In today's fast-paced world, portable monitors have become more than just a luxury—they're a necessity. Whether you're a remote worker juggling spreadsheets, a student taking online classes, or a gamer looking to extend your screen real estate, a portable monitor like the 24.5 inch portable monitor can transform how you work, learn, or play. But here's the thing: even the best portable monitor is only as good as the accessories you pair with it. From tangled cables to limited ports, small frustrations can quickly turn your seamless setup into a hassle. That's why we've rounded up 12 must-have connection accessories to make your portable monitor experience smoother, more efficient, and infinitely more enjoyable. Let's dive in!
Let's start with the basics: ports. Modern laptops, especially ultrabooks and MacBooks, are notoriously light on ports—often boasting just one or two USB-C slots. If your portable monitor relies on USB-C for power and display (which most do these days), you're left with zero ports for your mouse, keyboard, or external hard drive. Enter the USB-C hub. Think of it as a power strip for your tech: plug it into your laptop's single USB-C port, and suddenly you've got HDMI, USB-A, SD card readers, and even an Ethernet port at your fingertips.
When shopping for a hub, look for one with at least 4K HDMI output (to match your portable monitor's resolution) and 100W Power Delivery (PD) to keep your laptop charged while you use the monitor. Brands like Anker and Belkin make reliable options, but even budget-friendly picks from Aukey or UGreen work great. Pro tip: If you often connect multiple devices, opt for a hub with a built-in USB-C port—this way, you can charge your phone or tablet without unplugging the monitor.
HDMI cables are the unsung heroes of connectivity, but not all are created equal. The flimsy, plastic-coated cables that come in the box? They fray, tangle, and sometimes even fail to deliver 4K resolution. For a portable monitor setup, you need something sturdier. Braided HDMI cables are game-changers: the nylon or polyester braid protects the internal wiring from kinks and tears, while gold-plated connectors ensure a stable, interference-free signal.
Length matters, too. If your desk is small, a 3-foot cable keeps things tidy. For larger setups (or if you like to sit back from the screen), go for 6 feet. And don't skimp on specs: aim for HDMI 2.1 if your monitor supports 4K at 60Hz (most modern portable monitors do), or HDMI 2.0 for 4K at 30Hz. This ensures smooth video playback and lag-free gaming—no more blurry text or choppy streams.
Cables are reliable, but they're also a tripping hazard—especially if you move your portable monitor around often (say, from your desk to the couch). A wireless HDMI transmitter solves this problem by sending video and audio from your device to the monitor over Wi-Fi. Simply plug the transmitter into your laptop or phone and the receiver into your monitor's HDMI port, and voilà: instant, cable-free connection.
Look for a transmitter with low latency (under 20ms) if you're gaming or watching movies—no one wants lag during a crucial boss fight or plot twist. Brands like Nyrius and IOGEAR offer models that support 4K, and some even work with multiple monitors. Just keep in mind: wireless transmitters require power, so you'll need to plug the receiver into an outlet or use a USB port on the monitor.
You've got your monitor connected, but is it at the right height? Hunching over a portable monitor placed flat on your desk can lead to neck strain, eye fatigue, and even chronic pain over time. A monitor stand isn't just about aesthetics—it's about comfort. Adjustable stands let you raise or lower the screen to eye level, tilt it for better viewing angles, and even swivel it from landscape to portrait mode (perfect for reading long documents or coding).
For portability, opt for a foldable stand like the HUANUO Laptop Stand, which collapses to the size of a book and weighs next to nothing. If you're set up at home, a desk-mounted arm (like the Ergotron LX) gives you ultimate flexibility—you can swing the monitor out of the way when not in use, freeing up desk space. Bonus: Many stands have built-in cable management to keep those messy wires under control.
Not all devices play nice with HDMI. If you're using an older laptop, desktop, or gaming console with a DisplayPort output (common on Dell, HP, and Lenovo machines), you'll need an adapter to connect to your portable monitor's HDMI port. DisplayPort adapters are small, affordable, and plug-and-play—no drivers required. Just make sure to get one that supports the resolution of your monitor. For example, if your 24.5 inch portable monitor runs at 4K, look for an adapter labeled "DisplayPort 1.4 to HDMI 2.1" to ensure you're not stuck with 1080p.
Pro tip: Avoid cheap, unbranded adapters. They're prone to signal dropouts and can even damage your devices. Stick with trusted brands like StarTech or Cable Matters—they're worth the extra $5 for peace of mind.
One of the best things about portable monitors is their portability—but that goes out the window if you're tethered to a wall outlet. A high-capacity power bank lets you use your monitor on the go, whether you're working from a coffee shop, traveling on a train, or even camping (yes, people do that!). Look for a power bank with at least 20,000mAh and a USB-C port that supports PD. Most portable monitors draw around 30-60W of power, so a 20,000mAh bank should give you 2-3 hours of use. For all-day use, splurge on a 30,000mAh model—just be prepared for a bulkier design.
Brands like Anker, RAVPower, and Zendure make excellent PD power banks. Just check the fine print: some banks only support PD up to 60W, which is enough for most 15.6-24 inch monitors, but if you have a larger model, you may need 100W PD.
There's nothing worse than trying to work on your portable monitor in a sunlit room, only to be blinded by reflections. An anti-glare screen protector is a cheap fix that makes a world of difference. These thin, matte films reduce glare and fingerprints, making your screen visible even near windows or overhead lights. They also add a layer of scratch protection—handy if you toss your monitor into a bag without a case.
When applying a screen protector, take your time! Bubbles are the enemy, but most kits come with a squeegee and dust remover to help. If you're nervous about DIY, many electronics stores offer professional installation for a small fee. For touchscreen portable monitors, opt for a protector labeled "touch-sensitive"—it won't interfere with responsiveness.
Portable monitors are built to move, but that doesn't mean they're indestructible. A good carrying case is non-negotiable if you take your monitor to work, school, or on trips. Look for a case with a hardshell exterior to protect against drops, a soft interior lining to prevent scratches, and a padded shoulder strap for easy carrying. Many cases also have compartments for cables, adapters, and your hub—so you're not fumbling through a messy bag to find what you need.
For the 24.5 inch portable monitor, check the dimensions before buying—some cases are designed for 15 or 17 inch screens and won't fit larger models. Brands like tomtoc and Case Logic make durable, stylish options that balance protection and portability.
Why stop at one portable monitor? If you're a multitasking pro who needs to keep emails, Slack, and a spreadsheet open all at once, a multi-monitor splitter lets you connect two or more monitors to a single device. Splitters come in HDMI and USB-C varieties; HDMI splitters are best for gaming consoles or older laptops, while USB-C splitters (like the Plugable USB-C Triple Display Dock) work with newer devices and often include extra ports.
Note: Not all laptops support multiple external monitors. Check your device's specs—most modern laptops can handle 2-3 displays, but some budget models may only support one. If you're unsure, a quick Google search for "[your laptop model] multiple monitors" will give you the answer.
Portable monitors are great for video calls and movies, but many skimp on built-in speakers (or have speakers that sound like tin cans). If you want to connect external headphones, earbuds, or a Bluetooth speaker, an audio adapter is a must. For USB-C devices, a USB-C to 3.5mm adapter is tiny and affordable—just plug it in and you're ready to go. If your monitor has an HDMI ARC port, you can even connect a soundbar directly for theater-like sound.
Gamers, take note: A low-latency audio adapter is key for competitive play. Look for one with a built-in DAC (digital-to-analog converter) to improve sound quality—brands like FiiO and Creative make adapters that deliver crisp, clear audio without lag.
USB-A ports (the classic rectangular ones) are still everywhere: on printers, external hard drives, and even some older monitors. If your laptop only has USB-C ports, a USB-A to USB-C cable lets you connect these legacy devices without a hub. These cables are also useful for charging your monitor from a USB-A power source (like a wall charger or power bank) if you don't have a USB-C charger handy. Just be aware: USB-A to USB-C cables can't deliver video or high-speed data—they're strictly for charging and basic file transfers. For display or fast data, stick to a USB-C hub or direct USB-C connection.
Last but not least: a clean screen. Fingerprints, dust, and smudges don't just look gross—they can distort colors and strain your eyes. A good cleaning kit includes a microfiber cloth (never use paper towels—they scratch!), a gentle screen cleaner (alcohol-free, to avoid damaging coatings), and a dust blower (to remove crumbs and lint before wiping). Brands like WHOOSH! and AmazonBasics make affordable kits that last for months. Get in the habit of cleaning your screen once a week, and your portable monitor will look brand-new for years.
