You might not think it to look at the Asus ZenScreen MB27ACF, but this 27-inch monitor is actually a portable display.
Now, we’ve reviewed plenty of the best portable monitors, but most clock in at around 14 to 16 inches – so this is a big jump.
It might be relatively light, all things considered, and it does have a built-in kickstand, but with a screen this size, this isn’t one for whipping out to work in the library or cafe, or playing games on a long flight. To my mind, this is a screen designed for businesses, collaboration, and a second screen for desktop set-ups, especially across multiple locations.
We’ve previously reviewed the 24-inch Asus ZenScreen MB249C portable monitor. It’s not dissimilar in design, but we found it had a few flaws – chiefly the low resolution (1080p) and pixel density (92.56 ppi), and the so-so built-in speaker, a perennial issue for portable displays. It seems Asus has sat up and taken notice. The new MB27ACF now boasts a 2.5K resolution that better suits the big-screen experience, a pixel density of 218 ppi, and vastly better speakers.
I took the Asus ZenScreen MB27ACF for a test drive for several weeks as a second screen hooked up to a 14in laptop, to see how it measures up against my favorite portable displays.

First impressions? This display is big. Far bigger than any portable monitor I’ve used in the past. At first glance, I seriously doubted the portability of this display.
In the box you’ll find the VESA-mountable display, of course, alongside a pretty hefty monitor arm, hanging hooks for attaching to whiteboards, HDMI and USB-C cables, and the power supply unit.
Despite my initial misgivings, drawing it from the box, I was pleasantly surprised with how easy it is to carry. Yes, it’s large and relatively heavy at 6.57 lbs before any stand is attached, though not ridiculously so. I wouldn’t like to cart this around on the commute every day, particularly since it lacks any protective covering or sleeve.
With that in mind, I maintain this is still best for multiple set-ups across a single location.
Asus ZenScreen MB27ACF: Design & operation
Image 1 of 4
Given its size, to look at the MB27ACF, you’d be forgiven for thinking this is just an ordinary computer monitor. The screen is broad, the bezels are fairly slim, except along the bottom of the frame where you’ll find the speakers – a 2.1-channel audio with subwoofer that’s acceptable in use.
It’s only when you spin the monitor around that it gives itself away as a portable device. Around the back is a fold-out silver kickstand that pulls out and downward, which helps support the weight compared to those that just flip out from the bottom. Asus is billing this as a carry handle, but I wouldn’t chance it.
Initially, I found folding out this stand was a bit stiff, and I’d advise using a hand on either side to pull it into position, because it does feel like one hard yank might snap it. Once out, you can set it to multiple positions depending on desk-space and required viewing angle. At the center of the rear is a socket for attaching the C-clamp monitor arm, too.
Along the left side is the power jack, alongside three ports – a HDMI, USB-C, and audio jack. On the right is the menu, arrow keys, and power buttons. As such, operation is very straightforward. That USB-C port also offers 70W power delivery, letting you charge your laptop via the monitor, which is useful if you’re short on power sockets – the monitor already uses one, and there’s no built-in battery to help keep down the weight.
Asus ZenScreen MB27ACF: In use

Throughout testing, I had no trouble using this transportable monitor. It does everything I needed it to do without any fuss or issues, no dead pixels, problems seeing what’s on the screen. Yes, it is heavy. So, as a fully portable monitor, it’s not ideal. That’s not what it’s designed for, of course.
Surprisingly, the speakers were… acceptable. You’re never going to get high-end audio from a device like this, however, the sounds here are a lot less tinny than on many of the speakers on portable monitors. Saying that, I’d still recommend making use of the display’s 3.5mm audio jack or external speakers for tasks that demand the best audio experience.
Outside of that kickstand, which I would’ve liked to see somewhat reinforced, my only real issue is I didn’t find the screen especially bright. The display has a matte covering, which does a great job of limiting screen glare and reflections, but I’d hesitate to use this in direct sunlight.
I would’ve loved this to have a wider color gamut, too. 100% sRGB is fine for creating online assets. But now imagine if this packed 100% P3, or even AdobeRGB – it would make it a very attractive choice for mobile photographers, video editors, and all-round creators who want to conduct detailed creative work. And, wishful thinking though it may be, i can’t help feeling it’s a missed opportunity.
Realistically, though, that’s not who this monitor is for. It’s for business professionals in a collaborative office, and those who want a second screen on their desk that can be easily stashed away when not in use. On that score, the Asus ZenScreen MB27ACF delivers the goods.
Should I buy the Asus ZenScreen MB27ACF?
Buy it if…
✅ You want a big, portable display: With its 27in screen, this is a great choice for those who want a large screen with a high resolution for detailed work, and to supplement your laptop or computer screen.
✅ You’re collaborating with others: For my money, this display is best-suited for businesses who need to collaborate with colleagues or present to the wider team.
Don’t buy it if…
❌ You want ultra portability: Ok, it might be thin, light, and transportable, but the size and weight limit its portability – I’d suggest only moving this around multiple spaces in a single location, like an office.
❌ You’re a content creator: At just 100% sRGB, this monitor lacks a wide color gamut demanded by creative professionals like photographers.
