What to Do If Wireless Screen Mirroring Has High Latency or Stuttering? 5 Practical Solutions
Experiencing screen stuttering, audio-video desynchronization, or high operational latency during wireless screen mirroring can really ruin the experience. These issues are usually not caused by hardware failures but by network or settings problems. This article shares 5 effective solutions to help you get rid of stuttering for good.
Solution 1: Check and Optimize the Wi-Fi Network
This is the most common cause of issues.
- Ensure the same network: Confirm your phone and TV are connected to the same Wi-Fi. For combined 2.4G/5G networks, connect your phone to the 5GHz band—its interference is lower and speed is faster.
- Stay close to the router: Place the screen mirroring receiver as close to the router as possible, or reduce the number of walls between them.
- Reduce network load: Pause bandwidth-heavy activities on other devices (such as large downloads or online gaming) while mirroring.
Solution 2: Restart Devices
The saying “restart fixes 90% of problems” applies to screen mirroring too. Turn off your TV and router, wait for one minute, then turn them back on. This clears temporary caches and resolves network conflicts.
Solution 3: Lower Phone Resolution
Excessively high screen resolution on some phones puts pressure on real-time encoding and decoding for wireless mirroring. Try accessing your phone’s “Developer Options,” find “Simulate Display Resolution” or a similar setting, and lower it to 1080p. This can effectively reduce latency and stuttering.
Solution 4: Use Professional Mirroring Software or Hardware
- Software solution: Install the same professional mirroring app (e.g., Lebo Cast) on both your TV and phone. It’s often more stable than the system’s built-in function.
- Hardware solution: For business scenarios, use a professional mirroring adapter. It usually has an independent Wi-Fi module that doesn’t occupy the company’s main network, offering far better stability and smoothness than software-only solutions.
Solution 5: Consider a Wired Connection
If the above methods don’t meet your demand for ultra-low latency (e.g., playing competitive mobile games), use a wired adapter like Type-C to HDMI for screen mirroring. This is the ultimate solution to latency issues.
By following these troubleshooting and optimization steps, most wireless mirroring stuttering problems can be resolved. Enjoy a smooth multi-screen interaction experience!
