Historically, you’ve had two options to expand the port capabilities of your laptop: an inexpensive USB-C dongle or a more powerful, pricey Thunderbolt docking station. A third option is quietly emerging, trying to split the difference. A DisplayLink docking station (sometimes called a USB-C dock) uses data compression to offer the capabilities of a Thunderbolt dock over a standard USB-C or Thunderbolt cable.
Why buy one? DisplayLink docking stations work great for normal day-to-day productivity, and historically the docks are cheaper and more stable than older Thunderbolt 3 desktop docks. They’re an upgrade over our picks for the best USB-C hubs dongles, and less expensive than the best Thunderbolt docking stations for your laptop. They can even support more displays than a native Thunderbolt dock. They’re just not suited for gaming.
If you need a fuller explanation of how DisplayLink works and what it offers, you’ll find that directly under our two recommended DisplayLink docks, below. You’ll also find a FAQ with answers to questions you might have. I base my recommendations on hands-on testing of the DisplayLink docking stations.
Why you should trust me: I’ve worked as a technology journalist for about 30 years, and at PCWorld for the last decade. I’ve tested dozens of USB-C hubs, Thunderbolt docks, and DisplayLink docking stations. I use a docking station in my daily work, connected to multiple 4K displays, and I typically review a handful of new products each month.
Updated Nov. 24, 2025 with some additional details from Synaptics.
Though I’ve tested a number of DisplayLink docking stations for laptops, I have two recommended docks. They’re the same picks that appear on PCWorld’s list of the best Thunderbolt desktop docks for your laptop.
USB-C hubs, Thunderbolt desktop docks, and now DisplayLink docking stations have emerged because of two factors: the growing ubiquity of do-anything USB-C ports, and the realization by laptop makers that they can use these ports to eliminate all the dedicated HDMI, microUSB, SD card slots, and USB-A ports that can clutter up their notebook PCs.
DisplayLink docks provide some of the native functions of a Thunderbolt dock, namely the ability to drive multiple high-resolution displays. Because of the inherent bandwidth limitations, DisplayLink docking stations offer a good choice for office workers, who can use those extra displays for static applications like email, chat, spreadsheets, or office work.
A USB-C port typically provides 10Gbps of bandwidth. Thunderbolt 3/4, which runs over the same physical USB-C port, supplies 40Gbps. In the real world, that typically means that a USB-C dongle can connect to a single 4K display (at 30Hz) while Thunderbolt can connect to two 4K displays, at 60Hz. DisplayLink can you give the advantages of a 40Gbps Thunderbolt connection via just a 10Gbps USB-C interface.
How? Data compression. A DisplayLink dock can either use a “traditional” 10Gbps USB-C connection, or take advantage of the extra bandwidth provided by an existing Thunderbolt 3 or 4 port. Either way, it uses data compression to squeeze more data throughput over the port. We use data compression every day, in photos and streamed video from YouTube and Netflix, and never notice. It’s the same here; your Windows desktop and applications will look the same.
DisplayLink is a technology owned by Synaptics, meaning it’s a proprietary standard. Each DisplayLink dock has a special DisplayLink chip built inside of it. (DisplayLink docks rarely, if ever, publish which Synaptics chip they use, so a DisplayLink dock’s capabilities may vary by product.)
DisplayLink’s data compression means there are two negatives to the technology, which we’ll get out of the way.
While USB-C and Thunderbolt work out of the box, DisplayLink requires a software driver. Without it, it will function as a generic USB-C dock. I’ve never seen any DisplayLink docks use their own unique drivers (though they may). In any case, you can use Synaptics’ official DisplayLink drivers. Most dock makers publish this information right up front, but not all do. (Be sure to reboot after installing it.)
DisplayLink works perfectly well for email, Word, Excel, and anything static, like a web page. But it does have limitations: 10Gbps is a nice chunk of bandwidth. But pushing a ton of data across it will cause images to stutter and hitch. In practice, this means that PC gaming on a DisplayLink dock is iffy: A slow-paced game like Baldur’s Gate 3 should be fine, but a frantic shooter like Battlefield or Helldivers 2 probably won’t give you a good experience at all. Playing 4K video from Netflix or YouTube? It shouldn’t be a problem. Playing 4K video while copying files from a hard drive and downloading a file? Everything will work, albeit slowly.
The big advantage for me is that DisplayLink tends to be really stable. Older Thunderbolt 3 hardware can be a little glitchy when connecting to multiple displays. In my experience, DisplayLink docks aren’t. That matters to some people.
DisplayLink (often with a DisplayLink 4K logo on it) can also connect to multiple displays, even more than Thunderbolt. I don’t have room to neatly show off a photo of three or even four displays, but trust me — I’ve tried it on multiple occasions, and it works. The hitch is that your laptop has to be capable of rendering on four displays, and you’ll typically need to close your laptop to do so. That may mean adjusting the Windows Control Panel to tell your laptop to leave it up and running.
Can I get a bit nerdy for a second? When you use a DisplayLink dock to connect to more than two displays, there’s even more magic going on behind the scenes. Take a DisplayLink dock like the Plugable UD-6950PDZ, which supports three 4K displays at 60Hz. It uses Synaptics’ most advanced chip, the DL-6950. But the DL-6950 only supports a pair of displays. To enable a third external display, the dock is using DisplayLink for two displays, and your laptop’s own “normal” DisplayPort connection (called DisplayPort Alt Mode) to drive the third.
That brings up the final point that I always have to make: Recent hardware is best. A standard DisplayLink docks works best on, say, a 10th- or 11th-gen Core processor or a complementary AMD Ryzen laptop. With anything more advanced — 12th-, 13th-, and 14th-gen — you should have a pretty ideal experience.
To be fair, Synaptics feels that you should be able to use older hardware with DisplayPort, and it should just work. “Regardless of your PC’s specs or age, DisplayLink docks will efficiently allocate bandwidth to handle your network connection and other peripherals, ensuring optimal performance,” a Synaptics representative says.
That’s a fair objection. But I’m still more comfortable recommending more modern hardware, perhaps because I’m a little gun-shy after using other USB-C hardware.
I use the same methodology to test DisplayLink docks as I do to test Thunderbolt docking stations. Here’s a synopsis.
First, I take the dock from its packaging and evaluate its construction. I measure the cord length and check the dock’s physical dimensions with a ruler.
I’ll then read the manual: Does the dock need any drivers? (Yes it will.) Are there links? What does the manual say about the dock’s capabilities, in terms of power and speed?
Next, I take a USB key or two and connect them to the available USB ports to determine if they have enough space to allow several to be connected at the same time. I then examine the display ports, find the appropriate cables, and then connect the dock to the laptop. I use a series of laptops with various generations of AMD and Intel hardware, and check to see if the experience is the same on each one. If it isn’t, I make notes.
I then measure the power output of the ports, using a USB multimeter, a smartphone, and a laptop to measure how much power the dock delivers to a laptop.
Finally, I check to see how well the dock performs under load. I use a specific test laptop for this purpose for repeatable results. I stream a 4K60 YouTube video using the Ethernet port on the dock (if it has one) and note any dropped frames. I usually check with a pre-recorded 4K60 video running from an SSD.
I then run PCMark 10’s SSD storage benchmark off of a test SSD, connected to the dock. I measure the score, then measure the score again while streaming a video. I then copy a large, multigigabyte folder of various files from my laptop across the bus and measure the time it takes to do so. I repeat the test while streaming video.
Finally, I check the operation and performance of any SD card slots the dock has and listen to audio through the audio jack, to make sure it works.
