At present, there are four main types of video interfaces on the market: HDMI, VGA, DVI and DP. Among them, HDMI and DP interfaces are the most mainstream, and among these two, are you more familiar with HDMI cables?
This is the topic I want to talk to you about today, the same is the video interface, why is the popularity and popularity of HDMI higher than DP?
What is the difference between DP and HDMI?
The full name of the DP interface is Display Port, which is most commonly used as a display interface on laptops and graphics cards. DP supports higher resolutions and refresh rates, while also providing greater scalability. And DP supports SMD’s newly released multi-screen splicing technology. This interface can only be directly connected to the DP interface.
The full name of the HDMI interface is the high-definition multimedia interface, which is the most mainstream high-definition interface today. The most direct function is to support the transmission of video and audio, and the video will not be significantly compressed during the process, and the audio will not be damaged. Moreover, the HDMI interface has the characteristics of high transmission bandwidth, high resolution, small interface, uncompressed audio stream, and rich protocol.
Why is HDMI more popular and popular than DP?
01 HDMI supports simultaneous transmission of video and audio
HDMI is a standard developed by a group of TV manufacturers and has a low cost of use. DP was developed by a consortium of PC and chip manufacturers, and it was difficult to develop because it was not actively promoted. Moreover, HDMI only needs a line to transmit audio and video signals at the same time, without the need to convert before the signal transmission, which can ensure high-quality audio and video signals, and naturally it has been popularized on a large scale.
02 HDMI is widely used
In terms of application scenarios, HDMI is definitely the most extensive display class interface standard. HDMI can not only be used on TVs, projectors, set-top boxes, and even in car entertainment, home appliances and other aspects. Game consoles such as the popular PS5 or Xbox have adopted the HDMI interface as a signal output, which has become an indispensable and quick connection method for gamers.
The DP interface came out late, only in the PC field and high-end displays became popular. Therefore, in terms of displays, there are many types of devices that support the HDMI interface, and it is enough to explain why HDMI is more popular than DP.
03 HDMI standard update fast
Since the earliest version 1.0 was launched in 2002, the HDMI standard has been updated and upgraded to 1.3, 1.4, 2.0, 2.1, and in just over a decade, it has been updated and iterated so many times.
You know, the peak bandwidth of HDMI2.0 is 18Gbps, which supports 4K60Hz output mode. The peak bandwidth of 2.1 can reach 48 Gbps, and the maximum support is 10K resolution, and the gap in peak bandwidth has reached nearly 3 times.
Now everyone pays more and more attention to the quality of life, and at the same time, they will enjoy it more and more. HDMI2.1 also supports dynamic HDR, which allows viewers to take their senses of the film to a notch. At the same time, it also supports the VRR variable refresh rate function, which reduces the problem of screen stuttering, tearing and delay, bringing a smoother game experience and more screen detail.
It is precisely for the above reasons that this has led to the more popularity of HDMI lines than DP. Both have their own advantages, do you use an HDMI cable or a DP cable?
