ASUS ZenScreen MB16AC Review: Portable Dual-Screen Setup for Cape Town

What It Is and Who It’s For

The ASUS ZenScreen MB16AC is a 15.6-inch portable monitor that connects to your laptop via a single USB-C cable. No external power brick, no HDMI adapter, no fumbling with multiple cables at a cafe table. One cable handles both the display signal and power.

It’s built for people who need a second screen but don’t want to be chained to a desk. If you’re working from coworking spaces around Cape Town, splitting time between your apartment in Green Point and a cafe in Woodstock, or just tired of alt-tabbing between Slack and your actual work, this is the category of product you should be looking at.

The ZenScreen has been around for a few years now, which means ASUS has had time to iron out early firmware issues. It also means you can sometimes find it discounted. In South Africa, expect to pay between R6,500 and R8,500 depending on the retailer and whether stock is available locally or imported.

What We Tested

We used the ZenScreen across multiple Cape Town locations over three weeks:

Workshop 17 (V&A Waterfront): The hot desks here give you a reasonable amount of space, but not unlimited room. We set up the ZenScreen alongside a 14-inch MacBook Pro to test dual-screen productivity in a coworking environment. The desk space accommodated both screens comfortably, though you’ll want to angle the portable monitor slightly to avoid glare from the overhead lighting.

Truth Coffee Roasting (Buitenkant Street): Cafe desks are a different story. The tables at Truth are not designed for dual-monitor setups. We managed it, but the ZenScreen’s foldable cover-stand doesn’t grip surfaces well when space is tight and someone bumps the table reaching for their flat white.

Apartment setup (Green Point): Used as a semi-permanent second screen on a small desk. This is honestly where the ZenScreen performed best — stable surface, controlled lighting, no one jostling your setup.

Outdoor test (Bree Street balcony, midday): We wanted to see how the screen handled Cape Town’s harsh summer light. Short answer: not well, but that’s true of every portable monitor in this price range.

What’s Good

Single-cable simplicity works. Plug in one USB-C cable and the screen powers up. On a MacBook Pro with Thunderbolt, the connection was instant and stable. No driver installation needed on macOS. Windows required a quick driver download the first time, then worked without issues.

The weight is right for daily carry. At 780g, the ZenScreen adds less than a kilogram to your backpack. That matters when you’re walking from your apartment to a coworking space or catching a MyCiTi bus. The included smart cover adds some protection without significant bulk.

IPS colour accuracy is solid for work. If you’re doing design work, the 100% sRGB coverage means colours are reliable enough for web design, photo editing, and content creation. It’s not a colour-critical monitor for print work, but for the tasks most remote workers handle, it’s more than adequate.

Auto-rotate is useful. Turn the monitor to portrait mode and it detects the orientation change automatically. This is excellent for reading long documents, reviewing code, or keeping a Slack channel visible while working on your main screen.

The foldable cover doubles as a stand. No separate stand to carry or lose. The cover folds into a wedge that props the monitor at a usable angle. It’s not adjustable — you get one angle — but it works for most desk heights.

What’s Not

220 nits is not enough for bright environments. This is the ZenScreen’s biggest limitation for Cape Town use. At Workshop 17’s interior desks, the brightness was fine. At a window seat or anywhere with direct light? You’re squinting. Forget about using this on a balcony or outdoors during the day. The screen washes out completely in direct sunlight.

The foldable stand is flimsy. It works on a stable desk, but on uneven cafe tables or surfaces with any vibration, the monitor wobbles. At Truth Coffee, a barista walking past caused enough table vibration to make the screen shift. You learn to position it carefully, but it’s a known weakness.

Power draw from your laptop battery is noticeable. The ZenScreen pulls about 8-9 watts from your laptop via USB-C. On a MacBook Pro 14-inch, that translated to roughly 1.5 to 2 hours less battery life compared to running the laptop screen alone. In a city where load shedding can knock out cafe power unexpectedly, that’s worth factoring in. You’re trading battery life for screen space.

No USB-C passthrough charging. You can’t daisy-chain a charger through the monitor. This means if your laptop only has two USB-C ports and one is powering the ZenScreen, you’re down to a single port for charging and everything else. Dongle life begins.

Availability in South Africa is inconsistent. ASUS products come and go from local retailers. Takealot occasionally stocks it, but often it’s out of stock and you’re looking at importing from Amazon or finding a local importer. That pushes the price up and adds delivery time.

How It Compares

Against the Lenovo ThinkVision M14 (14 inches, ~R5,500-R7,000): The Lenovo is lighter and slightly cheaper, with USB-C passthrough charging — a real advantage. But the screen is 1.6 inches smaller and 300 nits versus the ASUS’s 220 nits (Lenovo wins on brightness). If portability matters most, the Lenovo edges ahead.

Against the ViewSonic VG1655 (~R4,500-R5,500): The ViewSonic is the budget pick and more readily available on Takealot. Build quality doesn’t match the ASUS, but it offers similar specs at a lower price and includes a mini-HDMI port as a backup connection option.

The Verdict

The ASUS ZenScreen MB16AC is a competent portable monitor that does what it promises: give you a second screen without much hassle. The single-cable USB-C connection is reliable, the weight is manageable for daily carry, and the display quality is good enough for professional work.

But in Cape Town specifically, the 220-nit brightness is a real constraint. If you’re mostly working in interior coworking spaces with controlled lighting, it’s fine. If you’re the type who gravitates toward window seats, outdoor terraces, or bright cafes, you’ll struggle with screen visibility for portions of the day.

The battery drain is the other consideration. Cape Town’s load shedding situation has improved, but it hasn’t disappeared. An extra monitor pulling 8-9 watts from your laptop means less runtime when the power goes out. Carry your charger and a power bank.

If you can find it at a reasonable price locally and your primary use is indoor coworking, the ZenScreen is a reliable choice. If you need brightness or passthrough charging, look at the Lenovo ThinkVision M14 instead.
