Types of Projector Cables

There are mainly two kinds of projector cable according to the need of the user. They are-

  • Digital Cable
  • Analog Cable

Digital Cable

Digital cables are used for such devices which store digital videos. The most common kind of digital cables for transmitting video are given below:

1. HDMI Cables

The High Definition Multimedia Interface Cable (HDMI Cables) is the most commonly used and standard for A/V connections in this era as the HDTVs are used widely because of HD resolution video.

HDMI cable is used for establishing HDMI connections with various HDMI devices, including HDTVs and HDMI monitor displays.

This HDMI cables can broadcast both video and audio and signals other than other RCA cables. RCA cables need separate cables for audio and video and need extra three cables for connections.

2. DVI Cables

DVI (DVI-D, DVI-I, DVI-A) or Digital Visual Interference is an alternative to HDMI. It is basically a computer monitor connection. As DVI cables do not have a unified cable, it does not support audio transmission and video transmission together, but you’ll get an amazing result when you transmit video with it.

It was selected to be the successor to VGA back in 1999 when it was released. Among the three kinds, DVI-A is the analog kind, DVI-D is the digital type, DVI-I is the mixture of both analog and digital.

3. DisplayPort

DisplayPort is the second-best alternative to HDMI to transmit video in the case of HD A/V transmission. Like the HDMI port, it is a unified cable with two ports that can transmit both audio and video and is also composed of a high bandwidth HD interface. It was released in the year 2006.

This cable is designed to be used in most devices, including cameras, computers, projectors, gaming consoles, etc. Besides, it can be used with old devices too.

4. Mobile Handheld Devices

To project documents or recreational elements from smartphones, tablets, or Apple mobile devices, a projector is the most helpful device. The USB Connections used in this case are given below:


This single cable of USB port is mainly used for iOS devices and android phones that have their own connections. It is a 24 pin USB connector system. It was founded in the year 2014.

Through this cable, you can easily connect your android device with the projector.


It is actually designed for Apple devices or iOS operated devices. It is basically a power connector and computer bus.

It came to the market before Thunderbolt 3 or USB-C variant. It is mainly used for all kinds of iPads, iPhones, or iPods.

5. Thunderbolt 3

It is used for MacBook Pro. The main advantage is that any USB-C device can work with this cable. But only Thunderbolt devices can consume the maximum 40 Gbps speed.

Analog Video Cables

Such type of cables are used for analog video signals and transmission of audio data. Let’s discuss a bit more about them.

1. RCA Cable

The Radio Corporation of America or the RCA cable is the cable that can serve the oldest A/V connectors. It has yellow, red, and white plugs just like the old traditional ones.

It can connect devices with some of the oldest kinds of projectors. Sometimes you might need to use convertor video cables just in case.

2. Composite Video Cables

Composite cables are the analog video signal format for SD video (Standard Video). It was mainly used for old VCRs, CRT TVs, and Betamax players in the past.

But, composite video cables are also used for the projectors. Three variants named SECAM, PAL, and NTSC are based on region varying by speed, color difference, picture size, video signals, etc., from each other.

3. S Video Cable

Another name of S-Video is separate video or Y/C. For A/V connections, it is actually a signaling standard.

It is also used for three variants such as PAL, NTSC, and SECAM gives a broadcast of a 480i or 576i resolution. It will ensure better image quality for the user, but the color resolution is poor compared to composite video cable.

4. Component Video Cables

Component cables are fantastic for composite video content. It is also known as RGB connection or YPbPr. The primary process of this kind of cable is that with its help, the video signal is split into multiple channels.

It’s also a standard A/V cable. Component cables have three different colored signs and plugs, namely red, blue, and green. Component cable covers luminance, blue, red as well as green combinedly.

5. VGA Cable

VGA cables are a kind of video interface originated in 1987 by IBM for its PS/2 line of computers. With time, VGA became the standard for C video cards and computer monitors.

As PC clones were used instead of all other interfaces, VGA cable became the de facto video interface controller. It was meant to connect the PCs and Laptops with the projector.

Audio Cable For Projector

Audio cables for projectors are:

1. 3.5 mm

Used since the turn of the 20th century, it is such a cable with which almost everyone is familiar.

It is the metal audio phone jack used for cell phones and electrical musical instruments to connect with speakers or headphones.

2. Composite Audio Cable

It connects composite video to companion audio cables. It has two different kinds of white and red connectors for the left and right audio.

To produce better audio fidelity, it covers two different types of sounds from two various sources, and sometimes sounds come from only one speaker.

3. Optical Audio Cable

It is mainly used to deliver digital audio signals from CDs, DVDs, Video games, DAT recorders, computers, etc.

This sound is delivered to an AV receiver which decodes two channels for compressing surrounding sounds.

4. Bluetooth

It is a wireless medium existing in most devices, and through this, one can easily connect their machine with other audio devices or projectors.

Other Cables

Let’s also talk about some miscellaneous cables that might be used to connect the device with a projector without an adaptor:


These kinds of cables are used to use an old vintage projector, and with this, you can quickly turn the projector on or off. But this is not suitable for using other features of the projector.


These cables are mainly used with older versions of smartphones. One can easily connect any projector with this and use it to control the presentation slides remotely.


This cable can be used to link a smartphone, flash drive, external HDD to the projector in an easy way.


Ethernet cables allow a device to transmit audio and video data to the projector, just like HDMI, DVA, VGA, etc., connections. The major drawback of ethernet cables is that the image quality is inferior in this case.


So, these are the cables that are available in the market used with a printer. From the above details, I guess you already know which is the best for you.
