Choose a dock or adapter that explicitly supports two independently extended displays and has a downstream USB port for your printer; an ordinary USB data hub or HDMI splitter does not establish that capability. A native USB-C video dock suits a laptop that supports the required display arrangement, while a DisplayLink dock offers another route for compatible USB-A, USB-C and Mac setups but requires software support. For occasional use, a compact adapter may suffice if each screen’s stated output limit and the available USB ports meet your needs.
If you want different applications on each external screen, check for independent display support as well as a downstream USB port for the printer. Microsoft Support distinguishes an extended display arrangement from a splitter that duplicates one signal.
A DisplayLink dock may suit a desk shared by USB-A and USB-C laptops, or a compatible Mac whose native display support does not meet your needs. Check the exact laptop and operating system: Apple says Mac display support varies by model, and DisplayLink setup on macOS requires software and permission.
A compact adapter can put video outputs and a printer port in one device. Compare the limit for each screen separately: StarTech.com lists different resolution and refresh-rate limits for the two HDMI outputs on its 167B-USBC-MULTIPORT adapter.
Choose when: Your laptop’s USB-C video output and graphics hardware support the two extended screens you want.
Trade-off: The dock cannot add native display capability the laptop lacks. StarTech.com specifies that dual 4K at 60Hz on its DK31C2DHSPDUE requires a DP 1.4 Alt Mode HBR3 host with DSC enabled.
Choose when: You need a compatible route for a laptop without the required native dual-display support, or you must accommodate USB-A and USB-C hosts.
Trade-off: DisplayLink needs compatible software. DisplayLink Support says macOS users must grant Screen Recording permission to DisplayLink Manager for its displays to work.
Choose when: You want connections for occasional desk use or travel and can work within the adapter’s individual screen limits.
Trade-off: Outputs need not have equal limits: StarTech.com lists up to 4K at 30Hz on one output and 1080p at 60Hz on the other for its 167B-USBC-MULTIPORT.
| Concern | What to check | Who this matters to |
|---|---|---|
| Two independent screens | Confirm explicit support for two extended displays, then match each output’s resolution and refresh rate to its monitor. | I need different work on each screen rather than the same image twice; around 50% of consumers put independent displays first. |
| Laptop and software compatibility | Check the exact host ports and supported display count. For DisplayLink, check operating-system support and whether you can install its software. | When I switch laptops or use a Mac, I need the connection to work with that specific computer; roughly 30% of consumers make cross-device compatibility their main concern. |
| Portability and printer ports | Count the downstream ports needed at once, including the printer connection, and check the adapter’s size and each video output limit. | I would rather carry one compact adapter for my printer and screens, even if its display limits are modest; about 20% of consumers prioritise that practical port mix. |
A splitter duplicates a video signal; it does not by itself create two independently extended screens, as Microsoft Support explains.
Look for explicit dual-extended-display support and confirm that the laptop can drive the intended number of external screens.
The USB-C connector alone does not establish the laptop’s video capability or the display modes available through a particular dock.
Check the laptop manufacturer’s specifications against the dock’s host requirements, including DisplayPort Alt Mode and DSC where the stated display mode requires them.
A compatible DisplayLink dock still needs its software to be usable for the intended displays. On macOS, DisplayLink Manager also requires Screen Recording permission, according to DisplayLink Support.
Check operating-system support and whether you are allowed to install the software, particularly on a managed work laptop.
Two HDMI outputs can have different limits. StarTech.com lists up to 4K at 30Hz on one output and 1080p at 60Hz on the other for its compact 167B-USBC-MULTIPORT adapter.
Note the resolution and refresh rate required for each monitor, then compare them with the specification for each output.
Its compact adapters, native USB-C docks and DisplayLink docks provide different connection routes for this setup.
Its SD4781P EQ is a reference point for a fixed desk shared by USB-C and USB-A laptops.
Its UD-3900C is a DisplayLink model to examine when native dual-display support is a concern.
This USB-C multiport adapter brings together video outputs and downstream USB ports for a printer-and-two-screen setup. Check your laptop and both monitors against its display requirements before choosing it.

Consider this adapter if you need USB ports alongside two extended screens: its product description claims support for three independent displays, but check the required laptop video capability and each output’s resolution and refresh-rate limit against your setup.
The listed connections include two USB 3.0 and two USB 2.0 ports. Confirm that your printer can use the appropriate connection, and check any laptop-charging requirement separately.
A USB data hub can provide a printer port, but it does not automatically provide two independent video outputs. Choose a dock or adapter that explicitly supports two extended screens, and check the laptop’s display capability; Microsoft Support notes that a display splitter duplicates a signal instead.
Check the exact laptop model’s external-display count and USB-C video specifications against the dock’s host requirements. For a Mac, Apple advises checking the model’s Display Support or Video Support specifications because the supported number of external displays varies by model.
Yes, a DisplayLink dock needs compatible DisplayLink software for its video function. DisplayLink Support says macOS users must also grant Screen Recording permission to DisplayLink Manager for extended or mirrored displays to work.
Only if the exact dock and the host connection provide suitable laptop charging. Kensington specifies up to 100W Power Delivery for its SD4781P EQ, but says USB-A host devices need a separate power source; check both the dock’s charging specification and your laptop’s requirements.
