- Triple display support without needing Thunderbolt
- 140W charging capacity
- 14 ports means fewer other cables on the desk
- Driver install required, per Anker's own listing
- DisplayLink adds CPU load and won't play DRM video like Netflix
The 30-second verdict
The Anker Prime DL7400 is a genuine three-monitor dock for folks who don't have Thunderbolt available. It'll do what you ask. But here's the catch: you're installing software, using some processor power, and streaming services like Netflix won't show up on those external screens. Want three monitors and you know what DisplayLink actually is? Get it. Want three screens but think you're getting Thunderbolt performance for the price? You'll be sending it back by week two.
Who this is for
Say your USB-C laptop has no Thunderbolt port. Plenty of Windows machines fall into that category, along with older MacBook Airs and some iPad Pros. Say you need exactly three external monitors, or at least want the option open. If you can tolerate a driver install and you’re not streaming video full-time on those screens, this works. One cable from the laptop, no separate USB hub required.
The 14-in-1 port count is real: three HDMI + three DisplayPort outputs, plus USB-A, USB-C data, SD and microSD, 3.5mm audio, and RJ45 Ethernet. That is desk-clutter reduction if you have been plugging in cables one by one.
What DisplayLink actually means
DisplayLink is a technology that compresses video, sends it over USB, and decompresses it on your monitor or the dock’s own processor. It is not a cable passthrough like Thunderbolt or USB4. Anker’s own listing states “Driver Install Required”—that is the first honest signal.
Then there’s CPU load. Tom’s Hardware measured DisplayLink on a capable mobile Core i5 at roughly 15% of the CPU just moving a mouse, climbing to 20 to 30% during window-dragging bursts. Coding, video editing, or CAD work will make that tax noticeable. Browsing and Slack won’t.
Then there’s DRM video. Netflix, Hulu, Prime Video, and Disney+ won’t play over DisplayLink because they treat it as an insecure pathway. Plugable’s own knowledge base confirms it. If those three monitors are meant for watching video while you work, that’s a real problem. If they’re for code, spreadsheets, and reference material, it isn’t.
The fourth is refresh rate. DisplayLink tops out at 60Hz. No 120Hz, no gaming, no super-smooth scrolling. It is sufficient for almost all work; it is not invisible in motion.
What it gets right
The 140W charging capacity is real and certified, enough for nearly every laptop under 17 inches, including the 16-inch MacBook Pro with its 140W brick. Build quality holds up too: the industrial design is clean, and nothing wobbles or feels cheap. Port count is genuine as well, which spares you from daisy-chaining extra hubs.
Running three monitors off a laptop often means separate USB hubs, tangled cables, and extra power bricks. Consolidating all that into this single dock is a genuine reduction in desk chaos. It’s also the only DisplayLink option in the $300 price band that doesn’t require a desktop-class Windows or macOS system to make it work.
Setup is straightforward: plug the dock into USB-C power and your laptop, download the driver from Anker’s support page (not auto-installed), restart. That restart is mild friction compared to the driver-not-found nightmare of cheap knockoffs.
The real question: DisplayLink or wait for Thunderbolt?
If your laptop has Thunderbolt 4 or 5, you should be looking at a different dock entirely—the USB-C Hub with HDMI budget options are simpler and faster. The Powered USB Hub Buying Guide covers docks that do not require a driver at all.
If you are on USB-C without Thunderbolt and you genuinely need three monitors, the DL7400 is the correct answer. There is no other dock at this price that does it without either requiring Thunderbolt or forcing you to buy a second USB hub.
The alternative is accepting two monitors—nearly every USB-C hub for laptops handles two HDMI outputs at 4K60. Two monitors solve most desk-layout problems. Three monitors are a comfort, not a requirement, unless your work actually demands it.
The CPU load trap
That 4.0 rating from 761 reviews exists because the dock itself isn't defective. It's there because plenty of people installed the driver, didn't realize DisplayLink takes 15–30% of your CPU to handle video, and then blamed the dock when their machine felt slower. Know upfront that's the trade-off you're making, and you'll be fine. Assume you're buying a speedier Thunderbolt alternative and you'll regret it.
Compare that to the USB-C Hub With Power Delivery guide, where docks without DisplayLink sit at 4.3 to 4.4 for the same price range. That gap in ratings comes almost entirely from DisplayLink’s CPU cost, not build quality.
Buy it if
Picture this setup: USB-C without Thunderbolt, a genuine need for three external monitors, and an understanding that DisplayLink reserves CPU time and blocks video streaming apps on those screens. You want one cable out of the laptop and fewer cables cluttering the desk overall. Installing a driver doesn’t bother you.
Skip it if you have Thunderbolt, if you only need two monitors, if streaming video is a primary use case, or if you are sensitive to system latency. The USB hub hub has alternatives for all of those.

Questions people ask about the Anker Prime DL7400 Docking Station
It's built for USB-C laptops without Thunderbolt—many Windows machines, older MacBook Airs, and some iPad Pros. Since it runs on DisplayLink rather than Thunderbolt passthrough, you don't need a Thunderbolt port at all, which is the whole point of this dock. Compatibility depends more on whether your laptop's USB-C port supports video output and power delivery than on Thunderbolt specifically. Check your laptop's spec sheet for USB-C alt mode support.
The two real failure points are CPU load and DRM video. DisplayLink compresses and decompresses video over USB, which measured roughly 15% CPU just moving a mouse and 20-30% during window-dragging on a capable Core i5. If you're coding, editing video, or running CAD, you'll feel that tax. Netflix, Hulu, Prime Video, and Disney+ also refuse to play over DisplayLink outputs entirely, so streaming on those external screens is a dead end.
It depends on how many monitors you need and whether you have Thunderbolt already. A basic USB hub won't drive three external displays without Thunderbolt or DisplayLink tech—that's the whole reason this dock costs more. If you only need one or two monitors and your laptop has Thunderbolt, a simpler passthrough hub avoids the driver install and CPU overhead entirely. Three monitors without Thunderbolt is where this dock's 14-in-1 setup earns its keep.
