DisplayPort

What is DisplayPort?

DisplayPort (left in the image above) is a 20-pin digital video cable developed by the Video Electronics Standards Association (VESA). It is one of the most advanced cables on the market today and was specifically designed for use with computer monitors.

What is Mini DisplayPort?

Mini DisplayPort (right in the image above) is a downsized version of DisplayPort that is used on devices too small to fit a standard DisplayPort.

What is Thunderbolt?

Thunderbolt is an off-shoot of Mini DisplayPort developed by Intel & Apple most commonly seen on Apple products. While Thunderbolt and Mini DisplayPort look the same, Thunderbolt is much more advanced. Mini DisplayPort is not forward compatible with Thunderbolt, but Thunderbolt is backward compatible with Mini Displayport.

What is DisplayPort 1.2?

DisplayPort 1.2

DisplayPort is the latest and greatest audio/video cable available today. While it does have many similarities with HDMI, DisplayPort is even more powerful. Whereas HDMI was designed as a multi-purpose cable capable of working with any and all electronics, DisplayPort was specifically created with computer monitors in mind. Capable of supporting HD video at even higher resolutions than HDMI, there is no better choice than DisplayPort when cable quality is your primary concern.

DisplayPort Specifications

The original DisplayPort cable, version 1.0, was developed by VESA (Video Electronics Standards Association) and introduced in May 2006. Since then, several newer versions with various improvements have been developed and replaced their older counterparts. Many DisplayPort cables on the market are not marked with a version number, so knowing the age of the cable is the best way to tell how well it performs. These days, users would be unlikely to come across a cable older than version 1.2. This was the first version of DisplayPort to fully outshine HDMI, being capable of supporting higher maximum bandwidth.

Like HDMI, DisplayPort is capable of supporting audio/video instead of being video-only like many of its competitors. Despite these differences, DisplayPort connections can be adapted to other video formats including HDMI, DVI, and VGA. This can be done with an adapter cable or independent adapters can

Audio and video cables go hand-in-hand, often being paired together. Some cables can even transmit audio and video on just one line. Over time a lot of new audio and video cables have been introduced, so the cable you need will often depend on the age of the equipment you are using. Most TVs, computers, and other devices can use multiple types of audio and video connections, so it is good to be able to identify them and know your options.

Audio-only

3.5mm

3.5mm, also called ⅛” cables, is one of the most common audio cables. They are sometimes called “headphone jacks”, being the type of connection used for headphones. These ports are frequently found on cell phones, computers, and televisions.

There are a few different versions of 3.5mm: TS, TRS, and TRRS. TS cables will have one ring, dividing the metal sections into two conductors and are most often used for mono connections like microphones. TRS has two rings to give it three conductors, allowing them to be used for stereo connections such as speakers. TRRS has three rings for four conductors to support stereo aud
