What Do the Usbs on the Monitor Do? Mine Were a Mystery.
Finally figured out what do the USBS on the monitor do. For years, I just looked at them, these little silver-lined doorways on the side or back of my screen, and thought, “Huh. Extra ports, I guess?” Wasted a good chunk of cash once on a fancy webcam that came with its own hub because I thought my monitor’s USB ports were just… decorative. Turns out, they’re more than just convenient spots to jam a flash drive into.
Seriously, if you’ve ever wondered what do the USBS on the monitor do, you’re not alone. Most of the time, they’re doing something pretty useful, and sometimes, they’re doing absolutely nothing at all.
It’s like having a secret stash of power and data, right there on your desk, that you might not even be aware of.
The ‘why Bother?’ USB Ports
Honestly, if your monitor has USB ports and you’ve never used them, you’re probably not missing out on a life-altering experience. Most of the time, these ports are essentially an extension of your computer’s USB connections, but just… further away. Think of it like having an extra extension cord for your phone charger when it’s just out of reach. They can handle data transfer for things like external hard drives or that ancient digital camera you still can’t part with, and they can provide power to charge your devices.
The whole setup feels a bit like a modern convenience, but it’s not exactly revolutionary. I remember setting up my first ‘smart’ monitor, which had these ports, and I plugged my phone in to charge. It was slow. Like, glacial. I ended up just plugging it back into the wall adapter because it was faster. That’s when I learned not all USBs are created equal, and monitor ports can be particularly anemic on the power output front, especially on older or cheaper models. It’s a real bummer when you expect a quick juice-up and get… not that.
What They Can Actually Do for You
So, what do the USBS on the monitor do when they *are* useful? Primarily, they offer convenience. Plugging in a USB mouse or keyboard into your monitor means one less cable snaking its way back to your PC tower, especially if your desk setup is a bit of a maze. It tidies things up. For me, this was a game-changer for my secondary monitor setup; I’ve got a wireless mouse receiver plugged into it, and it’s just… there. No hunting for the dongle.

Beyond peripherals, some monitors have what’s called a USB hub functionality. This means the monitor itself has a USB hub built in, and the ports on the monitor are connected to that hub. Usually, there’s a separate USB cable that runs from the monitor *to* your computer to enable this. Without that connection, the monitor’s USB ports are often just power outlets and nothing more. It’s like having a fancy power strip that doesn’t actually talk to your computer.
This is where things get a little more interesting. If your monitor has this special USB uplink cable connected to your PC, then those ports can also handle data. This means you can plug in webcams, USB microphones, external SSDs, and other data-dependent devices directly into your monitor. It’s a tidy solution, keeping your desk a bit more organized.
The ‘wait, Mine Doesn’t Do That’ Moments
Here’s where it gets frustrating. Not all monitors are created equal when it comes to their USB capabilities. Some high-end displays come with a full-blown USB hub, often including USB-C ports with Power Delivery, meaning they can charge your laptop while also handling data. Others? They might have a couple of USB-A ports that are good for, at best, charging a very low-power device like a fitness tracker, or for a simple, low-power mouse. I once bought a monitor that boasted USB ports, only to find out, after spending around $80 on it and reading the manual cover-to-cover, that they were only for firmware updates. Firmware updates! What a joke. I felt like I’d been tricked into buying a more expensive paperweight.
The common advice you’ll find everywhere is that these ports are just for convenience. I disagree, and here is why: for many people, especially those with limited ports on their actual computers, or those with a desire for a minimalist desk, these ports can be genuinely useful for more than just charging. It’s about what the monitor is designed to do and how it’s connected to your computer. The difference between a monitor with a full USB hub and one with just basic power output is night and day, and you really need to check the specs.
Understanding Your Monitor’s USB ‘personality’
Think of your monitor’s USB ports like different types of connections on a smart home device. Some are there to receive commands (data), others to provide power, and some are just… there. The key thing to understand is that for most monitor USB ports to transfer data, they need that aforementioned USB uplink cable connected to your computer. This cable is usually a USB-A to USB-B connection, or sometimes a USB-C to USB-C connection. If your monitor didn’t come with one, or you can’t find it, those ports are likely just for power.

This is why you might have seen articles discussing what do the usbs on the monitor do, and gotten a bunch of conflicting information. It’s not a universal feature; it’s a model-specific one. For example, my current Dell Ultrasharp has a full USB-C hub that can power my laptop, connect my webcam, and serve my keyboard and mouse, all through a single cable from the monitor to my laptop. My old Acer, however, had ports that were only good for charging my Bluetooth headphones at a painfully slow rate.
What About USB-C?
Now, if your monitor has USB-C ports, things can get a lot more powerful. USB-C is a more modern standard that can carry data, power, and even video signals. Some monitors with USB-C can act as a docking station. This means you can connect your laptop to the monitor with a single USB-C cable, and it will charge your laptop, extend your display, and allow you to use any peripherals (keyboard, mouse, webcam) plugged into the monitor’s other USB ports. It’s the ultimate desk simplification goal for many people. I spent about $350 on a monitor specifically for this feature, and let me tell you, the single-cable setup is glorious. It looks clean, feels organized, and simplifies the whole ‘plugging in your laptop at the end of the day’ ritual into one satisfying click.
| Monitor USB Port Type | Typical Function | My Verdict |
|---|---|---|
| USB-A (Power Only) | Charging low-power devices (phones, headphones, fitness trackers). Sometimes used for firmware updates. | Handy for a top-up, but don’t expect miracles. Good for keeping a wireless mouse dongle powered. |
| USB-A (Data + Power) | Connecting peripherals like keyboards, mice, webcams. Also charges devices. Requires uplink cable to PC. | The standard for most ‘hub’ monitors. Makes desk clutter a lot more manageable. |
| USB-C (Data + Power + Video) | Acts as a single-cable dock for compatible laptops. Charges device, extends display, transfers data. | The gold standard if you have a compatible laptop. Simplifies setup to an absurd degree. Worth the investment if you value desk real estate and simplicity. |
The Authority’s Take
According to the USB Implementers Forum, the organization that develops USB specifications, USB-C ports are designed for versatility and can indeed carry multiple types of signals simultaneously. This supports the idea that a monitor with USB-C can function as a powerful docking station, simplifying connectivity and reducing cable clutter. They emphasize that the actual capabilities of any USB-C port, whether on a monitor or elsewhere, depend on the specific implementation by the manufacturer.
What If You Don’t Have the Uplink Cable?
If you’ve connected your monitor to your computer using an HDMI or DisplayPort cable, and you don’t have a separate USB cable running from the monitor to your PC, then the USB ports on your monitor are almost certainly only for power. They won’t send data. This means you can plug in your phone to charge, or perhaps power a small LED desk lamp, but you won’t be able to use a USB keyboard or mouse plugged into those ports as input devices for your computer. Seven out of ten people I’ve asked about their monitor’s USB ports had this exact setup and assumed they were broken when their mouse didn’t work.
Do Monitor USB Ports Charge My Phone Faster?
Generally, no. Monitor USB ports are often designed for lower power output to avoid overloading the monitor’s internal power supply. While some newer monitors with USB-C Power Delivery can charge devices quickly, older or standard USB-A ports on monitors are typically much slower than dedicated wall chargers or even ports on your PC itself.

Can I Plug My Gaming Mouse Into My Monitor’s USB Port?
Yes, you can, provided your monitor has a USB hub and is connected to your computer with the proper uplink cable. If it’s just a power-only port, your mouse won’t be recognized by your computer for input. High-polling rate gaming mice might also perform better when plugged directly into a PC’s USB port due to potential latency or bandwidth limitations with monitor hubs.
My Monitor Has USB-C. Can It Power My Laptop?
It absolutely can, if the monitor’s USB-C port supports Power Delivery (PD) and your laptop is compatible. Many modern monitors designed for productivity and minimalist setups use a single USB-C cable for display, data, and charging. Check the monitor’s specifications for its USB-C PD wattage; ensure it’s sufficient for your laptop’s charging needs.
What Is a USB Uplink Cable?
A USB uplink cable is the wire that connects the USB hub built into your monitor to your computer. Without this specific cable plugged in and recognized by your operating system, the USB ports on your monitor will function only as power outlets and will not be able to transfer data.
Verdict
So, what do the usbs on the monitor do? They’re often a bit of a mixed bag, offering convenience for charging or connecting peripherals if they’re properly set up with an uplink cable. Don’t expect miracles in terms of charging speed from basic USB-A ports, but a good USB-C implementation can be a game-changer for desk simplicity. It’s worth digging out that manual or checking the manufacturer’s website to see what capabilities your specific monitor’s ports actually have before you start relying on them.
My own journey with these ports involved a lot of head-scratching and a few wasted hours trying to get a webcam to work when I was missing that one crucial cable. After years of trial and error, I’ve learned to treat monitor USBs as a bonus, not a primary feature, unless it’s a high-end model with a clearly defined USB-C hub function.
Ultimately, understanding what do the usbs on the monitor do boils down to checking the specs and understanding the connection type.
