The answer depends on the screen mirroring method you're using.
- Wireless screen mirroring: Yes, you need Wi-Fi to screen mirror wirelessly. This is because wireless methods, like AirPlay or Miracast, rely on a wireless network to transmit the screen data.
- Wired screen mirroring: No, you don't need Wi-Fi if you're using a wired connection. This could be a HDMI cable or a USB-C to HDMI adapter.
Here's a breakdown:
Wireless Screen Mirroring:
- How it works: Your device sends a signal over the Wi-Fi network to the display device, like a TV or projector.
- Examples: Apple AirPlay, Google Chromecast, Miracast.
- Benefits: Convenience, no cables needed.
- Drawbacks: Potential for lag or interruptions, limited range.
Wired Screen Mirroring:
- How it works: The devices are directly connected through a cable, transmitting the screen data directly.
- Examples: HDMI cable, USB-C to HDMI adapter.
- Benefits: Stable connection, no lag.
- Drawbacks: Less convenient, limited mobility.
Ultimately, whether you need Wi-Fi to screen mirror depends on your chosen method and the capabilities of your devices.
