Laptop users adding one regular work screen
If documents, email or meetings compete for space on your laptop display, consider a second screen that fits alongside the laptop on your desk.
Who is this setup for?
People who want one cable at their desk
A USB-C hub monitor is worth considering if your laptop’s USB-C port carries video and the monitor’s charging output suits the laptop.
Users with several desk connections
If you need wired networking, USB accessories or multiple external displays, compare a hub monitor with a separate dock against the exact laptop’s supported connections and display limit.
What should you check before buying?
Choose how the monitor will connect, then check the screen’s physical fit and whether you need charging or other desk connections through the same cable.
Direct monitor connection
Choose when: You need one extra screen and your laptop has a compatible video output.
Trade-off: The monitor connection does not itself add laptop charging, Ethernet or USB peripherals.
USB-C hub monitor
Choose when: Your laptop supports video over USB-C and you want the monitor to handle charging or desk peripherals too.
Trade-off: Charging output and cable capabilities vary by product, so the intended one-cable setup needs checking.
Separate dock and monitor
Choose when: You need additional connections or a multi-display arrangement confirmed for your laptop.
Trade-off: The dock adds equipment and another compatibility check; some setups also need software permissions.
| Priority | What to check | Your needs |
|---|---|---|
| Video connection | Match the laptop’s video output to the monitor input. For USB-C video, check the exact port and cable capabilities; Microsoft Support notes that USB-C-compatible cables do not all support every feature. | I want the second screen to connect without relying on the shape of a port as proof that it carries video. |
| Display limits | Check the laptop’s supported number of external displays and the intended resolution and refresh rate. Apple Support says a hub or daisy-chain does not increase a Mac’s maximum supported display count. | If I might add another screen later, I need to know what my exact laptop model can run before choosing a dock or daisy-chain setup. |
| Desk fit | Measure the space for the monitor and laptop, including the stand footprint. Check the height and angle adjustments you need; the Health and Safety Executive advises considering the whole workstation, not equipment in isolation. | There needs to be room for the display and a workable screen position, not just space for its advertised diagonal size. |
| Charging and peripherals | For a USB-C hub monitor, compare its stated power delivery with the laptop’s charging requirements and check its actual peripheral connections. If considering a DisplayLink dock on macOS, check app and permission requirements. | I would like fewer separate desk connections, but only if the chosen monitor or dock handles the devices and charging I use. |
Which mistakes are worth avoiding?
-
Assuming every USB-C port carries video
A monitor or adapter can have the right-shaped connector without receiving a video signal. Microsoft Support also cautions that USB-C cables do not all support the same features.
Check the exact laptop port’s video capability, then match the cable or adapter to that output and the monitor input.
A different compatible cable or connection route may be needed.
-
Expecting a dock to override the laptop’s display limit
Apple Support says a hub or daisy-chain does not raise a Mac’s maximum supported display count. The intended number of screens must fit the computer’s own limits.
Confirm the exact laptop model’s supported display count, resolution and refresh rate before choosing a multi-output dock or DisplayPort-out monitor.
-
Choosing by screen size alone
A second display still needs to fit the desk and sit in a usable position. The Health and Safety Executive advises looking at the whole workstation and the work being done.
Measure the available desk space and check the stand’s positioning options before settling on a screen size.
-
Overlooking DisplayLink setup on a Mac
DisplayLink Support says DisplayLink Manager needs Screen Recording permission on macOS to operate with DisplayLink displays.
Check whether the proposed dock uses DisplayLink and whether your work laptop permits the required app and permission.
Allow time to install and configure the app if this connection route is suitable for your laptop.
Which monitor lines are relevant?
Dell
Dell’s P2425HE is an example of a USB-C hub monitor for a regular laptop desk setup, rather than a description of every Dell display.
- Dell UK specifies a Full HD display and power delivery of up to 90W for the P2425HE.
- Check the laptop’s USB-C video capability and charging requirements against this exact model.
LG
LG’s 27BA750-B is a 27-inch Full HD option for comparing a larger screen with a USB-C connection.
- LG UK states that its USB-C connection carries display and data and provides charging up to 65W.
- Compare that stated charging ceiling with the laptop’s requirements, and check that a 27-inch screen fits the desk.
Lenovo ThinkVision
The ThinkVision T24m-29 is relevant if you are considering a USB-C monitor as part of a possible multi-screen desk.
- Lenovo UK describes DisplayPort-out daisy-chaining on the T24m-29.
- Daisy-chaining still depends on the connected computer’s supported display configuration.
Joybuy monitors for a direct connection
These monitors are options to consider for adding a work screen to a laptop through a compatible direct video connection. Check each monitor’s inputs against your laptop before choosing.

Samsung S40GD LS22D400GAUXXU 22-inch Full HD monitor
The stated 22-inch size is worth considering where the laptop and second screen must share a limited desk. Check the monitor’s inputs and your laptop’s supported video output before ordering.

AOC Q32V4 31.5-inch 2K IPS monitor
The stated 31.5-inch screen calls for a desk-space check before use alongside a laptop. Confirm the connection and screen-positioning options you need against the monitor and your exact laptop.
Common questions
Does a USB-C port guarantee that my laptop can use a USB-C monitor?
No. Check the exact laptop port for video-output support and choose a cable that supports the connection you need. Microsoft Support notes that USB-C-compatible cables do not all provide every feature.
Will a dock let any MacBook run more external displays?
No. Apple Support says a hub or daisy-chain does not increase a Mac’s maximum supported display count. Check your exact Mac model and intended display configuration before selecting a multi-display dock.
Do I need a dock for just one extra screen?
A direct monitor connection is a reasonable choice if your laptop has a compatible video output and you do not need charging or extra peripherals through the same connection. Consider a dock when its additional connections meet a specific need and are compatible with your laptop.
What should I check before using a DisplayLink dock on macOS?
Check that the work laptop permits the required software and permissions. DisplayLink Support says DisplayLink Manager needs Screen Recording permission on macOS to operate with DisplayLink displays.
