Operating Instructions
Dual Modes Streaming
The PWAY W3401 supports two primary streaming modes:
- Mirror Mode: This mode duplicates your device's screen onto the large display. What you see on your phone, tablet, or PC will be shown on the TV or projector.
Ideal for presentations, sharing photos, or watching videos directly from your device.
- Extend Mode: (Availability depends on device and application support) This mode allows you to use the large display as a secondary screen, extending your device's desktop. You can perform other activities on your phone or PC while content is displayed on the TV.
Useful for multitasking, such as browsing on your phone while a movie plays on the TV.

Important Notes and Restrictions
- HDCP Copy Protection: Due to HDCP copy protection, certain streaming applications such as Netflix, Amazon Prime Video, Hulu, Comcast TV, Xfinity, Vudu, Sky Go, and BT Sport may have restricted mirroring functionality.
- iOS 17.4 and Later (EU Regulations): Due to current EU regulations, the screen mirroring function (AirPlay) is limited on all iOS devices with iOS 17.4 or later, including iPhone and iPad.
- Power Supply: Ensure the dongle receives adequate power (5V/2A) for stable operation. Insufficient power can lead to connection issues or instability.
Troubleshooting
- No Display on TV:
- Ensure the dongle is securely plugged into the HDMI port.
- Verify the TV input source is set to the correct HDMI port.
- Check if the dongle is receiving sufficient power (5V/2A). Try a different USB power adapter or port.
- Unstable Connection or Lag:
- Ensure your device is close to the dongle to maintain a strong Wi-Fi signal.
- Minimize interference from other wireless devices.
- If possible, connect to the 5GHz Wi-Fi band for better performance.
- Restart both your source device and the dongle.
- Cannot Connect to Dongle's Wi-Fi:
- Verify the SSID and password displayed on the TV screen.
- Ensure your device's Wi-Fi is enabled.
- Try resetting the dongle (if a reset button is available, refer to the device itself).
- App Restrictions (e.g., Netflix):
- Some apps have HDCP copy protection which prevents screen mirroring. This is a limitation of the content provider, not the dongle.
- Consider using alternative methods or apps that do not have such restrictions.
