Multiple problems with mirroring mobile phone screen to old TV

Recently, 3 or 4 people have been inquiring about the wireless screen mirroring of old TVs online. I post here to summarize,

I hope it will be helpful to friends who cast screens on old TV phones.

Although AWIND’s wireless screen mirroring device can be used to wirelessly project the screen to an old TV as long as the TV has a VGA/HDMI interface, it still encounters some problems in actual use.

If your TV can plug in the network cable, connect to the Internet

The DLNA protocol is still relatively easy to use when this kind of TV is projected through the AWIND wireless wireless screen mirror. DLNA screen mirroring refers to the screen mirroring of the video APP (iqiyi, Tencent TV, Huawei Video or local video) in the mobile phone to the TV. Currently, the user’s mobile phone screen mirroring TV is also mainly used in this way.

If your TV cannot be plugged into the network cable or connected to the Internet, there will be no sound in the online video of Android phone screen mirroring

If your TV does not have the function of plugging in the network cable, it means that the DLNA protocol (streaming media push) cannot be used when the phone screen is mirroring the TV, so you can only mirror the screen. In the mirroring mirroring protocol, the Miracast used by Android phones is used for mirroring, and the online video is silent on the TV (there is local), and the screen mirroring used by Apple phones can be used.

Reminder: Some old TVs only have a VGA interface, but the VGA cable does not transmit sound, no matter what the mobile phone cast screen, there is no sound.

How to solve the problem of no sound on Android phone screen

Via Bluetooth speakers. When the mobile phone is mirroring the TV on the screen, there is no sound on the TV, but there is sound on the mobile phone. If there is a Bluetooth speaker, it is fine. The mobile phone can simultaneously project the image on the TV and transmit the sound to the Bluetooth speaker.
