Problem: I can't connect to the receiver.
First Steps:
  • Confirm both your device and the receiver are on the same Wi-Fi network.
  • Try connecting via IP address to rule out network discovery issues.
  • Restart the EShare app and check if the receiver appears.

Advanced: Your network firewall may be blocking required ports. Please contact your IT administrator for assistance.

Problem: There is no audio during mirroring.
  • Universal: Check that volume is not muted on your source device, the EShare app, or the main display.
  • For Windows: In the EShare app settings, ensure the "EShare Audio" Virtual Audio Card is enabled.
  • For Android 10+: System-wide audio is captured. On older versions, audio will play from your phone.
Problem: Black screen during screen mirroring.

For Windows users, try switching encoding mode in Settings > Encoding Mode, change from "Hardware" to "Software" to resolve compatibility issues with certain devices.

Problem: Miracast (Win+K) is not working.
  • Ensure Miracast is enabled in ESharePro settings.
  • Click the "i" button next to the Miracast option in settings, enable compatibility mode and try again.

Troubleshooting (Continued)

Problem: Mirroring is laggy or choppy.

A flawless streaming experience depends on a high-quality network connection. Video is particularly sensitive to network performance.

Network Best Practices:
  • Wired Receiver: For maximum stability, connect the EShare Receiver to the network with an Ethernet cable.
  • 5GHz Wi-Fi: Ensure client devices are connected to a stable 5GHz Wi-Fi band, which is less prone to interference than 2.4GHz.
Performance Targets for Demanding Use Cases:
Bandwidth
30 Mbps
Stable bandwidth per video stream.
Latency
< 50ms
Low ping time between devices.
Jitter
Near Zero
Minimal latency fluctuation.
