Using this display is easy. First, connect it to your Jetson Nano or Raspberry Pi 4B/3B+ via the HDMI port. Make sure to use a power supply that follows the PD protocol of 5 - 20V. You can start using it right away as it's plug-and-play. When using the touch function, you'll feel a smooth and sensitive response thanks to the 10 touch points. You can enjoy high - quality stereo sound from the built - in speakers. For maintenance, keep the display clean by using a soft, dry cloth to wipe it. Avoid using sharp objects on the screen to prevent scratches. Store it in a cool, dry place when not in use. And with the included leather case, it's easy to carry around.
