ASUS ZenScreen MB249C 23.8" Black 2023

The ASUS ZenScreen MB249C is a 23.8-inch portable monitor with a clever multi-mount design and USB-C connectivity, but the display itself is pretty basic. It's great for remote workers who need a full-size second screen in multiple locations, especially at the low end of the USD 230 to USD 360 price range. The kickstand has a documented design flaw, and the 250-nit panel with mediocre color performance means this is strictly a productivity tool. If you can grab it for around USD 230, it's a solid buy for the right use case.

Let's talk about what this panel actually does. The 23.8-inch IPS screen runs at 1920 x 1080 with a 75Hz refresh rate and a 5ms response time. That 75Hz is a small but real upgrade over the standard 60Hz you get on most office monitors, and it makes scrolling and window dragging feel just a touch smoother. The 5ms response time is fine for productivity work, though anyone hoping to game on this thing should temper expectations. Adaptive-Sync is there, which helps if you're running it off a laptop with a discrete GPU, but this is not a gaming monitor and the performance percentile ranking of 44th reflects that.

The brightness is 250 nits, which is adequate for indoor use but starts to struggle near bright windows or outdoors. The color story is similarly modest: 16.7 million colors on an 8-bit panel, which puts it in the 17th percentile for color performance in our database. That's not a typo. This is a monitor built for text and productivity, not photo editing or video work. The contrast ratio is 1000:1, which is standard for IPS panels and helps keep text readable. If you're coming from a laptop screen, this will feel like a lateral move in quality but a big upgrade in size.

The MB249C doesn't really compete with the monitors in our top competitor list, and that's worth being honest about. The MSI MAG 271QPX, LG UltraGear 27GX790A-B, Samsung Odyssey G60SD, Gigabyte M Series OLED MO27U2 SA, and Alienware AW2725D are all high-refresh gaming displays with OLED or QD-OLED panels. They're in a completely different league for color, contrast, and speed. If you're buying a monitor for gaming or content creation, those are the ones to look at. The MB249C is not trying to win that fight.

Where the MB249C actually competes is against other portable monitors, and there the field is thinner. Most portable options are 15.6 inches or smaller, so the 23.8-inch size here is genuinely unique. The trade-off is weight and bulk: at 4.84 kg, this is not something you'll toss in a backpack without noticing. The C-clamp arm and partition hook are differentiators that most portable monitors simply don't offer. If you need a second screen that can live on a cubicle wall or clamp to a desk edge, this is one of very few options. If you just need a lightweight travel monitor for occasional use, a smaller and cheaper 15.6-inch panel might serve you better.

Pricing on the MB249C is all over the map, which is worth paying attention to. In the US, we're seeing listings from USD 230 to USD 360 across six vendors. That's a USD 130 spread for the exact same monitor, so shopping around matters more than usual here. The best deal we're seeing is at the low end of that range, and honestly, at USD 230 this thing makes a lot of sense. At USD 360, you're creeping into territory where you could buy a decent 27-inch 1440p desktop monitor and still have change left over.

In Canada, the spread is even wilder: CAD 409 to CAD 797 across three listings. That's a CAD 388 difference, which is frankly absurd. If you're buying in Canada, do not pay the high end of that range. The value proposition here is entirely dependent on getting a good price. This is a niche product with a specific use case, and paying premium pricing for it defeats the purpose. The sweet spot is when you can grab it at or near the bottom of the price range.

The ASUS ZenScreen MB249C is a weird one, and I mean that in the most interesting way. It's a 23.8-inch portable monitor, which sounds like an oxymoron. Most portable screens top out around 15 or 16 inches, but ASUS decided to stuff a full-size desktop panel into a package with a carrying handle and a kickstand. The pitch is simple: you get real desktop screen real estate at a coffee shop, in a hotel room, or at a hot-desking office where the provided monitor is older than your laptop. It's aimed squarely at remote workers and frequent travelers who are tired of squinting at tiny secondary displays.

What makes this thing genuinely interesting is the mounting system. You get a fold-out kickstand that doubles as a handle, a partition hook for cubicle walls, and a C-clamp arm that attaches to the edge of a desk. That's three different ways to set this up before you even touch the VESA mount. Most portable monitors give you a flimsy origami cover and call it a day. ASUS actually thought about how people work in different spaces, and that's refreshing.

But here's the catch: the display itself is pretty basic. 1080p at 75Hz on an IPS panel with 250 nits of brightness. That's fine for spreadsheets and email, but it's not going to win any awards for color accuracy or HDR performance. The user sentiment score sits at 75 out of 100, which is decent but not stellar, and there's a recurring complaint about the kickstand design that we'll dig into later. For the right person, this is a clever tool. For everyone else, it might be a compromise too far.

If you're buying a monitor for a permanent desk setup, skip this. A traditional 24-inch or 27-inch monitor at the same price will give you better brightness, better color, and a more stable stand without the portability compromises. The 250-nit panel and 17th percentile color performance are real limitations that will annoy you daily if you're not actually moving around. Look at a standard IPS desktop monitor instead, or step up to a 1440p panel if your budget allows.

Gamers and content creators should also look elsewhere. The 75Hz refresh rate and 5ms response time are fine for spreadsheets but not for fast-paced games, and the color accuracy is nowhere near what you'd want for photo or video editing. The monitors in our top competitor list, like the MSI MAG 271QPX or the Alienware AW2725D, are in a completely different performance class. If you need a portable gaming screen, there are smaller high-refresh options that will serve you better than this.

For the right person, the MB249C solves a real problem. If you're a remote worker who moves between home, office, and travel, and you need a full-size second screen without buying a monitor for every location, this is a compelling option. The USB-C single-cable setup is genuinely convenient, and the multiple mounting options mean you can adapt to whatever workspace you land in. The 75Hz refresh rate and IPS panel are perfectly adequate for productivity work, and the built-in speakers are a nice touch for video calls.

But this is not a monitor for everyone. If you care about color accuracy, brightness, or gaming performance, look elsewhere. The 250-nit panel will frustrate you in bright rooms, and the color performance is simply not competitive. The kickstand design flaw is also a real concern, especially since the kickstand is one of the headline features. If you're buying this, get it at the low end of the price range and consider whether the mounting flexibility justifies the compromises. For a stationary desk setup, a traditional monitor will give you more for your money.
