asked questions
Will it work on every smart TV?
No guarantee. The TV browser needs compatible WebRTC video support. Test the actual model before depending on it; some TV browsers can load a page but cannot play the stream.
Does the TV need to be on the same Wi-Fi as the PC?
No same-network discovery is required. Both need internet connectivity for setup, and a direct or relayed media connection must be possible. A shared network may help, but does not fix browser incompatibility.
Can I watch protected streaming video this way?
Protected content may appear black or be blocked by the operating system or browser. ZeroCast does not bypass DRM. Use the service's official TV app or a supported playback method.
Can a QR scan on my phone cast to the TV?
No. A scan opens the viewing link on the phone. The television must open the viewing URL in its own compatible browser.
