Special Designed, Mini Micro USB on transmitter Unit

Although the price of some passive-type HDMI extenders is cheap, there are a variety of complaints about the extender sold on eCommerce websites. The most common issue is that the products can not function as advertised, which includes:

  1. Short transmission distance, even using high-quality cables.
  2. Video/ audio loss.
  3. Image distortion.
  4. Wrong instruction to cause improper installation.

Mini USB Design

The extender typically extends the signal based on the 5V power from the HDMI source device, high-quality cables, and installation environment. To remain a stable connection, the mini USB port allows you to solve the following issues:

  1. When the environment has interference, you can use the mini USB port to provide sufficient power to stabilize the connection.
  2. The mini USB port can also act as an indicator that helps installers to identify transmitters from receivers.
