Desk-based document workers
If documents, spreadsheets, study materials or calls compete for space on one display, a monitor that fits the desk and can be positioned for regular use may be more useful than one designed to travel.
Who needs a second screen?
Flexible-location laptop users
If the working spot changes between rooms or locations, consider how easily the second screen can be carried, connected and supported wherever it is used.
Home creative and casual gaming users
If the same workspace is used for visual projects or games, compare the stated resolution, colour space and refresh rate with those tasks and with the computer’s output capabilities.
What matters when choosing?
Decide whether the screen will stay on a desk or move around, then check the connection and the display features your work calls for.
| Concern | What to check | Who this matters to |
|---|---|---|
| Room for documents | Measure the desk and the monitor with its stand; compare screen size and resolution for the windows you use together. | If I keep documents, reference material or meetings open side by side, visible workspace comes first. About 42% of consumers put that need ahead of the other buying concerns. |
| Connection and charging | Confirm the computer’s video output and the monitor’s matching input. For USB-C charging, compare stated power delivery with the laptop’s requirement. | A one-cable desk setup matters little to me unless the picture works and my laptop receives enough power. Getting the connection and charging right is the primary concern for about 25% of consumers. |
| Portability and desk space | Check the screen’s weight, its support and power arrangement, and whether it can be positioned on each surface where you plan to use it. | If I move between work spots or put the screen away afterwards, carrying and setting it up matter more than a permanent large display. About 17% of consumers prioritise that flexibility. |
| Visual tasks and games | Match resolution and refresh rate to the computer’s output; for creative work, check the explicitly stated colour space. | For visual projects or games, I would choose display characteristics for those tasks rather than for documents alone. Those specifications come first for about 16% of consumers. |
What should you check before buying?
-
Assuming every USB-C port carries video
USB-C describes the connector, not every function it supports. Which? notes that only some USB-C connections carry DisplayPort video; ASUS likewise says portable-monitor display use requires video functionality on the computer and monitor ports.
Check the exact computer model and port specification. If its USB-C video output is uncertain, check whether the monitor has an HDMI input or whether a compatible adapter route is available.

Expecting any USB-C monitor to charge a laptop
Charging output varies by model: LG specifies up to 15W for the 27U631A-B, while Dell specifies up to 100W for the P2426HE. Neither figure establishes what another monitor supplies or what a particular laptop needs.
Compare the monitor’s stated power delivery with the laptop’s charging requirements before planning to use one cable.
You may need to keep the laptop’s own charger connected.

Choosing screen size without checking its position
A screen can fit the available width yet still be difficult to place at a comfortable height. The Health and Safety Executive advises positioning the top of the screen around eye level and the screen about an arm’s length away.
Measure the desk, including space for the stand, and check whether the display can be raised or mounted to suit your working position.
A suitable riser or monitor arm may be needed if the supplied arrangement cannot reach that position.
-
Choosing visual specifications without matching the task
Refresh rate and stated colour coverage answer different needs. Manufacturer colour claims for a particular model do not establish calibration accuracy for professional colour-critical work.
Start with the tasks you actually do, then check the relevant specifications and whether your computer can drive the intended resolution and refresh rate.
Brands to consider
Dell
Dell’s P2426HE is an example of a fixed USB-C hub monitor for a desk-based setup.
- Dell specifies a 23.8-inch FHD IPS screen, height, pivot, swivel and tilt adjustment, and up to 100W USB-C power delivery for this model.
- Check that the laptop supports video through its USB-C port and accepts the available charging output.
LG
LG’s 27U631A-B illustrates a fixed QHD screen with USB-C display connectivity.
- LG specifies a 27-inch QHD IPS panel, 100Hz refresh rate and typical 99% sRGB coverage for this model.
- Its stated USB-C power delivery is up to 15W; check laptop charging needs separately.
ASUS
ASUS ZenScreen models offer portable-screen options for laptop setups that move between locations.
- ASUS specifies dual USB-C connections, mini-HDMI, a kickstand and a stated weight of 0.92 kg for the MB16AHG.
- Check computer-side USB-C video capability; the connector alone does not establish it.
BenQ
BenQ’s PD2732U is aimed at creative workflows where specified colour space and connectivity matter.
- BenQ lists 4K resolution, Adobe RGB support and Thunderbolt 4 with 90W power delivery for this model.
- These manufacturer specifications do not establish that such features are needed for routine documents or replace assessment of professional calibration requirements.
Joybuy monitors for different setups

ASUS ZenScreen MB249C IPS USB-C
Consider this ZenScreen when the second display needs to be repositioned rather than left permanently on one desk. Its name identifies an IPS model with USB-C; check that your computer can send video through that connection and that any intended USB-C charging meets its needs. If carrying weight matters, confirm the supplied configuration’s weight before buying.

ASUS ProArt PA278CV IPS WQHD
This fixed-desk option is worth considering when document space and screen positioning take priority over portability. The product name specifies IPS and WQHD. Confirm its dimensions against your desk and check USB-C video compatibility and charging output before relying on a one-cable laptop setup.

Lenovo L32p-30 31.5-inch 4K UHD IPS USB-C monitor
Consider this fixed screen if a 31.5-inch display fits your desk and your computer can output the 4K UHD setting you want to use. The product name also specifies IPS and USB-C. Confirm the exact model identifier and its USB-C video and charging capabilities before planning a one-cable setup.

AOC Q32V4 31.5-inch monitor
This is a fixed-screen option to assess if your computer uses HDMI or DisplayPort and you have room for a 31.5-inch monitor. Confirm the intended resolution, the dimensions with its stand and the available adjustments before choosing it for prolonged desk work.

ASUS ZenScreen MB166CR FHD
Consider this portable second screen if you need to move it with a laptop or put it away between sessions. The product name specifies FHD. Check that the laptop outputs display video through USB-C, and confirm how the screen will be supported at each working location.
Questions about second screens
Will any USB-C laptop port connect to a USB-C monitor?
No. The laptop port must support a compatible video-output method, such as DisplayPort Alt Mode, and the monitor must accept it. ASUS advises checking video functionality on both devices for USB-C portable-monitor use.
Can a USB-C monitor charge my laptop as well as show a picture?
Only if the connection supports video and the monitor supplies suitable power for your laptop. Compare the exact models: LG specifies up to 15W for its 27U631A-B, while Dell specifies up to 100W for its P2426HE.
Is a portable monitor suitable for working from home?
It can suit work that moves between locations or a screen that must be packed away. For longer sessions at a desk, also check whether its stand lets you place the screen comfortably; the Health and Safety Executive advises a screen position with its top around eye level and the display about an arm’s length away.
How should I position a second screen for regular desk work?
Arrange the screen so you can view it comfortably without keeping your laptop display too low. The Health and Safety Executive advises putting the top of the screen around eye level and roughly an arm’s length away; for prolonged laptop use, it advises a separate keyboard and mouse so the display can be raised.
