Start with your laptop’s supported video outputs and external-display limit, then choose a monitor that fits both those capabilities and your desk. For one extra screen, a direct connection may be enough; USB-C can combine video and charging only when the laptop, cable and monitor support the required functions. Consider a dock when you also need connections for peripherals or a wired network, but check the laptop’s display limit before buying one.
If documents, messages and other work windows compete for space on your laptop, an external monitor gives you another place to arrange them. Check the laptop’s video output and the monitor’s input before choosing a cable or adapter.
A USB-C monitor may suit a desk where you want video, laptop charging and connections for other devices through one cable. Confirm each function on the exact laptop and monitor; the USB-C connector alone does not establish what it can carry.
Desk depth, stand adjustment and mounting options matter when there is little room to place the display. The Health and Safety Executive advises positioning the top of the screen around eye level and the screen about an arm’s length away.
Check the laptop first, then compare the monitor and any cable, adapter or dock needed to connect it.
| Priority | What to check | Your needs |
|---|---|---|
| Video connection | Compare the laptop’s supported video output with the monitor’s HDMI, DisplayPort or USB-C input. If you need an adapter, confirm that it carries the required display signal. | I want to connect one work screen without buying an adapter that cannot carry video from my laptop. |
| USB-C charging | Confirm USB-C video support on the laptop, video capability in the cable and the monitor’s Power Delivery rating. Compare that rating with the laptop’s charging requirement. | One cable would make my desk simpler, provided it can both display my work and supply the power my laptop needs. |
| Screen space | Compare resolution alongside screen size and desk dimensions. Check that the laptop supports the intended resolution and refresh rate on the chosen connection; Apple Support UK notes that these settings affect supported display configurations on Macs. | I need room for documents and communication windows, but the screen still has to fit my desk and work with my laptop. |
| Screen position | Check stand adjustment, desk depth and, if considering an arm, the exact monitor’s mounting specification. The Health and Safety Executive advises a screen top around eye level and a viewing distance of about an arm’s length. | My display needs to sit at a workable height and distance without crowding the keyboard and mouse. |
| Extra connections | Decide whether a direct cable is sufficient or whether a dock needs to add USB devices, Ethernet or further display outputs. Verify the laptop’s external-display limit: Microsoft Support says an HDMI splitter duplicates a signal rather than creating independent extended screens. | If I’m adding peripherals as well as a monitor, I want a connection setup that handles those devices without assuming a dock can extend any laptop’s display capacity. |
USB-C ports and monitors have different capabilities. BenQ’s specification for the GW2490C, for example, lists USB-C display and data connectivity but no laptop Power Delivery.
Check the laptop’s display-output and charging specifications, the cable’s video capability and the exact monitor’s USB-C functions before ordering.
A different cable or adapter may be needed if the intended connection cannot carry the required signal.
Microsoft Support says a splitter duplicates one signal rather than creating two independent extended displays. Apple Support UK says the number of supported Mac displays depends on the model, resolution and refresh rate.
Check the laptop’s supported external-display count before selecting equipment for multiple screens; for a single screen, see whether a direct cable or simple adapter will do.
A larger display still needs enough desk depth and a suitable position. Size and resolution together also affect how the workspace and text appear.
Measure the available desk area, compare screen size with resolution, and check stand adjustment or mounting compatibility if the screen cannot otherwise be positioned well.
Placing the laptop screen higher changes where its built-in keyboard and trackpad sit. The Health and Safety Executive advises a separate keyboard and mouse for prolonged laptop use when the screen is raised.
Plan the positions of the monitor, laptop, keyboard and mouse together before settling on a stand or arm.
Compare exact models rather than assuming every monitor in a brand’s range has the same connections or charging capability.
Dell’s P2425HE and P2425DE are USB-C hub monitors with different stated resolutions.
The ThinkVision P24h-30 is a 23.8-inch QHD monitor with desk-connectivity features.
The LG 27BA750-B is a 27-inch Full HD option for a desk where screen size and USB-C connectivity are priorities.
The GW2490C is an option to examine if you plan to keep using a separate laptop charger.
These external monitors offer different screen formats for adding a display to a laptop desk. Match the exact model’s connections and positioning options to your laptop and workspace before choosing.

Consider this model if you want a USB-C monitor whose position you can adapt to your desk. Check your laptop’s USB-C video and charging requirements against the exact monitor specification, and confirm which mounting parts and power adapter come with the UK variant.

The WUXGA screen format is worth comparing if you work with documents and want to assess vertical workspace as well as screen size. Before planning a USB-C connection, check laptop video support and charging requirements; also confirm which display cables are included with the UK package.

Compare this QHD model if you want a work screen that fits your available desk space. Confirm that the laptop supports the intended resolution and connection; if you intend to use USB-C for charging too, compare power specifications and check the UK package contents for the cable you need.

The 22-inch Full HD format is one to consider where desk space is limited. Check the laptop’s supported video output against this model’s inputs and confirm the stand adjustments you need; do not plan on USB-C laptop charging without checking the exact connection specification.

Compare this WQHD model when you have room for a larger work display and can position it at a suitable distance. Verify the laptop’s intended video mode and the monitor’s USB-C Power Delivery rating against the laptop’s charging requirement before relying on monitor charging.
Check the exact laptop model’s display-output specification, not just the shape of its USB-C socket. Apple Support UK says a display adapter for a compatible Mac port must support the relevant DisplayPort Alt Mode or Thunderbolt standard; check the monitor and cable specifications as well.
A direct cable or suitable adapter may be enough for one additional screen; consider a dock when the same laptop connection also needs to serve peripherals, Ethernet or other supported display outputs. Check the laptop’s display limit first: Microsoft Support says a splitter duplicates a signal rather than creating an independent extended screen.
Check the instructions for your exact laptop and operating system before planning a closed-lid desk setup. Apple Support UK says supported external-display configurations for MacBook Pro depend on the model and on display resolution and refresh rate, including when connected displays are used with the lid closed.
The Health and Safety Executive says employers must assess workstations for workers who use display screen equipment daily for continuous periods of an hour or more. If that describes your work, consider the monitor’s position alongside the laptop, keyboard and mouse as part of the workstation.
