Micro USB to HDMI Adapter Converter Cable For HD TV Android Phone Description: Product test method: - The lines that make up the connection include: the same screen device, 1.4 standard HDMI signal transmission line (A-type male to A-type male), mobile phone data line + charging head. First connect the Micro USB connector of the same screen device to the data interface of the mobile phone, and then connect the HDMI cable to the HDMI-A Female interface to form a basic HDMI signal transmission line. It is worth noting that the same screen device can only work through a borrowed power supply, so dont forget to plug the original data cable of the phone into the Micro USB Female port on the side of the adapter, and then turn on the power. Connect with HDTV After the playback terminal is assembled, transfer to the high-definition display terminal. The high-definition display terminal we tested is a SamsungLA40C530 40-inch full HD LCD TV (16:9 widescreen, with HDMI and USB ports, and full support for 1080P HD). Mobile phone screen and HD TV image synchronization When the mobile phone and high-definition TV are turned on normally, and the HDMI icon is displayed on the screen of the mobile phone or the TV screen, it means that the HDMI signal of the mobile phone is normally transmitted to the high-definition TV through the same screen device.
