Fixed-desk multitaskers
If documents, spreadsheets and calls share one laptop screen, a monitor with suitable connections and a position you can adjust is worth considering. Which? identifies ports and ergonomic adjustment as monitor-buying factors.
Who needs an extra screen?
People with shared or limited desk space
A display that can be moved, stored or mounted differently may suit a desk that cannot accommodate a permanent second screen. Check its weight, mounting arrangement and connection to your laptop before choosing a portable model.
People doing detailed visual work
Photo, video or other detailed tasks may make resolution and stated colour coverage more important. Which? distinguishes monitors for photo and video editing; check that your laptop can drive the resolution you choose.
What matters when choosing?
Decide where the screen will live, then check how it will connect. USB-C connectivity can be useful with either desk arrangement, but the socket alone does not establish video or charging compatibility.
Fixed monitor
Choose when: The screen can stay at one desk for work or study, and you can position it to suit the workspace.
Trade-off: It needs a permanent place and is less convenient to move between rooms.
Portable monitor
Choose when: You need to move or put away the second screen, or a supported clamp, hook or kickstand arrangement suits your space.
Trade-off: Check the actual carrying weight and video connection; portable does not necessarily mean light or compatible with one cable.
| Concern | What to check | Who this matters to |
|---|---|---|
| Desk comfort and space | Measure usable desk space and check the stand footprint and adjustments, or whether a suitable mount can be used. | If I work at one desk for long sessions, I need the extra screen to fit where I can position it comfortably without troublesome glare. Around 27% of consumers put desk comfort and space first. |
| Connection and charging | Check the laptop's documented video outputs and, for one-cable use, its USB-C video and charging support against the monitor, cable or dock. | I want the display to work with my existing laptop, and I may want to charge it without another desk cable. Connection and charging are the primary concern for around 33% of consumers. |
| Moving or storing the screen | Compare screen dimensions, stated weight and placement options with how often you will move it. | When I share a desk or move between rooms, I need a second screen that I can place and put away practically. Around 20% of consumers prioritise that flexibility. |
| Visual detail | Compare resolution and stated colour specifications with your tasks, and confirm the laptop supports the intended output. | For detailed imagery or video work, I need to judge whether the display specifications suit my workflow rather than choosing on size alone. That is the leading need for around 20% of consumers. |
Mistakes to avoid
-
Assuming every USB-C port carries video
A USB-C connector does not establish that the laptop can output a picture through it. Lenovo, for example, specifies USB-C DP1.2 Alt Mode and PD2.0 support for the ThinkVision M14.
Check the exact laptop model's video-output specification before buying a USB-C-only display or dock. If the laptop has HDMI, check whether the monitor offers a compatible input.
-
Assuming monitor charging suits every laptop
The ASUS ZenScreen MB249C specifies 60W USB-C power delivery, while Dell states up to 90W for the P2425HE. Neither figure alone establishes that a particular laptop can charge as required.
Confirm that your laptop accepts USB-C charging and compare its requirements with the display or dock's stated output.
You may still need to use the laptop's original charger.
-
Choosing by screen diagonal alone
A screen that does not fit the usable desk area or sit in a suitable position may be awkward to use. Which? flags ergonomic adjustment as a buying factor, and the Health and Safety Executive advises attention to screen position and glare.
Measure the space and check the stand footprint, adjustment range and any mounting arrangement before settling on a size.
-
Treating every portable monitor as easy to carry
Portable models differ substantially in size and stated weight: ASUS specifies 2.8 kg for the ZenScreen MB249C, while Lenovo specifies 598 g for the ThinkVision M14.
If you move the screen frequently, weigh carrying convenience against the screen area you need; for occasional moves around the home, placement options may matter more.
Monitor brands and models to consider
Dell
The P2425HE is a fixed-desk USB-C hub monitor to consider where laptop connectivity and screen adjustment matter.
- Dell specifies a 23.8-inch FHD IPS panel, height, pivot, tilt and swivel adjustment, RJ45 Ethernet and up to 90W power delivery for this model.
- Check whether FHD at this size provides enough detail for your work and whether your laptop supports the intended USB-C setup.
LG
The named LG models address different fixed-desk needs, from integrated call equipment to a higher-resolution display.
- LG specifies a webcam, microphone, speakers, RJ45 and USB-C 90W for the 27BA850-B; its 27U730A-B has a 27-inch 4K IPS panel, DCI-P3 90% typical coverage and stated USB-C 90W.
- These features are model-specific. Match the display and connection requirements to your laptop and tasks.
ASUS
The ZenScreen MB249C offers placement options for a second screen that may need to move around a home workspace.
- ASUS specifies a 23.8-inch FHD IPS screen with a kickstand, C-clamp arm, partition hook, HDMI and USB-C with 60W power delivery.
- Its stated 2.8 kg weight deserves consideration if you intend to carry the screen frequently; check that its connections and mounting options suit your setup.
Lenovo
The ThinkVision M14 is a compact portable option for a laptop with the required USB-C capabilities.
- Lenovo specifies a 14-inch FHD IPS screen weighing 598 g, with two USB-C ports and power pass-through.
- Lenovo requires a notebook USB-C port supporting DP1.2 Alt Mode and PD2.0; a USB-C socket by itself is not enough.
Joybuy monitors for a fixed desk
These monitors are options for adding screen space to a laptop at a permanent desk, particularly where display detail or screen positioning matters. Check your laptop's outputs and the available desk space before choosing; a USB-C label alone does not establish one-cable video and charging.

Common questions
How do I know whether my laptop can use a USB-C monitor?
Check the exact laptop model's specifications or manual for documented USB-C display output, such as DisplayPort Alt Mode or a supported Thunderbolt connection. The connector shape alone does not prove that it carries video; Lenovo, for example, specifies USB-C DP1.2 Alt Mode and PD2.0 for the ThinkVision M14.
Can a USB-C monitor replace my laptop charger?
It can do so only if the laptop supports USB-C charging and the monitor supplies compatible power. Compare the laptop maker's requirements with the particular monitor's power-delivery rating before planning a one-cable desk setup.
Should I replace my laptop with an all-in-one desktop instead?
If the laptop otherwise meets your needs and has a compatible video output, an external monitor addresses the need for more screen space without replacing the computer. Consider an all-in-one as a separate choice when the computer itself needs replacing and a permanent desktop setup suits you.
