Recently, mobile live broadcasts have become more and more popular, and live broadcast platforms such as Huya Douyu Fanxing are all the rage. How can we project the live broadcast of the beautiful anchors on the mobile phone to the big-screen TV while watching the beautiful anchors on our mobile phones?

1. Smart TV solution with WIFI
1. Turn on the TV, find [Miracast] under the corresponding column, and then turn on the [WiFi Display] function.

2. Turn on the mobile phone wifi, search for the wifi signal sent by the TV, and after the connection is established, the screen on the mobile phone can be projected to the TV.

This is the easiest way to connect your phone to a smart TV in the same wifi environment. Apple’s AirPlay operates similarly to Android’s multi-screen interactive feature.
2. Non-smart TV solutions
If it is an ordinary LCD TV, you need a Greenlink USB video converter to achieve it.

One side of the USB to HDMI/VGA converter is connected to the VGA and HDMI ports of the TV and projector, and the other side is the 3.5mm audio port, mobile phone input port, and power supply port.
