Careful people may\nfind that in the last decade of development, the interface of display devices\nhas undergone tremendous changes! We used a lot of blue VGA interface, and then\nthere is a white DVI interface. When encountering different interfaces, we have\nto buy adapters for transfer. Later, there was an interface such as HDMI, and\nnow there are DP and USB Type-C interfaces. So, with so many interfaces, what\nis the difference? Which one should we use?<\/p>\n\n\n\n

VGA Port<\/p>\n\n\n\n

The VGA interface\nis also known as the D-Sub interface. In the era of CRT displays, the VGA\ninterface is a must. Because CRTs are analog devices, and VGAs are analog\nprotocols, they are of course matched for use. The VGA interface adopts a\n15-pin pin structure, which transmits signals such as components and\nsynchronization. It is the interface used by many old graphics cards, notebooks\nand projectors. Later, the LCD display appeared, also with a VGA interface. The\ndisplay has an A\/D converter built in to convert the analog signal to a digital\nsignal for display on the LCD.<\/p>\n\n\n\n

DVI Port<\/p>\n\n\n\n

There are many\ntypes of DVI, DVI-A, DVI-D, DVI-I on the interface, and can be divided into\nsingle channel and dual channel. The DVI-A (DVI-Analog) interface only\ntransmits analog signals. The essence is the VGA analog transmission interface\nspecification, which is often used to transfer the DVI-I output of the graphics\ncard to the VGA display interface. The DVI-D (DVI-Digital) interface is a pure\ndigital interface and is not compatible with analog signals. DVI-I\n(DVI-Integrated) interface, compatible with DVI-I and DVI-D plugs, compatible\nwith digital and analog signals. Their interface shapes are different and\ncannot be inserted if the interfaces do not match.<\/p>\n\n\n\n

HDMI Port<\/p>\n\n\n\n

The HDMI interface\nwas introduced in 2002 and has now evolved to the HDMI 2.1 standard. With the\ndevelopment of the industry, the HDMI 2.1 standard has been able to support 4K\n120Hz and 8K 60Hz, and supports high dynamic range imaging (HDR), which can be\noptimized for scenes or frames. Backwards compatible with HDMI 2.0 and HDMI\n1.4. The main thing is that it is transmitted simultaneously with video and\naudio.<\/p>\n\n\n\n

Many of today’s\nmonitors have built-in speakers, and with an HDMI cable, you can simultaneously\ntransfer images and sounds, which is a big advantage of HDMI. Because of this,\nHDMI is the most common interface for today’s displays. We should also prefer this\ninterface when we use it. There are several types of HDMI on the physical\ninterface. There are mainly standard HDMI interface, mini HDMI interface and\nMicro HDMI interface. For long-distance transmission of HDMI cable, the wire is\ngenerally hard, so try to use a device with a standard HDMI interface to get a\nstable connection. The Mini HDMI interface and Micro HDMI interface are more\nsuitable for small devices.<\/p>\n\n\n\n

DP Port<\/p>\n\n\n\n

The DP (Display\nPort) interface is a competitor of the HDMI interface. On some graphics cards\nand displays, in addition to the HDMI interface, it also has a DP interface. At\npresent, the DP interface has been developed to version 1.4, which can transmit\n10bit 4K 120Hz video, and can also support 8K 60Hz video. DP1.4 is compatible\nwith the USB Type-C interface, which means that we can use the DP1.4 protocol\nto simultaneously transmit HD video while USB 3.1 is transmitting data. From a\ntrend perspective, this is very beneficial for promoting the upgrade of\nperipheral audio and video equipment. Moreover, the DP interface can also\ntransmit sound synchronously on a single line to achieve the use of the display\nsound.<\/p>\n\n\n\n

Type-C Port<\/p>\n\n\n\n

The USB interface\nhas long been known. In the past, the USB interface was designed to transmit\ndata, so it is very common in the use of storage devices such as mobile hard\ndisks. Now USB 3.1 Gen2 has reached 10Gbps speed, and the design standard can\nalso meet the video and data transmission, so on some monitors, the USB 3.1\ninterface can also be found. The current USB 3.1 interface has been able to\nmeet the resolution display of 4K 30P, which is roughly the same level as\nHDMI1.4. However, it will be upgraded in the future and will become the most\ncommon display transmission method. It should be noted that USB 3.1 Gen1 is USB\n3.0, and USB 3.1 Gen2 is the real USB 3.1.<\/p>\n\n\n\n

The advantage of\nthe Type C interface is that it can be plugged and unplugged. Some Type C\ninterfaces also have the functions of data, power and signal transmission. When\napplied to the display, it can bring a lot of convenience. Type C notebook\nusers can charge and connect the display through an interface, and can also use\nthe USB interface extended on the display, greatly reducing the burden on the\nnotebook.<\/p>\n\n\n\n
