USB input: connect a USB flash drive, play files in the USB flash drive/mobile hard disk, and some projectors with Android systems can also use the USB interface with a mouse and keyboard
TF card: Support memory card, play files in the memory card.
HDMI input (high definition input): High Definition Multimedia Interface (English: High Definition Multimedia Interface, HDMI) is a digital video/audio interface technology, a special digital interface suitable for image transmission, which can transmit audio and image signals at the same time
VGA input: The VGA interface adopts asymmetrically distributed 15pin connection. The VGA interface has many advantages, such as no crosstalk and no circuit synthesis separation loss. (Transfer images, not audio)
Standard video input (RCA): Also known as AV interface, it usually uses RCA (commonly known as lotus head) for connection. The AV interface realizes the separate transmission of audio and video, but because the AV interface still transmits a mixed video signal of
luminance/chrominance (Y/C), the display device still needs to perform luminance/color separation and chrominance decoding on it. Can be imaged.
Audio output interface: the sound of the projector can be output to other audio equipment or headphones
High-speed quick-band interface (RJ45): you can directly connect to the network cable, surf the Internet, watch online videos, news, and TV
