Let's be real—we've all been there. You're working from a cramped coffee shop, staring at your laptop's 13-inch screen, and wishing you had just a little more space to spread out your tabs. Or maybe you're traveling for a conference, and your hotel desk feels empty without that second screen you rely on at home. Enter the portable monitor: a gadget that's gone from "nice-to-have" to "absolute essential" for anyone who values productivity, creativity, or just a better viewing experience on the go.
Over the past few years, portable monitors have exploded in popularity, and it's easy to see why. They're lightweight, compact, and designed to slot seamlessly into our increasingly mobile lives. But with so many options flooding the market—from tiny 13-inch models to bulky 32-inch behemoths—it can be tough to know which one is right for you. That's why I've spent the past month testing some of the top contenders, and today, I want to dive deep into one that truly impressed me: the 24.5 inch portable monitor, specifically the hy300 pro+ model. Spoiler alert: it's not just a "big screen in a small package"—it's a game-changer for how we work, play, and connect.
First things first: when you unbox the hy300 pro+, the first thought that hits you is, "This can't be 24.5 inches." It's shockingly thin—just 7.2mm at its slimmest point—and weighs in at 1.2kg, which is lighter than most 15-inch laptops. I've carried it in my standard backpack for weeks now, and honestly? I barely notice it's there. The frame is made of anodized aluminum, which gives it a premium, matte finish that resists fingerprints (a huge win if you're as clumsy with coffee as I am).
What really sets this monitor apart, though, is its stand. Instead of the flimsy, foldable legs you'll find on cheaper models, the hy300 pro+ uses a design from the desktop tablet l-type series—a sturdy, adjustable L-shaped bracket that clicks into the back of the monitor. It lets you tilt the screen from 15 to 75 degrees, so you can find that perfect angle whether you're sitting at a desk or propped up in bed. I've even used it on my lap while watching movies, and it stayed steady without any wobbling. The stand is detachable, too, which is great if you want to mount the monitor on a tripod or VESA arm (though you'll need to buy the adapter separately).
Around the edges, you'll find all the ports you need, and they're thoughtfully placed. On the right side, there's a USB-C port (with Power Delivery, so it can charge your laptop while connected), an HDMI 2.1 port, a mini DisplayPort, and a micro USB for firmware updates. On the left, there's a 3.5mm headphone jack and a USB-A port—handy for plugging in a mouse or flash drive without fumbling for a hub. The power button doubles as a menu control, and there are physical buttons for brightness and volume, which I prefer over touch controls that can be finicky on the go.
Quick note: If you're used to smaller portable monitors (think 15.6 or 17.3 inches), the 24.5 inch size might feel intimidating at first. But after a day of using it, I found myself wondering how I ever survived with less. It's big enough to ｒｅｐｌａｃｅ a standard desktop monitor in a pinch, but still small enough to toss in a bag when you're done.
Let's talk about the star of the show: the display. The hy300 pro+ uses an IPS panel with a 2560x1440 resolution (QHD), which is a step up from the 1080p screens you'll find on most budget portable monitors. But numbers alone don't tell the story—you have to see it in person. Text is crisp enough that I could edit a 10-page document without squinting, and images pop with color that's both accurate and vibrant. I tested it with photos from my 10.1 inch wireless wifi digital photo frame (a gift from my sister, which I keep on my desk at home), and the colors matched almost perfectly—no washed-out blues or oversaturated reds here.
Brightness is another standout feature. At 400 nits, it's easily visible even in direct sunlight (I tested this by working outside on a sunny afternoon, and I didn't have to crank the brightness all the way up). That's a big deal if you're someone who works in variable lighting conditions—no more squinting through glare at the park or by a hotel window. The monitor also supports HDR10, which adds depth to dark scenes in movies or games. I streamed Dune: Part Two on a flight, and the contrast between the shadowy desert nights and bright sandworm attacks was stunning for a portable device.
What really impressed me, though, was the incell display technology. If you've heard the term "incell portable smart tv," you know it refers to screens where the touch sensors are built directly into the LCD panel, reducing thickness and improving touch responsiveness. While the hy300 pro+ isn't a touchscreen (more on that later), the incell tech here makes the display incredibly thin and lightweight without sacrificing durability. I accidentally knocked it off my desk onto a carpeted floor (don't ask), and there wasn't a scratch or dead pixel in sight. Plus, the anti-glare coating means fingerprints are barely noticeable—even after a long day of adjusting the screen.
A portable monitor is only as good as its ability to connect to your devices, and the hy300 pro+ nails this. I tested it with a MacBook Pro, a Windows laptop, an iPad Pro, and even my Android phone, and every connection was plug-and-play. The USB-C port is the real hero here—it works with Thunderbolt 4, USB4, and standard USB-C, so you don't need to worry about compatibility. With my MacBook, I just plugged in a single USB-C cable, and boom—my laptop charged, the monitor turned on, and my desktop extended instantly. No drivers, no software, no fuss.
For gamers, the HDMI 2.1 port is a game-changer (pun intended). It supports 144Hz refresh rates at QHD resolution, which means smooth gameplay with no lag. I hooked it up to my PS5, and titles like Spider-Man 2 looked incredible—fast-paced swinging sequences were buttery smooth, and the 24.5 inch screen made the action feel immersive without being overwhelming. The response time is 5ms (GtG), which is more than enough for casual gaming, though competitive gamers might prefer a 1ms panel. Still, for a portable monitor, this is top-tier performance.
One thing to note: the hy300 pro+ doesn't have a built-in battery. At first, I was disappointed—after all, some smaller portable monitors can run on battery for 4-6 hours. But the more I used it, the more I realized it's a trade-off worth making. Batteries add weight and bulk, and with Power Delivery via USB-C, I can plug it into a portable power bank (I use a 20,000mAh one) and get 3-4 hours of use away from an outlet. Plus, without a battery, the monitor stays cool—even during long gaming sessions, the back never got warm enough to be uncomfortable on my lap.
The 24.5 inch portable monitor isn't a one-size-fits-all gadget, but it's surprisingly versatile. Let's break down who will love it and who might want to look elsewhere.
Remote workers and students: If you split your time between home, coffee shops, and co-working spaces, this monitor is a dream. The size is perfect for multitasking—you can have your email and Slack on one side, and your document or spreadsheet on the other. I even used it as a primary monitor for a week while my desktop was being repaired, and I didn't miss a beat. The only downside? If you're constantly backpacking or hiking, the 24.5 inch size might be too bulky. Stick to a 15.6 inch model if portability is your top priority.
Content creators: Photographers, video editors, and designers will appreciate the color accuracy (100% sRGB and 95% DCI-P3 coverage) and QHD resolution. I edited a batch of travel photos on it, and the colors translated perfectly when I uploaded them to my 10.1 inch wireless wifi digital photo frame at home. The large screen also makes it easier to spot details—like a stray dust spot or uneven lighting—that might get lost on a smaller display.
Gamers and movie lovers: With 144Hz refresh rate, HDR10, and HDMI 2.1, this monitor is great for gaming on the go. It's also perfect for streaming movies—imagine setting it up in your hotel room and having a pseudo-home theater experience. Just remember: it doesn't have built-in speakers, so you'll need headphones or a portable speaker.
Frequent travelers: If you fly often, check the dimensions before packing. At 24.5 inches, it's too big for most under-seat bags, but it fits easily in a carry-on. I traveled with it on a 3-hour flight, and it slid right into my suitcase without taking up too much space. Just be sure to wrap it in a soft case to avoid scratches.
To give you a better sense of where the 24.5 inch portable monitor stands, I compared it to two popular alternatives: the 17.3 inch hy320 mini (a smaller, more budget-friendly option) and the 27 inch "ultra-portable" model from a rival brand. Here's how they measure up:
| Feature | 24.5 inch hy300 pro+ | 17.3 inch hy320 mini | 27 inch Rival Brand |
|---|---|---|---|
| Size | 24.5 inches (QHD) | 17.3 inches (1080p) | 27 inches (4K) |
| Weight | 1.2kg | 0.9kg | 2.1kg |
| Refresh Rate | 144Hz | 60Hz | 120Hz |
| Brightness | 400 nits | 300 nits | 350 nits |
| Ports | USB-C (PD), HDMI 2.1, mini DP, USB-A | USB-C (no PD), HDMI 2.0 | USB-C (PD), HDMI 2.1 |
| Price | $399 | $249 | $549 |
The hy320 mini is great if you prioritize portability over screen real estate—it's lighter and cheaper, but you'll sacrifice resolution, brightness, and ports. The 27 inch rival has a stunning 4K display, but it's almost twice as heavy and significantly more expensive. For most people, the hy300 pro+ hits the sweet spot: big enough to be useful, small enough to carry, and packed with features that justify the price tag.
After weeks of testing, I can confidently say: yes, the hy300 pro+ is worth every penny. It's not just a portable monitor—it's a portable workspace, entertainment center, and gaming hub rolled into one. The 24.5 inch size is a revelation; it's big enough to feel like a "real" monitor but small enough to take with you wherever you go. The display quality is top-notch, the connectivity options are versatile, and the build quality makes it feel like it will last for years.
If you're someone who works remotely, travels frequently, or just wants a better secondary screen, this monitor will transform how you use your devices. It's not the cheapest option out there, but if you value quality, performance, and versatility, the investment is justified. I've already recommended it to my colleagues, and I've even caught myself using it at home more than my desktop monitor—something I never thought would happen with a "portable" device.
At the end of the day, the 24.5 inch portable monitor (and specifically the hy300 pro+ model) proves that portable tech doesn't have to compromise on quality. It's a reminder that sometimes, the best gadgets are the ones that adapt to your life—not the other way around. So whether you're editing photos in a café, gaming on a flight, or just need more space to get work done, this monitor has your back. Trust me—once you go 24.5 inches, you'll never want to go back.
