The most important information comes from the product manual of the mobile phone, or ask the manufacturer of the mobile phone.

In addition, you can go to http://www.mhlconsortium.org/ MHL official website's list → browse the product list → mobile phone, but the information inside is more accommodating.

Mobile HD Link (MHL) standard interface for high-definition audio and video of mobile terminals is a standard interface for connecting portable consumer electronic devices. MHL can be presented on HDTV through standard HDMI input interface, using only one signal line. It uses the existing Micro USB interface, whether it is a mobile phone, a digital camera, a digital video camera or a portable multimedia player, it can directly transmit the complete media content to the TV without destroying the high-resolution effect of the film.

From high-definition pictures and video clips to complete Hollywood movies, a lot of multimedia content is downloaded, captured or stored in portable personal entertainment devices. Unfortunately, when consumers connect these portable devices to HDTV through standard analog interfaces, the image quality tends to decrease. Therefore, we need an independent portable high-definition audio-visual interface standard, so that these devices can be connected with high-definition TV through the standard HDMI port, and consumers can watch multimedia content on the high-definition big screen.

The special requirements of portable applications require a brand-new portable high-definition audio-visual interface standard on the market, including higher resolution, smaller connectors and lower power consumption. MHL technology is an audio-visual interface standard, which can connect portable consumer electronic devices to HDTV through the standard HDMI input port on TV.

In order to equip portable devices with MHL technology, manufacturers need to add an MHL transmitter IC to portable devices. Initially, portable devices supporting MHL technology will be connected to digital TV through docking stations or dongles. Dongle includes an HDMI-MHL bridge IC, which is used to convert the MHL media format with no loss of audio and video quality into a standard HDMI-compatible signal. Docking has a standard HDMI output interface, which can be directly plugged into HDTV. When the portable device is plugged into the docking station, the docking station can also transmit DC 5V power to the portable device to charge the battery, and has an optional USB connector to allow the portable device to exchange data with the PC.
