30 series graphics cards, PS5, Xbox series S console and other next-generation devices have been released, the current display used on the HDMI and DP interface in the future who will become the mainstream?
This special section will try to analyze this issue, the results will certainly be unexpected, come and see.
First for you to briefly introduce the current state of the interface, the current display interface will be equipped with HDMI and DP interface, and VGA interface and DVI interface can only be seen in some low-end positioning of the display, basically can be determined to exit the stage of history.
The current monitor mainstream interface HDMI interface for the left and right symmetrical trapezoid. TV, computer, projector support it, is currently a more common connection port.
DP interface and HDMI interface, compared to the “dedicated” a lot. It was developed for the computer field at the beginning, so in addition to the monitor and graphics card outside the electronic equipment, almost can not find the DP interface figure.
In addition to the difference in the scope of use of the two interfaces, there is also a big difference in the output rate and its own iteration.
HDMI has been upgraded several times, and now there are two common HDMI 1.4 and HDMI 2.0, of which HDMI 1.4 bandwidth is low, only 10.2Gdps, can only play 4K, 30 fps video; while HDMI 2.0 bandwidth is low, only 10.2Gdps, only 4K, 30 fps video.
HDMI 2.0, on the other hand, upgrades the bandwidth to 18Gdps, and the frame rate of 4K video playback is increased to 60 fps.
The 30 series graphics cards equipped with HDMI 2.1 is a new generation of HDMI interface standard, it is a greater upgrade, the bandwidth reached 48Gbps, up to support the standard 4K resolution at 240Hz screen display, is several times the previous generation.
And after several iterations on the DP interface side, the current mainstream protocol has two kinds of DP1.2 and 1.4.
DP1.2 supports a bandwidth of 21.6Gbps, while DP1.4 supports a bandwidth of 32.4Gbps.
The DP interface also has a long-established protocol content but not yet popular DP 2.0 interface standard. It supports a bandwidth of 80Gbps and up to 8K/75Hz or 4K/240 Hz screen display.
From now on, there are many devices using HDMI interface with strong compatibility and the interface itself is constantly iterating. The latest HDMI 2.1 will also surpass the DP interface in terms of transmission bandwidth, making it possible to display a higher specification screen.
And with the 30 series graphics cards and next-generation gaming consoles coming to market, HDMI 2.1 interface will also accelerate the pace of market penetration.
However, the DP interface side there is a killer app has not yet come out.
It is currently part of the display equipped with Type-C interface, which is based on the DP1.4 protocol. This round and flat, positive and negative can be inserted into the interface think we should not be unfamiliar with it.
It has a lot of advantages, small size, regardless of the positive and negative, fast transmission speed, power supply capacity, etc., very convenient in use.
It is foreseeable that the future trend is bound to Type-C interface to capture a large number of electronic devices to achieve a large unified interface.
Take the AOC U27U2 I’m using now as an example, I can connect to the monitor through the Type-C interface on my laptop.
At the same time to achieve the notebook charging, data transfer, video output and other functions. The mouse cable, keyboard cable, charging cable and headphone cable are all connected to the monitor for use. When I have a meeting or leave work, I unplug the Type-C cable on the laptop and go with it, not to mention how convenient it is.
Samsung, Huawei and Hammer and other manufacturers are also actively promoting the linkage of cell phones and monitors, some of the phones that support desktop mode can be connected to the phone through the Type-C interface on the monitor, and other USB ports connected to the mouse and keyboard.
The phone will switch to PC mode, at this time the phone is a mini host, you can use WPS to edit documents, send and receive e-mail, but also to find information on the Internet, leisure time can also use the large size screen for games, watching film and television entertainment.
This is on the HDMI interface or DP interface, is completely unable to achieve things.
The current Type-C interface supports the DP1.4 protocol, the future DP 2.0 protocol after the launch, maybe the DP interface will directly become Type-C interface shape, which undoubtedly makes the DP interface in the future use, more convenient and flexible than HDMI.
On the contrary, the HDMI interface, due to the need to consider the TV, projectors and other equipment connection needs, so you have to stick to the HDMI interface shape.
DP interface, as mentioned earlier, it is developed for the computer field. So the choice on the interface shape is more free.
Next, equipped with Type-C interface of electronic devices will certainly be more and more. If your monitor does not yet support the Type-C interface, then you need to consider replacing a monitor that supports this interface, because the future has arrived!
