Today'smonitorThe resolution has grown from 1080P to 8K, and users pay more attention to itHDRHigh dynamic display enhancement technology and color gamut;The overall workmanship has changed from a wide chin to a few millimeters of narrow borders. Thanks to strict interface specifications and protocols, its attached functions can gradually meet the daily use of users. DP, HDMI and other video transmission functions are also added toUSB-C port.
In addition to the display screen, can the display screen become a docking station that can display the screen?the near future,chargeHeadnet got a model from Redmi that supports Type-C reversechargeOfmonitor, with high dynamic display enhancement technology and globalDCDimming and other functions, let's take a look at this RedmichargeActual devicechargeHow about it!
Product Introduction
Clear thinking, first look at the packaging.
RedmimonitorThe outer package is corrugated box, and the front is only printed with the product model, specification, name andmonitorOutline frame, model: RMMNT27NU.
List of product accessories, exceptmonitor, base, manual and warranty card, power cable, C2C and HDMI video transmission cable are also included.
screenThe display appearance is also one of the most critical, and the big screen game office is really cool.
From the front of the display, the pure black coating is frosted, with fine texture and smooth touch;The flat black micro narrow frame design improves the appearance of the picture, and can also avoid dust deposition to a certain extent;The base support supports pitching, lifting and rotation.
The overall length of the display is about 61cm.
The overall height of the display is about 36cm.
The diagonal length is about 71cm.
Compared with the 24 inch display, the display bracket and height are similar,screenThe overall appearance should be much larger.
Display bracket
Long sitting requires a proper rest, and the function of the randomly provided stent is also very ergonomic.
It supports height adjustment, which is also the most commonly used adjustment method for users.
The second is the 90 ° axis rotation function, which can be used as a vertical screen, and is relatively friendly to dual screen or code writing users.
The function of front and back pitching is unnecessary but necessary. Different angles can be adjusted for people with different sitting positions to protect the spine.
Naturally, the display should rotate left and right. The measured rotation angle is about 45 °. If you encounter any problem or happy thing, you can share it with your colleagues by rotating, but pay attention to whether the length of the access wire is supported.
port configuration
The rich interface configuration determines whether additional docking stations are needed for later expansion.
Two pieces are configured on the bottom of the housing at the connection of the Redmi 4K 27 inch display bracketUSB-A port, 2 HDMI 2.1 (TMDS protocol), 1 DisplayPort output and 1USB-C port, the actual function of each port will be tested later.
VESA installation system
Now, in addition to the lifting table, the display bracket arm is the most commonly used by users, which can adjust the sight distance of comfortable office and games at will.
The display body and the bottom bracket adopt a circular embedded snap connection design, which is relatively simple and easy to use, and has good stability.
Ordinary users don't know what the four hole fixing interface screw on the display is for. In fact, our common VESA MIS-D, 100/75, and C compliance displays will be equipped with a hole type of 100 x 100 mm or 75 x 75 mm. M4 screws will be used to fix the bracket to the display. This is a common interface for displays weighing less than 14 kg. The bracket arm will be selected according to the appropriate size.
standby power
Standby is generallyscreenThe sleep state is turned off, but the standby power also needs to be tested. After all, saving power is saving money.
First, inscreenTurn to the customized standard brightness mode, and the standby power consumption of the display is about 29.11W.
Video expansion
The main function of the display is to display pictures. Let's see how the picture transmission performance of other devices is.
Notebook computer
HDMI video transmission is naturally no problem, and it is also easy to use it as a secondary screen.
Although the HDMI interface is castrated, the MacBook Pro is equipped with a full function lightning interface;Actual use displayUSB-There is no problem with the C connection display, provided that the notebook needs to supportUSB-C video output;In addition, the Xiaomi 4K 27 inch display supports the FOR MAC compatibility mode, which can minimize the visual difference between the display and the MacBook screen after being turned on.
The connection display specification is 4K 60Hz, the input is HDMI signal source, and the port version number is not displayed in the menu temporarily.
tablet PC
It is indicated in iPad Air 5 specification parametersUSB-CSupport 10Gbps interface speed, maximum support6K@60HzVideo output specification;Conduct video output measurement, and the screen resolution is4K@60HzHowever, due to the screen scale, there will be large black edges on the left and right, which will affect the appearance.
mobile phone
In addition to laptops and tablets, some mobile phones also support line to line video transmission. A C2C cable supporting video transmission is used to connect Huawei mobile phoneschargeConnector andUSB-CInterface, you can project the mobile phone to the display.
Switch
Users who have used the projector to play games know that playing games on a large screen is really enjoyable.
Although at 1080P resolution, the picture quality must be better than the 720p screen on the switch, and the operation delay is almost imperceptible.
Support fast charging
Unexpectedly, now the display has started to "roll" fast charge, but the display supports fast charge is what I hope to see, which is good for ordinary users.Let's take a look at the interface configuration at the bottom of the displayUSB-CInterface is an interface that supports fast charging.
Measured millet displayUSB-CThe port only supports the PD 3.0 fast charging protocol, and the fast charging power is 65W.
Read the PDO gear, which supports 5-20V full voltage gear, and the maximum power is 20V 3.25A 65W.
useUSB-CIt charges the iPad Air 5 with a power of 15.02V 2.01A 30.14W. The output power of the USB-C port can fully meet the fast charging requirements of the iPad Air 5.
Charging the laptop, the measured output power of the USB-C port was 19.55V 3.23A 63.17W, basically meeting the maximum output power of the USB-C port.
It charges the Red Devil 7 Pro with a power of 8.81V 2.88A 25.36W. The USB-C port can also charge the mobile phone quickly.
In addition, the USB-A interface of the monitor also supports charging, but it is not about fast charging. It is mainly to connect devices such as keyboard and mouse, and release the expansion space of the host or notebook.
Summary
According to the actual measurement, the USB-C port equipped with this Redmi display supports 65W fast charging, which is rare in the current display terminal. The 65W fast charging power has reached the practical level, which can meet the fast charging requirements of mobile phones, tablets and even laptops. It is indeed a correct functional configuration.
data transmission
According to the actual measurement, the USB-C port of the display also supports data transmission. In the figure above, the mobile phone is connected to the USB-C port on the back of the display, and the Xiaomi 11 Pro mobile phone is successfully read on the computer end.
In fact, not only mobile phones, but also storage devices such as USB flash drives and hard disks can be connected to computers through the USB port of the monitor. This expands the connection interface as well as the large screen.
Because more and more notebooks are developing in the direction of thin and light, it is normal for them to have rich functions but a small number of interfaces. If you connect the monitor, you can also expand more interfaces. For example, if you need to use a camera to transfer pictures to the notebook, you can use it directly with the USB interface on the back of the display.
Visual function
In addition to the basic display functions, the display screen image quality is the most important purchase point.
In addition to the basic brightness and contrast, which can make the picture more bright, the signal response time, signal input modeAnti blue light, visual angle and other aspects are increasingly valued by users;So when we have to live and work with the monitor for a long time,Anti blue lightFunction has become one of the key elements.
This Redmi 4K 27 inch display has the dual low blue light certification of German Rhine T ∨ V and SGS, as well as the globalDCDimming technology and VESA DisplayHDR™ 400 certification, 1200:1 high contrast, 4K native image quality display;In addition, it has an ergonomic rotation, the official view angle of the screen can reach 178 °, and the IPS straight panel has no drag problem, which improves the comfort during use.
Summary of charging head network
The Redmi 4K 27 inch display supports multiple resolution adjustments, with the highest4K@60HzHigh definition resolution and 2A1C are configured with three USB ports in total. The appearance and bracket are measured to have ergonomic rotation characteristics, and the shell design with fine coating is adopted. The connection between the shell and the frame is equipped with "invisible" cooling holes for auxiliary heat dissipation.
Among them, the USB-C port supports up to 65W PD charging and video transmission are also the highlights of this display. Although it only supports the PD3.0 protocol, it is compatible with mainstream smart devices in the market, and charging compatibility is impeccable;In addition, all USB interfaces can support the data transmission function and integrate the "USB HUB" function when used as the display screen;It is measured that only one USB-C data cable is needed for mobile phones, laptops and even game consoles to expand while charging. No need to consider whether the host supports it or not. The integration with the device on hand is an independent portable workstation, which can free up clean creative space as much as possible.
For the most important image display quality, this display officially has a contrast of 1200:1, a brightness of 350cd/㎡ and a gray scale response time of 6ms. Turning on the low blue light mode can reduce blue light exposure without affecting color accuracy;In addition to the three-year quality guarantee and after-sales door-to-door service provided by Redmi, the current price of 1799 yuan for promotional activities is really impressive.
