[Wireless HDMI Transfer] Conventional products are wired, requiring many cables, and it takes a considerable amount of time just to connect them. It's not uncommon for it to take even longer before you can actually use them. Our wireless HDMI requires no complicated setup or connections, and can be used without cables, freeing you from them. By combining the receiver and transmitter, you can simply plug them in to output the screen of a laptop or DV to another monitor. [Connection Method & Plug and Play] Easy to use, just plug it in! No setup/WiFi required. The connection method is as follows: 1. Connect the HD port of the receiver to the video input port of a display device such as a display or TV. 2. Connect the charging cable to the Micro power supply port of the receiver and plug it into a power adapter or Micro power supply port (voltage 5V current 2A), and turn on the power switch of the receiver. (Note: Do not press the function button on the receiver. It has a privacy mode, so it can be disconnected.) 3. Adjust the HD signal source of the display or TV to the corresponding HD port, turn on the receiver, and wait for the screen to appear to confirm the connection is successful. 4. Send the transmitter to a computer or a device with an HD video output function. Wait for about ten seconds after the lamp flashes rapidly, and the projection will be completed.
