Most digital enthusiasts know type-C interface, and it is estimated that they started with Android phones in 2015.
What many users may not know, however, is that there is also a Type-C interface on the computer’s display
If you are a friend who is just beginning to buy a monitor, the following can take a look at the most common types of monitor interface, combined with your own or ready to buy equipment, you can buy a monitor more practical.
What are the interfaces on the monitor?
The HDMI ports of newer monitors are generally above the HDMI1.4 protocol, and HDMI1.4 supports up to 10.2Gbps bandwidth of 3840x2160p/30Hz or 4096×2160p/24Hz video specifications.
HDMI2.0 adds 18Gbps 4K/60Hz video transmission, while the latest HDMI2.1 adds 48Gbps 10K/120Hz video transmission.
Since the DP interface was born in 2006, it has evolved seven generations of update and iteration. As early as 2009, DP1.2 has already supported dCI-4K (4096X2160) 60Hz video of 21.6Gbps.
DP1.3 supports 4K (3840X2160) 120Hz, 5K (5120X2880) 60Hz, and 8K (7680X4320) 30Hz, while DP1.4 supports 8K level (7680X4320) 60Hz output.
The latest DP2.0 goes further than the previous generation by supporting full color 4:4:4 resolution, including 30 bits per pixel (BPP), and hDR-10.
Type-c interfaces are not equal to USB3.0 interfaces
The first thing to realize is that the Type-C interface is not always the USB3.0 interface.
Type-c interface is an interface form and an external physical form, while USB3.0 is a transport protocol and an internal transport protocol.For example, the Type-C interface on many mobile phones still only supports THE USB2.0 protocol.
Let’s start with the most common PROTOCOLS for USB. USB has been around for 24 years since the release of USB1.0 in 1996.
Of these iterations, the most common by far are USB2.0, USB3.0, and USB3.1. USB2.0 supports a transfer rate of 480Mbps (now called hi-Speed, about 57MB/s).
USB3.0 supports transmission of 5Gbps, while USB3.1 goes to 10Gbps. At the same time, the power supply capacity also reaches 100W, which is a fast-charging interface.In fact, USB3.1 is also divided into Gen1 and Gen2, and the speed will be slightly different, so I won’t expand on that.
With all the interfaces described above, why introduce the transmission rate?
Because in addition to the computer output terminal, the display terminal like the monitor and the computer connected to the monitor cable to meet the corresponding bandwidth and video specifications, in order to ensure that you have a complete experience.
Since the usB-C specification was released in 2014, it has been used on many Android phones, laptops, desktops, monitors and even electronic devices like Nintendo SwTIch.
In terms of transmission rates, in addition to the most common USB2.0 and 3.0 mentioned above, the latest USB4.0 and lightning 3 protocols that support 40Gbps bandwidth can also be integrated into the Type-C interface.
In addition to the use of large bandwidth to transfer files, audio and video, it also supports up to 100W (20V/5A) charging power, plus small volume, both sides can be plugged in features.
So this is a very good solution, and a lot of mobile phone and computer manufacturers are also working on this interface, so going back to the monitor, what are the specific scenarios for monitors?
What are the application scenarios of the type-C interface of the display?
The most convenient application scenario should be the type-C interface of the monitor, which is connected to the Type-C interface of the laptop through a C-C wire. Now, in addition to the MacBook, many Windows laptops also support 65W charging through type-C interface.
If you have a type-C monitor at home or at work, you can buy one less HDMI cable and one less laptop charger when you go home or work.
This is very useful for people who want to keep their desktop clean, otherwise why are so many people using wireless keyboards and wireless mice?
Can be less than a wire, it is a contribution to the desktop wireless and minimization.Of course, the type-C interface mentioned above needs to be a fully functional interface.
The second application scenario is to transmit video signals and power supply to iPad through type-C interface, so that iPad can improve productivity to a certain extent.
When we talk about the iPad as a productivity tool, it is often questioned in terms of performance, screen size and keyboard touch experience.
If you extend the iPad to a larger screen, you’ll get some productivity gains.
In the third application scenario, android phones can be extended with a large screen through type-C interface and C-C wire. There are generally two modes for this kind of phone to project the display: mobile phone mode and computer mode.
Mobile phone mode means that the screen displayed on the monitor side is consistent with the content on the mobile phone side, while computer mode is similar to the “extended mode” in the dual screen of computer. At this time, you can use the mobile phone screen as the touch pad of mouse to operate the mobile phone APP just like computer software.
This scenario is expected to be used by relatively few people, but in some large meetings, it can be used to screen the contents of the mobile phone onto the big screen for the convenience of people in the meeting room to watch. This is an application scenario that Comes to my mind.
For a monitor, the most common types of interfaces are briefly introduced, and some higher-end or more productivity-oriented and commercially oriented monitors are equipped with full-featured Type-C interfaces.
Whether it’s pushing desktops wireless or boosting productivity on laptops and ipads, the interface is powerful and small.
