Most digital enthusiasts know the Type-Ch interface, and they probably started with Android phones in 2015.
But it is estimated that many users don’t know that there is also a Type-C interface on the monitor on the computer.
If you are a friend who is just starting out and want to buy a monitor, you can take a look at the introduction to several of the most common interfaces of the monitor. Combined with the equipment you own or are ready to purchase, you can be more at ease when purchasing a monitor. What interfaces are generally present on
monitors?
Generally, there are several interfaces on new monitors now: HDMI, DP, USB-A, USB-C, 3.5mm and power interfaces. Interfaces such as VGA interface and DVI interface are rarely seen on current monitors.
is the same as the USB protocol, HDMI interface also has several different protocols: HDMI 1.1/1.2, HDMI 1.3, HDMI 1.4, HDMI 2.0, HDMI 2.1.
The HDMI interfaces equipped with newer monitors are generally above the HDMI 1.4 protocol. HDMI 1.4 supports up to 10.2Gbps bandwidth video specifications of 3840x2160p/30Hz or 4096×2160p/24Hz.
and HDMI 2.0 adds 4K/60 Hz video transmission with a bandwidth of 18Gbps, while the latest HDMI 2.1 adds 10K/120 Hz video transmission with a bandwidth of 48Gbps.
, and the DP interface has evolved from seven generations of updates since its birth in 2006. As early as 2009, DP 1.2 already supported 21.6Gbps DCI-4K (4096X2160) 60 Hz video.
DP 1.3 supports 4K (3840X2160) 120hz, 5K (5120X2880) 60hz and 8K (7680X4320) 30hz, and DP 1.4 supports 60Hz output at 8K level (7680x4320).
, while the latest DP 2.0 is a step further from the previous generation, supporting full color 4:4:4 resolution, including 30 bits per pixel (bpp), and also supporting HDR-10.
Type-C interface is not equal to USB 3.0 interface
First of all, we need to know that Type-C interfaces are not all USB 3.0 interfaces.
Type-C interface is an interface form, an external physical form, while USB 3.0 is a transmission protocol, an internal transmission protocol. For example, the Type-C interface on many mobile phones still only supports the USB 2.0 protocol.
First talk about what protocols are most common with USB. It has been 24 years since USB 1.0 released in 1996.
Among the iterations of so many versions, the most common ones are USB 2.0, USB 3.0 and USB 3.1. USB 2.0 supports a transfer rate of 480Mbps (now called Hi-Speed, about 57MB/s).
and USB 3.0 supports 5Gbps transmission, while USB 3.1 reaches 10Gbps, and the power supply capacity reaches 100W, which belongs to the fast charging interface. In fact, USB 3.1 is also divided into Gen1 and Gen2, and the speed will be slightly different, so I won’t go into it here.
so many interfaces introduced above, why do you need to introduce the transmission rate?
Because in addition to the computer output, display terminals like monitors and cables connected to the computer must meet the corresponding bandwidth and video specifications to ensure that you have a complete user experience.
Since the release of the USB-C specification in 2014, many electronic devices such as Android phones, laptops, desktops, monitors and even gaming consoles such as Nintendo Swtich have begun to use this interface.
In terms of transmission rate, in addition to the most common USB 2.0 and 3.0 mentioned above, the latest USB 4.0 that supports 40Gbps large bandwidth and the same 40Gbps bandwidth Thunderbolt 3 protocol can also be integrated into the Type-C interface. In addition to being able to use large bandwidth to transmit files, audio and video,
also supports charging power up to 100W (20V/5A), plus the small size and pluggable front and back sides.
So this is a very good solution. At present, many mobile phones and computer manufacturers are also making efforts on this interface. So, back to the monitor, what specific application scenarios are there for the monitor? What are the application scenarios of the Type-C interface of the
monitor? The most convenient application scenario of
should be connected to the Type-C interface on the laptop through the Type-C interface of the monitor through a C-C cable. Now, in addition to Apple's MacBook, many laptops in the Windows camp also support 65W charging through the Type-C interface.
If you have a monitor with Type-C interface at home or in your company, you can buy less HDMI cable and less laptop charger when you go home or in your company.
This is very practical for friends who pursue clean desktops, otherwise why are so many people using wireless keyboards and wireless mice?
can have one less wire, which is a contribution to desktop wirelessization and simplification. 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 the iPad through the Type-C interface, so that the iPad can improve productivity to a certain extent.
When we talk about iPad as a productivity tool, it is often questioned in terms of product performance, screen size and keyboard touch experience.
If the iPad is expanded to a large screen, the productivity will be improved to a certain extent.
The third application scenario can expand a large screen to Android phones through the Type-C interface and C-C cables. This kind of phone generally has two modes to project screens to the monitor: mobile phone mode and computer mode.
mobile phone mode means that the screen displayed on the monitor is consistent with the content of the mobile phone, and the computer mode is similar to the "extended mode" in the dual screen of the computer. At this time, you can use the mobile phone screen as the mouse trackpad and operate the mobile phone APP like operating the computer software. The application scenario of
is probably less likely to be used by people, but in some large-scale conferences, this can be used to cast mobile phone content onto a large screen to facilitate people in the conference room to watch. This is an application scenario I thought of.
Summary:
For a monitor, the most common types of interfaces are simply introduced to you. For some more high-end or more productive and commercially available monitors, they will also be equipped with a fully functional Type-C interface.
Whether it is promoting desktop wirelessization or improving laptop and iPad productivity, this interface is powerful and compact.
For the Type-C interface, if you still have any application scenarios, you can also leave a message in the comment area to discuss.
