Unboxing the ASUS ZenScreen Duo OLED MQ149CD
The ASUS ZenScreen Duo OLED MQ149CD comes in an interesting package that’s made of two boxes. A large box crafted from sturdy brown cardboard holds within a smaller and much more elegant gray box, together with a tripod socket kit, a power adapter, a microfiber cloth, and a ZenScreen sleeve.

Inside the second box, everything is neatly arranged. The monitor is cushioned with foam padding and wrapped in a soft plastic sleeve. In addition to the ZenScreen Duo OLED MQ149CD itself, the box includes a series of accessories that differ depending on the region you live in. Besides the three elements I’ve already mentioned in the previous paragraph, the package includes two USB Type-C cables, a mini HDMI to HDMI cable, a microfiber cloth, and a quick setup guide, plus a warranty card.

Unboxing the ASUS ZenScreen Duo OLED MQ149CD is a pleasant experience, as the number of accessories you get is generous and the attention to detail is evident. I especially appreciated the inclusion of both USB and HDMI cables, as that ensures instant compatibility with a wide range of laptops and devices without the need for additional adapters.
Design and hardware specs
Opening up the ASUS ZenScreen Duo OLED MQ149CD feels much like opening a laptop, but instead of a keyboard and screen, you have two connected OLED panels. Each has a 14-inch diagonal size and a resolution of 1920 x 1200 pixels in a 16:10 aspect ratio. Together, they create a combined 21-inch workspace that measures 31.9 x 21.2 x 1.5 cm (12.56" x 8.35" x 0.59"). Worth noting, it weighs approximately 1.07 kg (2.36 lbs), making it highly portable for a dual-screen solution.
The displays have a resolution of 1920 x 1200 pixels
Both screens have a standard refresh rate of 60 Hz, generous viewing angles (176° both horizontally and vertically), a typical contrast ratio of 100,000:1, and a maximum typical brightness of 400 cd/m2. They also support Display HDR 400, and when HDR is on, the contrast ratio and brightness go up to a maximum of 100,000,000:1 and 500 cd/m2, respectively.
The ASUS ZenScreen Duo OLED MQ149C also supports HDR
Oh, and the monitor also offers high color accuracy, with both displays covering 100% of the DCI-P3 color gamut. You’ll find this particularly useful when editing photos, as the colors appear true to life without the need for constant color calibration.
The foldable monitor is powered via USB Type-C and can connect to laptops or other devices using USB Type-C or HDMI. If you’re using USB-C for linking the monitor’s screens to your laptop, the ZenScreen Duo can draw power directly from your other device. If, on the other hand, you connect the monitor using its HDMI port, you need to also attach the power adapter to the top USB-C port to give it the power it needs. Worth noting, all the ports and buttons are found on the right edge of the bottom screen, which helps keep the top panel slim and unobstructed.

Moreover, a neat feature of this foldable monitor is that you can also configure each OLED screen independently. While both can mirror or extend your laptop’s display, you can also have them function separately by connecting one screen to one device and the other to a different laptop or PC. For example, you could work on one screen, connect to your laptop, and have your child watch a movie on the second one, mirrored from their smartphone or another device. That is, of course, if the phone supports USB-C video output (DisplayPort Alt Mode). For instance, I know that the Samsung Galaxy S series, as well as some Motorola and ASUS smartphones do.
You can use each screen with a different computer
The monitor’s design also includes some other neat features, like a 360° hinge, a built-in kickstand, and a standard tripod mount. What all this means is that you get more than just a few different options to position and use this dual-screen monitor.
The hinges allow for 360 degrees rotation
The ASUS ZenScreen Duo OLED MQ149CD has a typical power consumption of 13 Watts. In power-saving mode, it should draw less than 0.5 Watts, and when it’s off, it requires less than 0.3 Watts.

Using the ASUS ZenScreen Duo OLED MQ149CD
The first thing I noticed when I began using the ASUS ZenScreen Duo OLED MQ149CD was its quality: it feels premium in all regards. Once connected to my laptop via USB Type-C, it came to life without requiring any special drivers.

I also briefly tested it with a desktop computer using its HDMI port, and the setup process was just as easy. This only proves how quickly you can move the monitor from one device to the other. You can take it with you while traveling and connect it to a laptop, and have it immediately ready on your desk at home, connected to your main PC.
The built-in kickstand proved stable, and so did positioning the monitor in tent mode. The latter isn’t something I aimed for, as I work from home, but I can see how it could be useful when you want to run a presentation in an office, for instance.

When it comes to actual performance, meaning image quality mainly, the dual 14-inch OLED panels were nothing short of extraordinary. The deep blacks and vibrant colors immediately catch your eye, and I must admit that the extra screen real estate made my day-to-day tasks significantly more efficient. I enjoyed keeping my writing environment on one screen while using the additional screens to research, chat on Discord, or simply skip tracks in my YouTube Music playlists.

Overall, my experience with the ASUS ZenScreen Duo OLED MQ149CD was overwhelmingly positive. It combines portability with superb image quality into one compelling package.
