This adapter High Speed HDMI with Ethernet from Delock complies with the latest HDMI standard and combines fast data transfer and audio / video and Ethernet connection in one. The micro HDMI-D connector was developed specifically for the new generation of cell phones and digital cameras and is used for the transfer of data, such as videos, images, etc.. So you can e.g. convert the micro HDMI-D port of your cell phone into a HDMI-A port and connect it to your TV with the help of an optional HDMI (HEC) cable. The display content of your cell phone will then be transferred to a larger screen.
