Running a 4K monitor at 120Hz through a dock needs a lot of bandwidth, and the headline "4K" on many docks means 60Hz. Of the eight docks here, three list 4K at 120Hz or higher: the TobenONE DL7400, a budget dual-monitor dock rated to 144Hz, and a KVM dock. The others top out at 4K 60Hz or do not state a refresh rate, and are included as alternatives for other needs.
Your laptop matters as much as the dock. Native high-refresh output generally needs Thunderbolt or a USB-C port with enough DisplayPort bandwidth, and on Macs, DisplayLink docks are commonly limited to lower refresh rates. Check your laptop's documented display support before buying.
Our comparison is based on published specifications and price position, not hands-on testing. Prices range from about $99 to $330 at the time of writing.

Our Picks
Best for Multiple 4K 120Hz Monitors1 of 8
TobenONE 18-in-1 DisplayLink Docking Station (DL7400) on Amazon (opens in a new tab)
The TobenONE DL7400 is the dock for large high-refresh setups: TobenONE lists up to five monitors, including four at 4K 120Hz, through DisplayLink and five HDMI outputs, with a cooling fan.
Best for
- Windows users running several 4K high-refresh monitors.
Skip if
- You use a Mac and need native high refresh; DisplayLink may limit it.
Why we like it
It adds 2.5GbE and 45W charging. The 4K 120Hz support is listed for Windows and requires a driver.
It is the most expensive dock here at the time of writing, 45W charging is modest, and DisplayLink output is less suited to color-critical work and may behave differently on macOS.
Key dimensions & specs
- Monitors: up to 5 (DisplayLink)
- Quad 4K 120Hz (Windows, driver required)
- Outputs: 5 x HDMI
- Cooling fan
- 2.5GbE; charging: 45W
Pros
- Most high-refresh displays here
- 2.5GbE
- Active cooling
Cons
- Most expensive
- Driver required
- 45W charging

TobenONE 20-in-1 DisplayLink Docking Station, Quad 4K@60Hz on Amazon (opens in a new tab)
This TobenONE runs four 4K monitors at 60Hz, not 120Hz, so it suits productivity over high refresh.
Best for
- Four-monitor productivity setups.
Skip if
- You need 120Hz; this dock lists 60Hz.
Why we like it
It has a 150W power supply, six USB ports, Ethernet and SD readers, and works with Thunderbolt and USB-C laptops across Windows, ChromeOS and macOS.
Choose it if four screens matter more than smooth motion.
Key dimensions & specs
- Monitors: 4 x 4K 60Hz (DisplayLink)
- Power supply: 150W
- USB: 6; Ethernet; SD/microSD
- Thunderbolt 3/4/5 and USB-C

Best Budget High-Refresh Dock3 of 8
USB C Docking Station, Dual Monitor 4K@144Hz on Amazon (opens in a new tab)
This unbranded dock is the budget route to high refresh: it lists dual monitors at up to 4K 144Hz over two HDMI and two DisplayPort outputs, with a 150W DC input, Ethernet, 10Gbps USB-C and card readers.
Best for
- Two high-refresh monitors on a budget.
Skip if
- You want an established brand; consider the Plugable or KVM options.
Why we like it
Reaching 144Hz on two 4K screens depends heavily on your laptop's USB-C or Thunderbolt bandwidth, so check what your laptop supports.
The brand is not named in the listing.
Key dimensions & specs
- Displays: dual, up to 4K 144Hz (listed)
- Outputs: 2 x HDMI, 2 x DisplayPort
- Power input: 150W DC

KVM Dock for Two Computers4 of 8
AV Access 8K KVM Switch Dock, 2 Monitors 2 Computers on Amazon (opens in a new tab)
The AV Access dock solves a different problem: it switches two monitors and your peripherals between two computers, such as a work laptop and a desktop, without replugging.
Best for
- Desks shared by two computers.
Skip if
- You need confirmed 4K 120Hz switching; the 13-in-1 KVM dock lists it.
Why we like it
It lists an 8K resolution ceiling, Gigabit Ethernet and EDID emulation to keep displays detected when switching.
The listing does not state 4K 120Hz support, so check it if refresh rate matters.
Key dimensions & specs
- KVM: 2 computers, 2 monitors
- Resolution ceiling: 8K (listed)
- Gigabit Ethernet
- EDID emulation
Pros
- Shares monitors between two PCs
- EDID emulation
Cons

Best Thunderbolt Dock for Mac5 of 8
Plugable Thunderbolt 4 Dock for M4/M5 MacBook (TBT-UDM) on Amazon (opens in a new tab)

Best for
- Mac users who want native output and a certified dock.
Skip if
- You need guaranteed 4K 120Hz on two screens; check your Mac's limits first.

What to Look for in a Dock for 4K 120Hz Monitors
Key buying criteria so you get the right fit the first time.
Listed refresh rate
Only the TobenONE DL7400, the 144Hz dual dock and the 13-in-1 KVM dock list 4K at 120Hz or more. "4K" alone usually means 60Hz.
Your laptop's output
High refresh needs enough bandwidth from the laptop's Thunderbolt or USB-C port. Check its documented display support.
DisplayLink or native
DisplayLink adds screens beyond the laptop's limit but needs a driver, adds processor load and may cap refresh, particularly on macOS. Native Thunderbolt avoids that.
Two computers
A KVM dock (AV Access, 13-in-1 KVM) shares monitors and peripherals between two machines.

Frequently Asked Questions
Which docks here support 4K at 120Hz?
The TobenONE DL7400 (on Windows, with a driver), the budget dual dock listed to 4K 144Hz, and the 13-in-1 KVM dock.
Why does my monitor run at 60Hz through a dock?
The dock, the cable or the laptop's port may lack bandwidth for 4K 120Hz. Check each against the listed specifications.
Can a Mac run 4K 120Hz through a DisplayLink dock?
DisplayLink is commonly more limited on macOS. A native Thunderbolt dock is the safer route; check your Mac's chip for its display limits.
What is a KVM dock?
A dock that lets two computers share the same monitors, keyboard and mouse, switching between them without replugging.
Bottom Line
For genuine 4K high-refresh setups, the TobenONE DL7400 handles the most screens on Windows, the budget dual dock is the low-cost route to 144Hz on two monitors, and the 13-in-1 KVM dock is the choice for two computers.
The Plugable is the native option for Macs, and the TobenONE 20-in-1, WAVLINK, Anker Prime and AV Access are capable docks for other priorities, but do not list 4K 120Hz.
