Mirroring your Android device to your TV using a USB cable can be a convenient way to display content on a larger screen. While many assume it should "just work," technical barriers sometimes prevent seamless connectivity. This article will guide you through various methods and troubleshooting steps to achieve a successful connection.
Understanding USB Connectivity
The USB interface on a mobile phone is typically USB Type-C or Micro-USB, while TVs mostly use USB Type-A for connecting USB flash drives or playing media files. A direct connection might face software and protocol obstacles even if the hardware is compatible.
Compatibility and Support
In rare cases, smartphones and TVs natively support video output via USB. For instance, some Android flagship models with USB-C DisplayPort Alt Mode can directly connect to TVs supporting DP input through USB-C interfaces. Older smartphones with MHL support can connect to MHL-compatible HDMI ports on TVs. However, this compatibility is not widespread, as newer TVs often lack MHL ports, and USB-C input support in TVs is uncommon.
