The Micro HDMI to HDMI Adapter converts a type D micro HDMI jack into a type A jack. High Definition Multi-Media Interface (HDMI) carries uncompressed digital video and audio signals on one cable from a digital video source to a display device. This provides the best detail, truest color and sound, and highest resolution. This adapter allows you to stream media, watch videos and view documents from a SmartPhone onto a flat panel display.
