Using this adapter is super easy. First, find the Micro - HDMI port on your device, such as your Raspberry Pi 4, tablet, or phone. Then, plug one end of the adapter into the Micro - HDMI port. Next, connect the other end of the adapter to a device with a standard HDMI port, like a TV or a monitor. Make sure all the connections are secure. When it comes to maintenance, keep the adapter in a dry and clean place. Avoid bending the cables too much as it might damage the internal wiring. Also, don't expose it to extreme temperatures. If you notice any problems with the video quality, check the connections first and make sure both devices are properly powered on.
