What you need to know
Use a computer as the sender. Chrome or Edge on a desktop is a practical starting point; Firefox and Safari have capture options that vary by platform. A phone can scan the room QR code to watch, but iOS and Android browsers cannot send their entire device screen through this workflow. Scanning on a phone does not cast to a nearby TV: the TV must open the link itself.
Set up browser casting in three steps
Prepare the sending computer
Open the document, slides or application you want to show. Visit ZeroCast over HTTPS in a desktop browser. Close private notifications and choose a single window when the viewer does not need the whole desktop.
Start and approve screen capture
Choose Start sharing my screen and select a screen, window or tab in the browser's permission picker. Keep the sharing page open and the computer awake. Sound capture options depend on the browser and operating system.
Connect the receiving screen
Send the viewing link to the other computer or let a phone scan the QR code. On a TV, enter that same link in its own browser. Select Play if prompted and check the image and sound; stop sharing on the computer when finished.
Compatibility and troubleshooting
Desktop viewers need a modern browser with WebRTC playback. Phones and tablets are viewers, not full-device screen senders. A TV needs compatible WebRTC and video decoding; loading the website alone is insufficient. Test a short session on the actual TV. If its browser cannot play the stream, connect a laptop with HDMI or use a casting method supported by the TV. Both devices need internet access for setup; being on the same Wi-Fi does not fix an unsupported browser.
Privacy and session limits
The browser requires your active capture approval. Media is encrypted end to end, with direct WebRTC delivery when possible and an encrypted relay when needed. ZeroCast does not store the screen video. Keep links private: an authorized viewer can still take screenshots or record. Free supports one viewer, a watermark and 1080p, with 15 daily sending minutes for guests or 40 for registered Free users; guest time still counts after sign-in.
When this is useful
- ✓ Show slides or a spreadsheet to a colleague on another computer.
- ✓ Let a customer watch a desktop demonstration on a phone by scanning a QR code.
- ✓ Display a dashboard on a TV only after its browser passes a real playback test.
Browser links, AirPlay, Lebo and installed casting software
A ZeroCast link is opened in the receiver's browser and does not discover an AirPlay, Chromecast or DLNA receiver. AirPlay suits devices and receivers that already support that ecosystem. Lebo and other casting apps can offer device-specific sender or TV receiver workflows; their installation, network and account requirements depend on the actual product and device.
Choose the method that fits the hardware. A browser link is useful for a desktop demo without a receiver app, including remote viewers. If you need to mirror an entire phone, discover a TV automatically or play protected video, use a supported native method instead. For a nearby presentation where stability matters, HDMI avoids dependence on a TV's browser and network; ZeroCast does not bypass DRM or offer remote desktop control.
Frequently asked questions
Which browser can cast a screen?
Desktop Chrome and Edge support browser screen capture; Firefox and Safari also have platform-dependent capture options. A viewer needs compatible WebRTC playback. Check the actual browser and its screen-recording permission; mobile browsing does not imply mobile screen capture.
Can I cast my phone screen through this website?
Not through this browser workflow. Use a computer to send the screen. A phone can open a viewing link or scan a QR code to watch a computer's screen.
Are screen casting websites safe?
Use HTTPS, approve only the intended window and keep the room link private. ZeroCast encrypts media end to end and does not store screen video, but viewers can capture what they see. Stop sharing before entering passwords or payment details.
Can browser casting work on a television?
Only if the TV browser can play the required WebRTC video. Open the link on the TV and test before presenting. ZeroCast has no guaranteed compatibility list for TV models and does not turn a phone QR scan into a TV cast.
Do the sender and viewer need the same Wi-Fi?
No device discovery on a shared Wi-Fi is required. Both need internet connectivity for setup and a working direct or relayed media connection. Corporate restrictions can still block capture or playback.
