Most of the digital enthusiasts know Type-C interface, it is estimated that from the Android phone in 2015.
But it is estimated that many users do not know is that the computer side of the monitor also has a Type-C interface.
If you are a friend who is just starting out and wants to buy a monitor, you can take a look at the introduction of the most common types of interfaces for monitors respectively, and combine them with the equipment you own or are planning to purchase to get more of a foot in the door when buying a monitor.
What interfaces are generally available on the monitor?
Generally now the new monitor will have these interfaces: HDMI, DP, USB-A, USB-C, 3.5mm and power interface, like VGA interface and DVI interface and other relatively old school interface has less appear in the current monitor.
Like the USB protocol, the HDMI interface also has several different protocols: HDMI 1.1/1.2, HDMI 1.3, HDMI 1.4, HDMI 2.0, HDMI 2.1.
HDMI 1.4 supports up to 10.2Gbps bandwidth of 3840x2160p/30Hz or 4096×2160p/24Hz video specifications.
HDMI 2.0 adds a bandwidth of 18Gbps 4K/60 Hz video transmission, while the latest HDMI 2.1 adds support for 48Gbps bandwidth of 10K/120 Hz video transmission.
The DP interface has evolved over seven generations since its birth in 2006, with DP 1.2 supporting DCI-4K (4096X2160) 60 Hz video at 21.6Gbps back in 2009.
DP 1.3 then supports 4K (3840X2160) 120hz, 5K (5120X2880) 60hz and 8K (7680X4320) 30hz, while DP 1.4 supports 8K level (7680×4320) 60Hz output.
The latest DP 2.0 takes the previous generation a step further by supporting full color 4:4:4 resolution, including 30 bits per pixel (bpp), and also supports HDR-10.
Type-C interface is not equal to USB 3.0 interface
The first thing to know is that the Type-C interface is not all USB 3.0 interface.
Type-C interface is an interface form, is an external physical form, while USB 3.0 is a transmission protocol, is an internal transmission protocol. For example, many phones on the Type-C interface still only support the USB 2.0 protocol.
Let’s start with what protocols are most common with USB. From the release of USB 1.0 in 1996, the USB interface has gone through 24 years.
In so many iterations of the version, the most common is currently USB 2.0, USB 3.0 and USB 3.1, USB 2.0 supports 480Mbps (now called Hi-Speed, about 57MB / s) transfer rate.
While USB 3.0 supports 5Gbps transmission, USB 3.1 goes to 10Gbps, while the power supply capacity also reached 100W, belonging to the fast charging interface. This in fact, USB 3.1 is also divided into Gen1 and Gen2, the speed will be slightly different, here will not expand on.
Above the introduction of so many interfaces, why do we need to introduce the transmission rate?
Because in addition to the computer output side, the display side like the monitor and the computer connected to the monitor wire have to meet the appropriate bandwidth and video specifications to ensure you have a complete experience.
Since the release of the USB-C specification in 2014, many Android phones, laptops, desktops, monitors and even gaming consoles such as Nintendo SwTIch and other electronic devices have begun to use this interface.
And in the transfer rate, in addition to the most common USB 2.0 and 3.0 mentioned above, like the latest support for 40Gbps large bandwidth USB 4.0 and the same 40Gbps bandwidth Thunderbolt 3 protocol can also be integrated in the Type-C interface.
In addition to being able to use the large bandwidth to transfer files, audio and video, it also supports up to 100W (20V/5A) of charging power, plus the compact size and front and back are pluggable.
So this is a very good solution, and many cell phone and computer manufacturers currently have a force on this interface, so back to the monitor, which for the monitor, what are the specific application scenarios?
What are the application scenarios for the monitor’s Type-C interface?
The most convenient application scenario would be to connect the monitor’s Type-C interface to the notebook’s Type-C interface through a C-C cable. Now, in addition to Apple’s MacBook, many notebooks in the Windows camp also support 65W charging through the Type-C interface.
If you are equipped with a monitor with a Type-C port at home or at work, you can buy one less HDMI cable and bring one less laptop charger when you go home or back to work.
This is very practical for the pursuit of desktop tidy friends, otherwise why so many people are using wireless keyboard and wireless mouse?
Can less a wire, is a contribution to the desktop wireless and minimalist. Of course, the above-mentioned Type-C interface needs to be a fully functional interface.
The second application scenario is to transmit video signals and power to the iPad through the Type-C interface, allowing the iPad to enhance productivity to a certain extent.
When we talk about the iPad as a productivity tool, it is often questioned on several aspects of product performance, screen size and keyboard touch experience.
If the iPad is given a large screen extension, then it gets a certain degree of boost in productivity.
The third application scenario can be through the Type-C interface and C-C cable to Android phones to expand a large screen, this phone to the monitor screen projection generally has two modes: cell phone mode and computer mode.
Cell phone mode is the monitor side of the display screen and the phone side of the same content, computer mode is similar to the computer dual-screen “extended mode”, at this time you can use the phone screen as a mouse touchpad, like the operation of the computer software to operate the phone APP.
This application scenario is less likely to be used, but in some large meetings, you can use this to cast the phone content to a large screen, convenient for people in the conference room to watch, this is an application scenario that I can think of.
Summary.
For a monitor, the most common types of interfaces are briefly introduced to you once, in some of the more high-end or positioning bias productivity and business monitors, will also be equipped with a full-featured Type-C interface.
Whether it is to promote the desktop wireless, or to enhance the productivity of notebooks and iPads, this interface is powerful and compact.
