The use of wireless connection must first ensure that the TV is a smart TV, in addition, the phone and the TV need to remain in the same WiFi network state, Apple and Android devices are slightly different.
1. Swipe up from the bottom of the screen of the Apple device to open the \"Control interface\
2. Android devices take Xiaomi mobile phone as an example, first open the \"wireless screen projection\" or Miracast similar application on the TV, and then open the \"wireless display\" in the wireless connection mode of the phone, then the name of the TV will appear on the phone, and the phone can be displayed with the TV on the same screen after the connection is successful. The cable connection needs to use the HDMI or VGA interface of the TV, of which the HDMI interface needs to have the MHL function, which refers to the Mobile terminal HD video and audio standard interface (Mobile High-Definition Link), generally there will be this sign on the interface. In addition, mobile phones also need to support MHL function, but it seems that there are fewer and fewer mobile phones that support MHL recently. 1, Apple devices Apple devices need to use Lightning digital audio converter or Lightning to VGA converter, the official price is 388 yuan, and then use an HDMI\/VGA cable can be connected to the TV. 2, Android devices Android phones need a dedicated MHL line, which is cheaper than the above Lightning converter, and the connection methods are similar, but say more. In fact, the most economical and convenient way is wireless connection, but if it is a relatively long non-smart TV, you can only choose the plug and play wired connection, but in this case I recommend that you use the TV box, the price is even cheaper than those transfer cables, and wireless multi-screen interaction is much more convenient. s
