Mirror a Windows PC to your TV

No download, no driver, no account. Your browser does the work: TV Mirror runs a small web page on your TV that your PC opens over Wi-Fi.

Before you start

• Use Google Chrome or Microsoft Edge on Windows 10 or 11, updated to the latest version.
• Connect the PC and the TV to the same Wi-Fi network, or plug the PC into the same router with a cable.
• Open TV Mirror on the TV. In the Windows card it shows an address such as 192.168.1.20:9443. Yours will be different.

Steps

1. In Chrome or Edge, type the address shown on the TV into the address bar exactly as shown, including :9443, and press Enter. You do not need to type https://.
2. The first time, the browser shows a privacy or certificate warning. Click Advanced and then Proceed (Chrome) or Continue (Edge). Why does this appear?
3. The TV Mirror page opens. Click Share screen.
4. In the window that opens, choose Entire screen, tick Also share system audio if you want sound, and click Share.
5. Your screen appears on the TV. To stop, click Stop sharing in the bar at the bottom of the screen or close the tab.

About the certificate warning

Browsers only allow screen sharing on secure (HTTPS) pages. A website on the internet gets its security certificate from a public authority, but your TV is a device in your own home with a private address like 192.168.x.x, which no public authority can certify. TV Mirror therefore creates its own certificate on the TV, and the browser warns you because it doesn't recognise who issued it.

The connection is still encrypted and stays inside your home network. You only need to accept the warning once per browser. If you ever see this warning for an address that is not the one shown on your TV, don't continue.

Getting the best result

• Sound: audio is sent only if you tick Also share system audio when sharing the entire screen. Sharing a single window cannot include system sound; this is a browser limit.
• Smoothness: TV Mirror uses your PC's hardware video encoder and sends up to 60 frames per second. If the picture stutters, move closer to the router, use 5 GHz Wi-Fi, or connect the PC with a cable.
• Presentations: share a single browser tab or window if you only want to show one thing and keep the rest of your screen private.
• Protected video: streaming services that use copy protection may show a black area when shared. That is the service's choice, not a TV Mirror problem.
