About The HDMI, VGA, DVI, DP Interface Knowledge Of The Monitor, The Most Comprehensive And Most Easy To Understand Comparative Analysis In History!

At present, the interface of the display has DP HDMI VGA DVI, and the shapes of these interfaces are also different. When purchasing a host, we generally need to consider whether the host's graphics interface matches the monitor interface. For example, if your graphics card interface is HDMI+DP, and your monitor has only VGA interface, then it is awkward. The current public version of the graphics card will have HDMI and DP interfaces, but the general graphics card manufacturer will add a DVI interface on the graphics card, but the newly purchased display interface will also carry these three interfaces, VGA is currently It has been eliminated. This is because the VGA transmits an analog signal. In addition to the different shapes, what are the big differences between these interfaces? Today MSL-force shares HDMI, VGA, DVI, DP interface knowledge, with you a better understanding of various interfaces.( In the related homepage, I have another article about introduction and comparison between DP and HDMI.)
From the perspective of interface performance, the performance of the interface is DP>HDMI>DVI>VGA.
Monitor interface:
NO.1 DP
DP, DisplayPort, is a high-definition digital monitor interface standard that can be connected to a computer and monitor, or to a computer and home theater. The DP interface can be understood as an enhanced version of HDMI, which is more powerful in terms of audio and video transmission. In the current situation, there is not much difference in performance between DP and HDMI. If you use 3840*2160 resolution (4K), HDMI can only transmit 30 frames due to insufficient bandwidth, and DP has no problem. In May 2006, the Video Electronics Standards Association (VESA) confirmed the 1-0 version of the standard, and upgraded to the 1st and 1st editions after half a year, providing support for HDCP. The 2:0 version is also planned to be launched this year; as HDMI With UDI's competitors and potential successors to DVI, DisplayPort has won support from industry giants such as AMD, Intel, NVIDIA, Dell, HP, Lenovo, Philips, Samsung, and it is free to use.
NO.2 HDMI
HDMI can transmit high-definition graphics signals as well as audio signals. Generally speaking, the home will receive TV and has strong anti-interference. The HDMI interface also transmits digital signals, so the effect of video quality and DVI interface transmission is basically the same. Currently the highest HDMI2.1 standard, supporting 8k 60Hz and 4k 120Hz, the resolution can reach up to 10K. It also supports high dynamic range HDR and increases bandwidth to 48Gbps. If the monitor has a monitor function and an audio system, the HDMI interface can simultaneously transmit the computer video and audio signals to the monitor. HDMI has three interfaces. Mainly considering the needs of the equipment. If the digital camera is small and requires a small interface, use micro HDMI.
NO.3 DVI
The DVI interface has two standards, 25-pin and 29-pin, as shown in the following figure. Intuitively, there is no difference between the two interfaces. DVI is a high-definition interface, but without audio, that is, DVI video wiring only transmits picture graphics signals, but does not transmit audio signals. The DVI interface transmits digital signals that can transmit large resolution video signals. DVI connects to the computer graphics card and monitor without conversion, so there is no loss of signal. However, the DVI interface also has many drawbacks: since it was originally designed for the PC side, it has reserved a lot of pins to support the simulation for poor compatibility with TV and only supports 8-bit RGB signal transmission and compatibility considerations. The device causes the interface to be bulky. At present, a better DVI interface can transmit 2K images, but it is basically the limit.
NO.4 VGA
VGA is an analog signal, which has been eliminated by the mainstream. This is why we can see the other three interfaces on the latest graphics card but can't see the VGA interface. DVI, HDMI and DP are digital signals, which is the current mainstream. VGA's 15-bit video interface is mainly used for old-fashioned computer output to old-fashioned monitors, so we often use an HDMI or other interface to VGA interface adapter. The VGA output and the transmission of the analog signal, we all know that the computer graphics card produces a digital signal, the monitor also uses digital signals. So using a VGA video interface is equivalent to undergoing a digital-to-analog conversion and a single-modulo conversion. Signal loss, the display is more blurred.
Now the monitor interface is generally DP HDMI VGA DVI four kinds, of which VGA is the interface that has been eliminated, but a few low-end monitors also have this interface. Most monitors are VGA+DVI dual interface, and also have VGA+HDMI dual interface. The DP interface can only be seen on a few high-end monitors.
Therefore, different devices in life need to use different interface connections. We often use DP to DVI or DP to HDMI or DP TO VGA or BIG DP TO MINI DP conversion lines because the display in the home is old-fashioned. MSL-force wants to recommend the following products with strength and high quality products to meet the above mentioned needs.
