HKMLC 55-inch Smart Whiteboard In-Depth Review: A Powerful Assistant for Education and Business Scenarios

At a time when digital office and education are constantly innovating, the importance of smart interactive devices is becoming increasingly prominent. Today, we will take a deep look at a highly anticipated product, the HKMLC 55-inch smart whiteboard, to see how it can play a unique role in business meetings and educational teaching scenarios.

Design and Build Quality

This smart whiteboard looks somewhat similar to an ordinary 55-inch TV, but in fact, its functions are quite different. It has a 4K display with a resolution of up to 3840×2160, 400nits of brightness, and 170° vertical and horizontal viewing angles, ensuring clear visual effects whether in a bright classroom or a conference room with complex lighting. Its all-metal body design is not only sturdy and durable, but also adds a sense of texture. However, it is also relatively heavy, about 55 pounds, and it is best to be unpacked by two people. In terms of installation, users can choose to buy a separate metal bracket, which is very sturdy and has rollers, making it easy to move and adjust the position in different scenarios; or use the included wall-mounted accessories to fix it on the wall, which can flexibly meet various space layout requirements.

Interface Configuration

In terms of interface configuration, the HKMLC 55-inch smart whiteboard is very rich. The back of the fuselage is equipped with audio input, VGA input, two HDMI interfaces, USB Touch Port for touch screen, USB 3.0, USB 2.0 ports, TF card reader, and Wi-Fi antenna connector. There are power plugs, power switches, RS232 ports, audio output ports, digital coaxial ports, and Ethernet ports on the side of the fuselage. The front is equipped with a power button, USB C port, HDMI port, another USB Touch Port, and two USB 3.0 A ports. Such a variety of interfaces make it easy to connect various external devices, such as computers, projectors, speakers, storage devices, etc., fully meeting the needs of different users in different scenarios.

Android System and Customization

The HKMLC smart whiteboard has a built-in Android system, which gives it powerful functional extensibility. The main interface is simple and intuitive, integrating time, date display, and device connection information. Users can also personalize the interface according to their own preferences, such as changing wallpapers. They can choose from a variety of themes that come with the system, upload custom images from local files, and even set up automatic looping wallpaper switching. In terms of sound settings, not only can the volume of the built-in 15W speaker be adjusted and the left and right channels balanced, but also multiple sound modes such as standard, conference room, theater, classroom, and custom are provided to meet the auditory needs in different usage scenarios.

Special Features: The "Compass"

Speaking of special features, its "compass" function has to be mentioned. Users only need to press the screen with five fingers to evoke this convenient navigation bar. The "compass" includes common buttons such as return and home page, and can also display all currently running applications, and the entire interface elements support customization. For example, users can set the "compass" to automatically fold according to their own operating habits, and automatically retract after 5 seconds to avoid blocking the screen content; they can also fix it at any position on the screen for easy operation at any time. In addition, you can lock and wake up the screen by double-clicking the screen with two fingers, and record the screen by sliding down with three fingers (this function may vary on some models due to different configurations). These gesture operations greatly improve the convenience of use.

Whiteboard Application

One of the core functions of the smart whiteboard is its powerful whiteboard application. In whiteboard mode, users can use their fingers or the matching pen to write and draw. You can easily switch to the eraser function with the back of your hand or the top of your palm. The system will intelligently determine whether it is a writing or erasing operation based on the contact with the screen. Moreover, the whiteboard supports 20-point touch, and multiple people can operate on it at the same time to achieve efficient interactive collaboration.

Writing and Drawing Tools

During the writing process, users can not only freely choose the color of the pen and adjust the thickness of the pen, but also use various practical tools. For example, clicking a specific button on the pen can automatically convert handwritten scribbled text into neat text. When drawing a shape, even if the drawing is not very standard, the system can automatically recognize and correct it to a perfect shape, such as a circle, square, triangle, etc. In addition, users can also add a variety of preset shapes, select, move, scale, copy, delete and other operations on the drawn graphics, and insert auxiliary tools such as pictures, grids, rulers, protractors, etc., to facilitate accurate drawing and measurement. These functions are particularly useful in teaching and demonstration scenarios.

Interactive Functions

What is more worth mentioning is that this smart whiteboard also has interactive functions. Through the eshare application installed on the mobile phone, users can mirror the mobile phone screen to the whiteboard to achieve two-way interaction. During the meeting or teaching process, participants can operate on their mobile phones, and the content is synchronized to the whiteboard in real time, which greatly improves the interactivity and participation. At the same time, the whiteboard also supports multi-person split-screen collaboration. By clicking the split-screen button on the whiteboard, the whiteboard can be divided into multiple areas. Different people can operate in their respective areas without interfering with each other, which is convenient for group discussion and cooperative presentation.

Additional Features

In addition to the above functions, the HKMLC 55-inch smart whiteboard also has some practical additional functions. For example, it has a voting function. Teachers or meeting organizers can create voting topics and options on the whiteboard. Students or participants can vote on their mobile phones by scanning QR codes. After the voting, they can see the voting results immediately. This is very practical in scenarios such as classroom quizzes and meeting decisions. In addition, the whiteboard supports screen recording. Users can choose 720p or 1080p resolution, record media sound, microphone sound, or both at the same time, which is convenient for recording important meeting content or teaching process.

Conclusion

The HKMLC 55-inch smart whiteboard is very rich in functions. Whether it is data display and interactive discussion in business meetings, or knowledge explanation and classroom interaction in education and teaching, it can provide efficient and convenient solutions. Of course, some minor problems were found during use, such as the eraser function was not very sensitive in some cases, but this did not affect its overall excellent performance. I look forward to further exploring its potential in subsequent use, and I also hope that manufacturers can continuously optimize products to bring users a better experience.
