SUPERIOR STABILITY: Built-in active IC chip converts HDMI digital signal to VGA analog signal. Connect the included Micro USB power cable to the adapter and computer USB port or wall charger to provide additional power for devices with low-power HDMI ports such as SONY PS4, Apple MacBook Pro with Retina Display, Mac mini, and Apple TV. It is NOT a bi-directional converter and cannot transmit signals from VGA to HDMI
