Troubleshooting: Lag, No Sound, Connection Drops

Even after proper connection, problems may arise. Let's look at the most common ones and how to fix them:

1. Image delay (lags)

• 🎯 Cause: Low frame rate (30 Hz instead of 60 Hz) or a weak adapter chipset.
• 🛠️ Solution:
  1. Reduce the resolution to 720p in the adapter settings.
  2. Connect the adapter to USB 3.0 (blue port) for stable power supply.
  3. Use the router in mode 5 GHz (if the adapter supports it).

2. No sound

• 🎯 Cause: The wrong audio output is selected on your phone or PC.
• 🛠️ Solution:
  1. On Android: open the notification panel → tap the icon Miracast → select Transmit sound.
  2. On Windows: Right-click on the sound icon → Open sound settings → Select output device (adapter name).
  3. Check if the adapter supports audio transmission (some budget models only support video).

3. The connection is broken

• 🎯 Cause: Interference from other Wi-Fi networks or weak signal.
• 🛠️ Solution:
  1. Move the adapter and router away from microwaves and cordless phones.
  2. Change the Wi-Fi channel in your router settings (optimally - 6 or 11 For 2.4 GHz).
  3. Update the adapter firmware (instructions are usually on the manufacturer's website).

4. The image is flickering or blurry

• 🎯 Cause: Resolution or screen refresh rate mismatch.
• 🛠️ Solution:
  1. Set the resolution in the adapter settings 1920×1080@60 Hz (if supported).
  2. Disable HDR in your TV settings (some adapters do not support this format).
  3. Check your HDMI cable - it must support it High Speed (version 1.4 or higher).
Why isn't Miracast working on my iPhone?

Apple blocks native support Miracast V iOS due to security policy and promotion of its own standard AirPlayHowever, there are workarounds:

1. Use adapters with support AirPlay (For example, AnyCast M2 Plus).

2. Install broadcast applications (ApowerMirror, LetsView), but they add a delay of ~100 ms.

3. Connect via Lightning to HDMI adapter (wired method, no lags).

If the problem persists, check:

• 🔌 Adapter compatibility with your TV model (on some LG OLED 2020+ firmware with support is required HDCP 2.2).
• 📡 Interference from neighboring Wi-Fi networks (use apps like WiFi Analyzer for ether analysis).
