An external monitor is worth considering when your laptop screen limits how comfortably you can keep documents, calls and other work visible. A fixed screen suits a desk that stays set up; choose a USB-C connection for video and charging only after checking the laptop port and power requirements. For a shared or temporary workspace, a portable screen is easier to put away, but offers less display area and still needs a compatible connection.
If documents, calls and other windows compete for space on your laptop, a fixed monitor may give you a more workable display area. Check that the screen and stand fit alongside the laptop and anything else you use on the desk.
A USB-C monitor may combine display, charging and peripheral connections, but only if the particular laptop port, monitor and cable support the functions you need. The shape of the socket alone does not settle compatibility.
A portable display is worth considering when you cannot leave a full-size monitor assembled. Compare its packed size and connection requirements with the space available when you work.
Choose when: Your desk stays set up and your laptop has a matching video output or a confirmed compatible adaptor.
Allow for: Laptop charging and peripheral connections may need their own cables or a separate hub.
Choose when: Your laptop port supports monitor video and the monitor can provide the charging power your laptop requires.
Check first: Which? notes that USB-C carries DisplayPort video only when the particular connection supports it.
Choose when: You work at a shared table or changing location and need to put the extra screen away.
Allow for: A smaller display area and model-specific laptop connection requirements.
| Priority | What to check | Your needs |
|---|---|---|
| Display space | Compare screen size with the usable work surface and the windows you keep open. Check the exact model's native resolution and stand adjustments. | I want to keep documents and calls visible without constantly switching windows, but the screen must still fit my desk. |
| Video connection | Match the laptop's video output to the monitor input and cable. Which? explains that HDMI carries video and audio, while USB-C video depends on the particular port's capabilities. | My laptop needs a confirmed route to the screen, whether that is a direct connection or a compatible adaptor or dock. |
| Charging and peripherals | For USB-C charging, compare the monitor's stated Power Delivery output with the laptop's charging requirement. Check for the USB or Ethernet ports you would actually use. | Fewer cables would help at my regular desk, provided the monitor can handle the connections and charging I need. |
| Putting it away | Compare a portable screen's dimensions, weight and setup with where you will store it. Confirm the exact monitor's required video mode against the laptop port. | I work at a shared table or move between spaces, so leaving a full-size display in place is impractical. |
Which? says DisplayPort video over USB-C depends on the connection. Lenovo, for example, specifies DP 1.2 Alt Mode and PD 2.0 for one-plug display use with the ThinkVision M14.
Check the laptop's port specification, the monitor's required video mode and the cable before ordering.
Charging output varies by model. The Dell S2722DC is listed at 65 W and the Dell P2425HE at up to 90 W; neither figure establishes what a different laptop requires.
Compare the monitor's stated output with your laptop manufacturer's charging requirement.
If the monitor cannot meet that requirement, you may need to keep using the laptop charger.
Which? distinguishes smaller screens for limited spaces from larger monitors suited to home offices. Screen diagonal alone does not tell you how much room the stand occupies.
Measure the usable width and depth, then check the stand dimensions and adjustment range of the exact model.
For UK workers using display screen equipment daily for continuous periods of an hour or more, the Health and Safety Executive says employers must assess the workstation. Its home-working guidance says the DSE Regulations can apply to permanent, long-term and routine hybrid home working.
If this applies to your work, use your employer's assessment process. The assessment considers the whole workstation, work conditions, job and individual requirements, not just the screen.
Dell has fixed-desk USB-C models with different screen and connection options; compare the exact model rather than assuming the features apply across its range.
The ThinkVision portable models are relevant when an extra laptop screen must move or be put away.
BenQ lists compact USB-C monitors with work-oriented connections and stand options, which differ by model.
These options include screens for a regular desk and displays to consider for a changing workspace. Choose by desk fit and laptop connection, not by screen size alone.

Consider this ZenScreen for a temporary workspace where the extra display needs to be put away. For the listed USB-C display connection, check that your laptop supports DisplayPort Alt Mode; do not plan on an HDMI connection for this model.

This fixed-screen option is for a desk that stays set up. If you intend to use USB-C for both video and charging, confirm your laptop's video output and charging requirement against the monitor's stated capabilities.

The stated 22-inch size makes this a fixed-screen option to assess for a smaller desk. Match your laptop's video output to the monitor's HDMI or DisplayPort connection, and check the stand footprint before deciding it fits.

Consider this larger fixed-screen option if you have room for a permanent setup. Confirm the exact screen diagonal and stand footprint before judging desk fit, and check that your laptop can connect to its HDMI or DisplayPort input.

This ZenScreen is an option for a workspace that changes, provided its setup suits the available surface. Check its actual weight if you will carry it regularly. For USB-C use, confirm laptop DisplayPort Alt Mode support and compare the monitor's stated charging output with your laptop's requirement.
Not necessarily. Consider one if the laptop screen limits how you keep documents, calls and other work visible; then decide whether you can leave a fixed screen in place or need one that can be put away. Which? distinguishes smaller monitors for limited spaces from larger screens suited to home offices.
No. Which? explains that USB-C carries DisplayPort video only when the connection supports it. Check the exact laptop port and monitor requirements: Lenovo, for example, specifies DP 1.2 Alt Mode and PD 2.0 for one-plug display use with the ThinkVision M14.
Yes, if the particular laptop port, cable and monitor support the required video and power functions, and the monitor's output meets the laptop's charging requirement. 65 W Power Delivery is listed for the Dell S2722DC and up to 90 W for the P2425HE; those figures apply to those models, not to USB-C monitors generally.
Yes, if the laptop and monitor have compatible HDMI connections. Which? describes HDMI as a common way to carry digital video and audio to a screen. Plan separately for laptop charging and any USB peripherals or Ethernet connection you need.
For workers using display screen equipment daily for continuous periods of an hour or more, the Health and Safety Executive says employers must assess the workstation. Its guidance says the DSE Regulations can apply to permanent, long-term and routine hybrid home working; an assessment considers the whole workstation and does not automatically mean every worker needs a monitor.
