ASUS ZenScreen ASUS ZenScreen MB249C 23.8" Portable Monitor Review

The ASUS ZenScreen MB249C is a 24-inch portable monitor best described as 'relocatable.' It's heavy at over 10 pounds, but its killer feature is flexibility: it includes a kickstand, a carrying handle, and a full desk clamp arm. It's a niche solution for someone who needs one big screen to use in multiple fixed locations.

If you're hunting for a portable monitor that's actually portable, the ASUS ZenScreen MB249C is a bit of a curveball. It's a 23.8-inch, 1080p IPS screen with a built-in kickstand that doubles as a carrying handle, and it comes with a full C-clamp desk arm in the box. At around $300, it's pitching itself as a flexible, all-in-one second screen solution for office work or on-the-go productivity. The idea is solid: you get a monitor that can sit on a desk, clamp to a cubicle partition, or travel with you, all without needing a separate stand. But a 24-inch monitor that weighs over 10 pounds isn't exactly what most people think of as 'portable.' It's more of a 'relocatable' monitor for people who need a big secondary screen that's easy to move between a home office and a work desk, not something you'd casually toss in a backpack for a coffee shop session.

Performance-wise, this is a basic office monitor. The 75Hz refresh rate and 5ms response time are a slight step up from the standard 60Hz, which can make scrolling and cursor movement feel a tiny bit smoother, but it's not a gaming screen. In our database, its performance metrics land in the middle of the pack. The 250-nit brightness is just okay. It's fine for a well-lit office, but you'll struggle with glare in a bright room or near a window. Colors are decent for an 8-bit IPS panel, but it's not a display for color-critical work. The built-in speakers are there, but they're thin and tinny, just like on most monitors. For a portable screen focused on flexibility, the actual display quality is functional but unremarkable.

Priced between $290 and $350, the MB249C's value is all about the included flexibility. You're paying a premium over a basic 24-inch office monitor to get the kickstand, carrying handle, and full desk clamp arm in one package. If you need all those mounting options, it could save you money versus buying a monitor and separate arms. But if you just want a portable screen to use with a laptop, a lighter, slimmer 15-inch portable monitor around the same price might make more sense.

This monitor exists in a weird niche. Compared to true portable monitors like the 15-inch ASUS ZenScreen OLED or a Lepow portable display, the MB249C is huge and heavy. Those are meant for travel. This is meant for semi-permanent, flexible placement. Against standard 24-inch office monitors like the Dell S2421HN, the ASUS wins on included mounting options but loses on pure value and often has a weaker stand in desk-clamp mode. If your main need is a high-quality, adjustable second screen for a single desk, a good ergonomic monitor arm paired with a standard screen might be a better investment. The MB249C is for the person who needs one screen to serve in multiple physical locations with minimal setup.

Skip this if you want a monitor for gaming, media consumption, or color-accurate work. The 75Hz refresh rate isn't meant for serious gaming, and the 250-nit brightness isn't great for movies. Also, if true portability is your goal—like carrying it daily with a laptop—look at lighter 15-inch options. This thing is a tank. And if you just need a great second screen for one dedicated desk, a standard monitor with a good third-party arm is often a better value.

So, should you buy the ASUS ZenScreen MB249C? Only if its specific form of flexibility is exactly what you need. It's a great fit for someone who wants a single, large secondary monitor they can easily move between a home office setup (using the clamp) and a central office table (using the kickstand), or for mounting on a cubicle partition. It solves a specific logistical problem. For everyone else—especially anyone looking for a true travel companion for their laptop or a high-performance display—it's a hard sell. The weight and average screen quality hold it back from being a general recommendation.
