Asus ZenScreen MB166CR Portable Monitor: The Ultimate Companion for On-the-Go Professionals
As someone who is constantly moving, I always look for accessories and tools that help me work better, faster, and smarter. My goal is to simplify and enhance my daily life. I had been considering a portable monitor for quite some time. Still, it would allow me to work from anywhere without compromising my productivity as a content creator.

Portable monitors are widely available, but only some come with a built-in kickstand. Most rely on their covers as stands, which may not offer the flexibility to tilt to the preferred angle. After researching reputable brands like Asus, AOC, Viewsonic, and Prism, I discovered the ASUS ZenScreen MB166CR portable monitor. This portable monitor promised to meet all my needs and fit within my budget as a secondary screen. It is also an excellent companion for travelling designers, programmers, and office creatives alike.

Pros and Cons of Using the Asus Zenscreen MB166CR
Having used the ASUS ZenScreen MB166CR portable monitor for two weeks, I have gathered some clear insights into its strengths and weaknesses.
- Portability: The lightweight and slim design has made it incredibly easy to carry around. The monitor fits perfectly in my laptop bag without adding significant weight, making it convenient for my on-the-go lifestyle.
- Connectivity: The USB-C connectivity has been a major plus. It allows me to connect the monitor to my laptop, tablet, and mobile phone with a single cable, reducing clutter and simplifying the setup process.
- Screen Quality: The 15.6-inch Full HD IPS display offers adequate colour accuracy and wide viewing angles. This has been particularly beneficial for my editorial work and video editing.
- Ease of Use: The plug-and-play functionality means I can quickly set up the monitor without hassle. The foldable smart case that doubles as a stand has been very handy, allowing me to position the monitor at comfortable angles for different tasks.
- Anti-Glare Screen: The anti-glare coating on the screen has reduced reflections, making it easier to work in various lighting conditions, from bright offices to dimly lit rooms.
- Brightness Levels: While the screen quality is generally good, the brightness levels could be higher. In very bright environments, I occasionally find it difficult to see the display clearly.
- Lack of Built-in Speakers: The absence of built-in speakers is a drawback, especially when I’m using the monitor for entertainment purposes. I’ve had to rely on external speakers or headphones for audio, which adds to the setup.
- Power Consumption: Although the USB-C power delivery is convenient, I’ve noticed that the monitor drains my laptop’s battery faster when it’s connected. This requires me to be more mindful of battery usage during extended work sessions without access to power outlets.
- Stand Stability: The kickstand, while useful, doesn’t provide the most stable support. On uneven surfaces, the monitor can be a bit wobbly, which can be distracting during intensive tasks.

Criteria for Choosing a Portable Monitor as a Secondary Monitor
Since this is my first time purchasing a portable monitor, it's crucial to identify the key requirements to make the right choice. Here's what I need to consider:

Connectivity
Versatile connectivity is a must. A monitor with USB-C is ideal because it can handle power, video, and data transfer through a single cable. This simplifies connections and minimizes cable clutter. Additionally, having an HDMI port would be beneficial for broader compatibility with other devices like tablets and mobile phones. It's also useful to ensure the monitor supports multiple operating systems (Windows, macOS, Android, iOS).
Power Source
For convenience, the portable monitor should be able to draw power directly from my laptop or other devices via USB-C. This eliminates the need for extra power adapters and simplifies the setup. However, it's also good to have the option for external power if needed.
Portability Features
Since I'm always on the go, the monitor must be lightweight and slim. A foldable smart case that doubles as a stand would be very useful, providing protection during transport and making it easy to set up the monitor in various environments.
Screen Quality
An anti-glare or matte finish is important to ensure the monitor is usable in different lighting conditions. This reduces reflections and eye strain. High brightness levels (above 250 nits) are preferable for better visibility.
Refresh Rate
A refresh rate of at least 60Hz is necessary for smooth performance during editorial work and video editing. While higher refresh rates are better for gaming, 60Hz is sufficient for my primary tasks.
Built-in Features
Built-in speakers are a bonus, although I prefer external speakers or headphones for better sound quality for video editing and entertainment. A touchscreen feature might also be beneficial, particularly if I plan to use the monitor with tablets or mobile devices.
Durability
The monitor should have a robust build quality to withstand frequent travel. A protective case or cover is essential to prevent damage during transport.
Price
Finally, I need to consider the cost. While high-end models with additional features and 4K resolution can be more expensive, balancing my budget with the features I need is important. Typically, a good portable monitor ranges from $150 to $400.
By carefully considering these criteria, I can ensure that I choose a portable monitor that will significantly enhance my productivity and enjoyment while on the move. The key is to find a balance between size, resolution, connectivity, and portability to suit my specific needs for editorial work, video editing, and entertainment.

Its USB-C connectivity allows seamless use across my laptop, tablet, and mobile phone with a single cable, simplifying my setup and minimizing clutter.
The monitor's lightweight and slim design, coupled with a foldable smart case that acts as a stand, enhances its portability and ease of use in various environments. While it lacks built-in speakers, this is a minor drawback compared to the overall benefits. Given these features and its reasonable price point, the ASUS ZenScreen MB166CR portable monitor which is just over two hundred dollars, seems worth the investment to boost my productivity and enjoyment on the go.

This portable monitor offers incredible value at its price point. While it may not have the brightest screen, the highest colour accuracy, or the most luxurious design, it excels in many practical aspects.
It's not ticking any of the ‘best of' boxes but marks many of the ‘good enough' boxes. The ASUS ZenScreen MB166CR portable monitor is a solid device that costs two hundred-ish dollars compared to other portable monitors in the same class, easily costing upwards of three hundred dollars.

Design and Portability
Lightweight and Compact Design
The ASUS ZenScreen MB166CR portable monitor is incredibly lightweight, weighing only 780 grams, and boasts a thin profile with slim bezels. Its compact size makes it easy to carry around, fitting comfortably in a laptop bag without adding much bulk.

Build Quality
The build quality of the ASUS ZenScreen MB166CR portable monitor is robust and durable, making it well-suited for frequent travel. Its lightweight design combined with a protective smart case ensures that it can withstand the rigours of on-the-go use.

Built-in 360° Kickstand

My favourite features are the single USB-C cable operation and the built-in 360° kickstand. This Kickstand allows me to position the monitor in either landscape or portrait mode, providing flexibility depending on my workspace and the tasks at hand.
Display Quality
Full HD IPS Display
The 15.6-inch Full HD (1920 x 1080 with an aspect ratio of 16:9 at 60Hz refresh rate) IPS display offers decent brightness at 250cd/m2 and a 262K colour display with a response time of 5ms (GTG). It is flicker-free, which significantly reduces eye fatigue during long working hours. Including a blue light filter further protects the eyes, especially when working at night.

While it may not be the brightest or most colour-accurate screen, it is sufficient for general productivity tasks. It is bright enough to view outdoors. It has decent coverage of the sRGB spectrum, so colour accuracy is acceptable. The colour shifts slightly at extreme viewing angles, but overall, the display quality is satisfactory for document editing, web browsing, multimedia editing, and consumption. Having acceptable colour accuracy on the display is important because you want what you edit on your screen to look similar to what you post online.
Connectivity and Usability
Single USB-C Connection
One of the major advantages of the ASUS ZenScreen MB166CR portable monitor is the single USB-C connection for both power and video. This reduces cable clutter and makes the setup process incredibly straightforward. The monitor draws power directly from the connected device, which is efficient and convenient, especially when working remotely.

Plug-and-Play Functionality
With its plug-and-play functionality, the ASUS ZenScreen MB166CR portable monitor is compatible with most laptops and tablets without additional drivers. This feature is particularly useful for on-the-go professionals who need a quick and hassle-free setup.
Asus ZenScreen MB166CR Practical Use Cases
Boosting Productivity
For most people who are going to be travelling and using a second monitor in a portable setting, immense colour accuracy isn't a priority. As I travel frequently for work, I hoped a second screen would give me the extra screen real estate to improve my workflow. I noticed a significant need for more productivity when travelling since I work on a 14-inch laptop screen.

With the extra “room,” I can craft a review on one screen and refer to my researched information on another. Or edit videos on one screen and view the output on another. Similarly, programmers can run applications on one screen and see code on the other, allowing for a more efficient workflow.
Versatile Setup
Lately, I've been super distracted while working at home and have been hanging out at coffee shops to get work done. As you know, when you're at coffee shops, you get those really small tables and can't have your laptop and additional screens beside you. Here's where another useful feature of this monitor shines:. It has a quarter-inch thread built right into the stand. I could mount the ASUS ZenScreen MB166CR portable monitor on my little tripod, so the monitor is on top, and my laptop is on the bottom. This is a more ergonomic setup, and it is more natural to have the screen extend upwards rather than sideways.

Client Meetings
When meeting clients, I can easily share the second screen so they don't have to feel uncomfortable peering over my shoulder to see a small laptop screen. This makes presentations and collaborative work sessions more professional and efficient.
Leisure Use
When I return to the hotel, I use it for leisure to play with my Nintendo Switch. The portability and ease of setup make it a versatile companion for work and play. The screen is decent enough to support two players playing Smash Bros., making it a great addition to my travel gear.

Editor's Final Thoughts and Value Proposition on the Asus ZenScreen MB166CR Portable Monitor
After thoroughly testing the ASUS ZenScreen MB166CR, I found it an excellent choice for anyone needing a portable, affordable secondary monitor. While it may only be suitable for colour-critical tasks with additional calibration, its portability, ease of use, and eye care features make it ideal for writers, editors, and mobile professionals.

If you're looking for a lightweight monitor that enhances productivity on the go without breaking the bank, the ASUS ZenScreen MB166CR is a fantastic option. It has made my workflow smoother and more flexible, allowing me to work efficiently from anywhere.
