For a very small desk, consider a compact 14-inch, 16:10 screen with an adjustable stand, such as the Lenovo ThinkVision M14d. If you have room for a larger documentation view, the 16-inch LG +view 16MR70 offers another option; for either model, check your laptop’s USB-C video output and power capability before buying.
Who needs a portable second screen?
Developers with limited desk space
If you keep code on one screen and documentation on another, the second monitor’s footprint and viewing angle may matter as much as its diagonal size. Lenovo UK lists an adjustable stand on its 14-inch ThinkVision M14d.
People working from long reference documents
A 16:10 display may appeal if you regularly read documentation or tickets beside an editor. Lenovo UK specifies a 2240 × 1400 panel for the ThinkVision M14d, while LG UK specifies 2560 × 1600 for its larger +view 16MR70.
People planning a USB-C setup
If you want the laptop to drive a portable display through USB-C, check the functions of the particular port before choosing a monitor. ASUS explains that a USB-C connector does not, by itself, establish video-output support.
What should you check first?
Decide whether reading space, physical fit or a dependable laptop connection is the constraint most likely to shape your code-and-documentation setup.
Compact 14-inch, 16:10 screen
Choose it when: the monitor must sit close beside your laptop and an adjustable stand matters. Lenovo UK lists a 14-inch, 2240 × 1400 panel and integrated adjustment for the ThinkVision M14d.
Trade-off: its physical display area is smaller than that of a 16-inch screen.
Larger 16-inch, 16:10 screen
Choose it when: you can accommodate a wider display and want more physical space for documentation. LG UK lists a 16-inch, 2560 × 1600 panel for the +view 16MR70.
Trade-off: allow room for the larger screen, and check its laptop video and power requirements.
15.6-inch Full HD screen
Choose it when: a 15.6-inch display fits and 1920 × 1080 is sufficient for your secondary view. ASUS lists those specifications for the ZenScreen MB16ACE.
Trade-off: that model’s 16:9 panel has fewer vertical pixels than the 16:10 models above, and its specified design has no height adjustment.

What to check |
Who this matters to |
| Text space |
Compare resolution and aspect ratio; confirm that the resulting screen size will fit beside your laptop. |
I want code and reference pages visible without repeatedly resizing them. Around 46% of consumers might make text space their primary concern. |
| Desk fit |
Measure the available width and depth, then check the stand’s footprint, tilt and height adjustment. |
My second screen has to sit beside the laptop without taking over the desk. Roughly 36% of consumers might put positioning first. |
| Connection and power |
Check the laptop’s USB-C video output, the monitor’s power requirements and whether the intended cable and charger are suitable. |
I need the display to show a picture and receive enough power from my actual setup. About 18% of consumers might prioritise connection and power certainty. |
Mistakes to avoid
-
Assuming every USB-C port outputs video
USB-C ports can have different functions. ASUS says plug-and-play display use requires video-function support at the computer port as well as the monitor.
Check the laptop’s specifications for DisplayPort Alt Mode or USB-C display output, then compare them with the exact monitor’s requirements.
-
Choosing by diagonal size alone
A larger screen needs more physical room. Lenovo UK lists stand adjustment on the 14-inch ThinkVision M14d, while LG UK’s +view 16MR70 has a larger 16-inch panel.
Measure the space beside the laptop and compare stand positioning alongside resolution and aspect ratio.
-
Expecting every portable monitor to power itself
LG says the +view 16MR70 has no built-in battery and sets specific requirements for power from the connected laptop.
Check how your chosen model is powered and whether laptop charging through the monitor needs a compatible charger.
For the LG +view 16MR70, a compatible USB-C charger may be an additional item for the intended charging setup.
-
Relying on a return instead of checking the setup
Returning an unsuitable online purchase and seeking a remedy for a faulty item are different matters. Neither replaces a compatibility check before ordering.
Test the monitor promptly with your intended laptop, cable and desk position, and keep the order details in case you need to contact the seller.

Frequently asked questions
Will any USB-C laptop port run a portable monitor?
No. ASUS explains that USB-C ports have different functions and that a plug-and-play display connection needs video-function support at the computer port. Check your laptop’s documentation for USB-C display output or DisplayPort Alt Mode, alongside the exact monitor’s requirements.
Can a portable monitor use up my laptop battery?
Yes, if the monitor draws its power from the laptop. LG says its +view 16MR70 has no built-in battery and is powered by the connected laptop; check that model’s power requirements and charger options rather than assuming other monitors work the same way.
What if a portable monitor bought online is faulty or does not suit my setup?
A faulty monitor and a change-of-mind return are different cases. GOV.UK says online buyers can generally cancel within 14 days after receiving an item and then have another 14 days to return it, subject to applicable exceptions. If the monitor is faulty or misdescribed, ask the seller about statutory remedies rather than treating the cancellation period as your only route.
What should I do with a portable monitor at the end of its life?
Use an appropriate electrical-equipment collection or recycling route rather than general waste. GOV.UK explains that UK waste electrical and electronic equipment measures encourage recovery, reuse and recycling; check the available retailer or local-authority arrangements.
