The projector is often equipped with a plethora of connection ports divided into two groups: accepting input and output signals. The VGA in port typically accepts signals from the projector, while the VGA out port sends content to another projector.
Projectors have HDMI, VGA, and video connection connector types.
- Input signal types include HDMI, VGA, Video, S-Video, Audio In, and USB.
- Audio and VGA output ports
We frequently use three major signal receiving connectors to connect to computers, DVD players, or K +: HDMI, VGA, and Video. The quality of the signal ports varies as well. HDMI is preferable to VGA and video. You may output audio from the projector using the HDMI connector, which also supports audio. The remaining two connectors can only send images to the projector and cannot provide audio.
Check to see what ports are available on your player or computer before using the projector's ports. After that, the appropriate cable for that signal port can be selected or purchased. The HDMI connector should be preferred because it provides higher-quality images.
Furthermore, you should not unhook the projector's connectors while the system is running. Because HDMI connectors are frequently conductive, they can short-circuit when unplugged. The HDMI connector is readily destroyed in the long run, causing damage to the other components on the power board.
