Check your laptop’s external-display limit and host-port video support before choosing a dock for two monitors. A native USB-C or Thunderbolt dock is worth considering when the laptop supports the intended display setup; a compatible USB-A DisplayLink dock offers another route for an older laptop, but needs software and can affect protected-video playback on macOS. If the laptop already has two usable display connections, direct monitor cables plus a USB hub may meet the need with fewer compatibility questions, though you may have more cables at the desk.
If you want two monitors and desk peripherals on one connection, check the exact laptop’s supported external-display count and video-capable ports first. Then compare the dock’s display modes and charging provision with your intended setup.
A DisplayLink dock with an appropriate USB-A host connection is a route to investigate when the laptop lacks USB-C video output. Confirm that the dock supports your operating system and both monitors’ intended settings.
Apple Support says the number of simultaneous external displays depends on the Mac model and each display’s resolution and refresh rate. Check your model’s limit before choosing a native dock; if considering DisplayLink, account for its macOS software requirement and protected-video limitation.
Start with the laptop and the two monitors, then decide whether a native-video dock, a DisplayLink dock or direct display cables with a USB hub meet your needs.
| Priority | What to check | Your needs |
|---|---|---|
| Two independent displays | Find the exact laptop model’s external-display limit and video-capable ports. Compare its supported resolution and refresh rate with both monitors and the dock; if it has two independently usable display connections, consider connecting the monitors directly. | I want both monitors to show separate work, not merely find two video sockets on a dock. Apple Support notes that a hub or daisy chain does not raise a MacBook Air model’s maximum external-display count. |
| Desk connections and charging | List the USB, Ethernet and other connections your peripherals need. Compare the dock’s delivered or pass-through power with the laptop’s charging requirement, and check whether the necessary power supply and host cable are included. | One connection for my keyboard, mouse and displays would keep the desk simpler, but I also need to know whether the laptop will charge through it. |
| Software and everyday use | For DisplayLink, check support for your installed operating system and the exact dock’s driver instructions. On macOS, account for DisplayLink Support’s warning that some protected video may not play while DisplayLink screens are connected. | If my older laptop needs a USB-A dock, I can consider DisplayLink for desk work. If watching protected streaming video on a Mac is important, that limitation changes my choice. |
| Appropriate display mode | Compare each monitor’s intended resolution and refresh rate with the exact dock specification and the laptop’s capability. Consider Thunderbolt only if the laptop supports it and its capabilities address your display or peripheral requirements. | I want to choose for the monitors I will actually connect, rather than rely on a high display rating that my laptop cannot use. Targus UK specifies dual HD output for the DOCK116GLZ; that is not a dual 4K specification. |
Two video outputs on a dock do not establish that a particular laptop can drive both monitors at your chosen settings. Apple Support specifically says a hub or daisy chain does not increase a MacBook Air model’s external-display maximum.
Look up the exact laptop model’s display limit, then check the dock’s compatible modes against both monitors’ resolution and refresh rate.
DisplayLink depends on operating-system software. DisplayLink Support also warns that some protected video may not play on a Mac while DisplayLink screens are connected; individual docks have their own output limits.
Check the exact dock’s driver support and display modes, especially if protected streaming or gaming is part of the intended use.
Charging depends on the dock, its power source and the laptop. Dell UK lists 100W for Dell systems and 96W for non-Dell systems on the WD25, while Targus UK describes the DOCK116GLZ as offering up to 80W power-delivery pass-through.
Compare the laptop’s charging requirement with the applicable dock rating, and check what power supply comes in the package.
If the available power is insufficient or the laptop cannot charge through that port, you may need to keep using its original charger.
UK government guidance on waste electrical and electronic equipment describes measures intended to encourage recovery, reuse and recycling of electrical products.
When replacing a dock, check the available retailer take-back or local-authority electrical-waste route.
These models illustrate different connection routes; the brand name alone cannot establish compatibility with your laptop.
Dell UK lists the Pro Dock WD25 as a USB-C desk dock with video connections and laptop power delivery.
Targus UK’s DisplayLink-based DOCK116GLZ offers a USB-A legacy host adapter for a compatible older laptop.
Plugable’s UD-3900 is a DisplayLink dock to investigate for a compatible USB-A or USB-C host connection.
This USB-C dock is an option to check for a two-monitor desk setup when the laptop supports the required native video output; its presence here does not establish compatibility with your laptop.

For two external monitors, check that your laptop’s USB-C port carries video and supports both displays at the settings you intend to use. The product name specifies dual HDMI 4K and 100W power-delivery pass-through; compare the laptop’s charging requirement and confirm whether the necessary external power adapter is included.
Find its exact model, operating system, video-capable ports and manufacturer-stated external-display limit. Note each monitor’s intended resolution, refresh rate and input connection, plus the laptop’s charging requirement. Apple Support says a hub or daisy chain does not increase a MacBook Air model’s maximum number of external displays.
No. The laptop must support the required video output and number of external displays; the dock’s advertised maximum does not establish what that laptop can deliver. Check the exact laptop model and dock combination at your intended resolution and refresh rate.
It may be able to use a DisplayLink dock that explicitly supports a USB-A host connection and its installed operating system. Targus UK lists a USB-A legacy host adapter and dual HD output for the DisplayLink-based DOCK116GLZ. Check the exact dock’s driver requirements and output modes before choosing it.
Do not assume it will. DisplayLink Support says some protected content, including video from Netflix, Disney+ and Amazon Prime, may not play while DisplayLink screens are connected to a Mac. If streaming is important to your desk setup, consider a native display-output route where your Mac supports the required monitors.
