HDMI, DisplayPort, DVI, VGA, Thunderbolt - Video Port Comparison

Hello everyone. In this video we're going to talk  about the different video adapter ports. Now these   ports are typically found in computers, monitors,  TVs ,and various video equipment/ So the first one   we're going to talk about is the VGA port, which  stands for video graphics array. Now this is an   older port that's been around for a while. In  fact it's been around since 1987. The VGA port   has 15 pins divided into three rows and it only  carries analog data. And because it only carries   analog data, the quality of the video may degrade  at higher resolutions and onger cable lengths. And   the end adapter will typically have a blue color.  The VGA port was used on the now-extinct bulky CRT   monitors, but you can still find VGA ports on  some new equipment, such as new LCD monitors.   But as I stated before, the VGA is an old design  and is slowly being phased out in favor of more   modern designs. And the next video port is called  DVI which stands for digital visual interface.   The DVI port has succeeded the VGA port. It was  developed in 1999 and it was designed to provide   uncompressed, high-quality video to LCD monitors.  Now there are three different versions of a DVI   standard There's DVI-A where the 'A' stands for  analog. And is used to send only analog signals.   There's DVI-D where the 'D' stands for a digital.  And this is used to send only digital signals.   And there is also DVI-I where the 'I' stands per  integrated. Now this is used to send both analog   and digital signals. Now on the ports that are  able to send digital signals, which would be the   DVI-D and DVI-I, there are two different options  in the DVI standard. There is single link and dual   link. Now the difference is that dual link  has six extra pins and these pins are what   allows for a higher resolution than single link.  Dual link DVI doubles the video bandwidth which   has a max resolution of 2560 x 1600, whereas  single-link DVI has a max resolution of 1920   x 1200. And the DVI end adapter will typically  have a white color. Another type of video port   is called HDMI which stands for a high-definition  multimedia interface. HDMI has a broad range of   use in electronic products, such as TVs, monitors,  laptops, mobile devices, and so on. It is in fact   the dominant video port that is used today. It  was developed in 2002 and it was designed for   transmitting uncompressed video and audio digital  data through a single cable. HDMI is one of the   best standards for high-definition in consumer  electronics delivering crystal-clear video as well   as audio. But in 2009, HDMI 1.4 was released and  it added another channel to HDMI for data which   has the capability of network communication. So  the connected devices that use this feature will   give HDMI the ability to send and receive data at  100 mbits/s Ethernet. So in addition to video and   audio on a single cable, the HDMI cable will have  another ability of Ethernet networking. But also   with HDMI 1.4, it also added support for 4K video  at 30 Hertz. And in 2017, HDMI 2.1 was released   which added support for a higher resolution and  refresh rates, with support for 4K video at 120   hertz and 8K video at 60 hertz. And it can also  support a max resolution of 10K for commercial   audio-visual systems and specialty usages. And  there's also the DisplayPort. The DisplayPort   debuted in 2006 and it was developed by VESA,  which stands for the video electronics standards   association. The DisplayPort was primarily  designed to be used for video. But in addition to   video it can also be used to carry USB and audio  data as well. It's a high-performance interface   that is meant to replace the older VGA and DVI  interfaces. And it can also connect by using   adapters to the older DVI, VGA, and HDMI ports.  One of the main advantages that it has over HDMI,   is that it has multi-monitor capabilities. The  DisplayPort allows you to use multiple monitors by   connecting them in a daisy-chain configuration. So  for example, if you wanted to use three monitors   on your computer, you would connect a cable from  the display port on your computer and the other   end to the first monitor. Then the first monitor  would connect directly to the second monitor.   And then the second monitor would connect to the  third monitor. So now you'll have three working   monitors while using only one DisplayPort on your  computer. And this is why the DisplayPort is more   focused for computer use than for other equipment  such as televisions. Another advantage that   DisplayPort has over HDMI is that it has a locking  mechanism that keeps the cable locked in place,   whereas HDMI does not have a locking mechanism.  And also unlike HDMI. the DisplayPort is a   royalty-free product. And in March of 2016,  DisplayPort 1.4 was released which has a   max resolution of 8K at 60 hertz. And the last  port we're going to talk about is Thunderbolt.   Thunderbolt is a high-speed technology interface  that outputs one serial signal from a combination   of PCI Express and the DisplayPort. Thunderbolt  is not just for connecting video, but it's also   used for attaching other external peripherals  as well. In fact it can daisy-chain up to six   devices. Thunderbolt was released in 2011 and  was mainly used in Apple products and now it   has become available to PCs. Now there are three  different versions of Thunderbolt. Versions 1 & 2   use the same connector as the mini DisplayPort.  And version 3 uses a USB type-C connector.
