How many wire connectors does the projector have?

With regard to what cable the projector should use, we can first look at the projector interfaces, which generally include: computer input interface (VGA interface), audio output interface, video input interface, HDMI, USB interface, LAN port and control serial port. Many people feel headache when they see this place, because it often means that they correspond to all kinds of wires, and it is inconvenient to keep or use them.

Because the main function of the projector is to receive video signals, the commonly used connecting wires are:

1, VGA line. Projectors are generally connected to computers through VGA cables to transmit single analog video signals. They do not support live plugging or audio transmission, and are easily disturbed by power supply.

2.HDMI cable. At present, projectors have begun to use HDMI cable to connect computers. Its anti-interference and transmission resolution are higher than VGA cable, and it also supports audio transmission.

3. It is worth noting that many thin and light notebooks, including Apple series, have no VGA interface. At this time, you need to buy a VGA cable or adapter according to the notebook model to use the projector normally. If there is no adapter in the middle of the meeting, it will be embarrassing.

4. If you can't use the line, no one will like such a troublesome connection. At present, traditional projectors such as Epson, nec and Hitachi can realize wireless screen projection through screen projectors. BenQ, also a veteran manufacturer, has gone further. His intelligent business projector realizes the wireless screen projection on the whole platform, without accessories and software, and it can be directly projected by computers/tablets/mobile phones conveniently.
