Largest portable screen? ASUS ZenScreen MB249C out of the box

ASUS’s ZenScreen series has introduced several models, covering a wide range from IPS to OLED panels, and refresh rates from 60Hz to 144Hz. While these screens have typically been sized between 13-17 inches, similar to a standard laptop screen, the new ZenScreen MB249C breaks the mold with a 24-inch panel. Will this substantial increase in portable screen size deliver a uniquely different user experience?

The ZenScreen MB249C features a 23.8-inch 16:9 IPS panel with a 1920 x 1080 resolution, a refresh rate of 75Hz, and Adaptive-Sync variable refresh rate technology. It also includes a low blue light mode and flicker-free technology for comfortable viewing. The monitor also comes with dual 1W speakers and supports picture input via USB Type-C and HDMI, with the Type-C port additionally supporting 60W PD charging.

ASUS has equipped the ZenScreen MB249C with three different stand modes for varying use cases. The screen’s rear folding bracket offers a step-less 150-degree adjustment, providing a viewing angle range of 12-60 degrees. The C-clamp stand offers a tilt range of -5 to 20 degrees, a 180-degree left and right rotation, a 90-degree upright screen rotation, and height adjustment. Finally, there’s the partition hook kit that can be hung on common office partition boards, offering up to 150mm of multi-stage height adjustment.

The ASUS ZenScreen MB249C is designed with a three-sided narrow bezel to maximize the display area, ensuring an immersive visual experience. Its anti-glare panel efficiently prevents light reflection from disrupting the viewer’s experience. With an IPS panel providing a 178-degree viewing angle, this portable screen is suitable for group viewing, allowing multiple people to share content comfortably.

Adding to its aesthetic appeal, the back of the monitor features a subtle texture that not only enhances the tactile feel but also helps prevent fingerprints. The built-in folding stand makes it easy to set up the screen wherever needed and can also function as a handle for transport. Additionally, a C-shaped stand buckle is incorporated in the middle of the monitor, and it includes a 100x100mm VESA mount compatibility, allowing it to be attached to any universal monitor stand.

Flexible Placement | ASUS ZenScreen MB249C Three Standing Modes for You to Choose

The ASUS ZenScreen MB249C offers three different standing modes for flexible positioning. In addition to the built-in folding stand that was showcased in the unboxing, there are also C-shaped stand supports and partition mounts provided.

The C-shaped stand needs to be clamped onto the table and is compatible with surfaces up to 15cm thick, making it suitable even for more substantial tables such as those made from angle steel. The bracket and screen are affixed using a quick-release mechanism. During installation, the screen just needs to be placed on the corresponding bracket position to secure it. To remove it, simply press the buttons on either side while lifting the screen. This intuitive design makes it very user-friendly.

The stand allows for a broad range of motion, including vertical and horizontal movement, tilt, and rotation. The adjustable range is highly extensive, offering excellent flexibility. The stability and damping mechanisms during adjustment are also superb, contributing to an easy and smooth user experience.

The partition wall mode is designed for typical office partitions, compatible with those between 2-4cm thick. This mode gives an effect similar to wall mounting. It allows for approximately 15cm of height adjustment, offering flexibility in screen placement. The installation is quite simple: the screen’s folding bracket can be hung directly onto the partition. This mode can significantly save desktop space, though it does not provide adjustments like tilt and rotation.

If you were to evaluate the ASUS ZenScreen MB249C using the criteria for a 15.6-inch portable screen, you might find the product a bit odd. It’s not compact enough to fit in a backpack, and it requires an external transformer. However, ASUS has provided three different stands for this screen, emphasizing its versatility to move around office spaces.

You could install the C-clamp bracket or hook kit at your desk. When needed for screen sharing with colleagues or clients, you can take it to meeting rooms. Compared to relocating a standard 24-inch monitor, this product is far more convenient. It’s also suitable for those working from home who desire the flexibility to change their workspace, such as moving between the living room, dining table, or kitchen.

In terms of screen quality, the ASUS ZenScreen MB249C is quite impressive. It performs well in routine office tasks, web browsing, or streaming YouTube videos. The Type-C connectivity to a laptop is a very convenient feature. However, it’s unfortunate that it cannot be powered like a typical 15.6-inch portable screen with a pen. It requires an external DC transformer, meaning you’ll need to carry it wherever you use the screen. If it could be powered by a built-in battery or Type-C, it would offer even more convenience.

When tested for color performance using SPYDER X ELITE, the ASUS ZenScreen MB249C achieved 98% of the sRGB color gamut, and the average color accuracy reached 0.6 – both of which are quite commendable results. This indicates that the screen provides highly accurate color representation, essential for tasks requiring precise color matching.

Priced at 9900 yuan, the ASUS ZenScreen MB249C might seem steep for a 24-inch 1080P display. However, for a portable monitor, especially one that includes a versatile C-clamp bracket, it is quite reasonable. The superior texture and quality of the screen case stand out compared to standard monitors, adding to its value.

There are several types of users for whom this monitor could be a worthy investment. First, those who require an external monitor for their laptop may find the MB249C particularly useful since monitors supporting Type-C input are often pricy. Furthermore, the flexible stand of the MB249C is more versatile than what’s offered with typical 24-inch monitors.

Secondly, individuals who use their computers in varying locations, but primarily indoors, may find this monitor helpful. Examples could include those without a dedicated desk at home or those who frequently move between office spaces or need to showcase visuals to a group. The potential uses for this screen are diverse, limited only by the creativity of the users.
