Travellers with few available sockets
If you compare flights, accommodation and booking terms on a laptop in a hotel, rental or shared room, a second screen is useful only if its connection and power needs fit the space.
Who needs an extra screen?
Laptop travellers seeking a one-cable setup
A portable display can extend or duplicate a laptop screen through one compatible USB-C connection. Check the laptop’s video-output capability before choosing this arrangement.
Travellers using HDMI devices
If another device needs HDMI, consider where the monitor will get power as well as how it will receive video. Joybuy’s Arzopa A1S instructions, for example, call for a separate USB power connection when using HDMI.
What matters when choosing?
Decide where you will compare bookings, then check your laptop’s display output and the monitor’s power requirements before weighing screen size against what you are willing to carry.
| Concern | What to check | Who this matters to |
|---|---|---|
| One-cable compatibility | Confirm that the exact laptop port outputs video over USB-C and that the monitor can receive video and power through its specified connection. | I have few free sockets and need the extra display to work directly with my laptop, rather than discovering that its USB-C port only charges devices. Roughly 42% of consumers put connection and socket certainty first. |
| Travel and temporary setup | Compare the exact model’s weight and packed size, then check its stand or cover for the table you expect to use. | If the screen is coming in my laptop bag, I need to carry it comfortably and set it upright on a temporary table. For roughly 33% of consumers, travel practicality is the primary concern. |
| Space for comparing pages | Choose between a compact portable screen, a larger portable screen and a fixed desk monitor; compare panel size, native resolution and where you will use it. | I want room to keep booking details visible together, but portability matters less if most comparisons happen at home. Around 25% of consumers prioritise viewing workspace when choosing. |
Buying pitfalls
-
Assuming every USB-C port carries video
A USB-C charging port alone does not establish that a laptop can drive a portable display. ASUS says USB-C plug-and-play requires video capability on both devices; Lenovo specifies DP1.2 Alt Mode and PD2.0 for its ThinkVision M14.
Check the exact laptop port specification against the requirements of the monitor you intend to buy.
-
Counting HDMI as a one-cable setup
HDMI provides the display connection, but the monitor may need power from another connection. Joybuy’s Arzopa A1S instructions require a USB-A-to-USB-C power cable for HDMI use.
Before choosing an HDMI setup, identify both the video cable and a suitable source of monitor power.
That arrangement may mean carrying an additional cable or USB power source.
-
Checking screen size but not the stand
A portable screen still needs a workable position beside the laptop, particularly on a small temporary table.
Check the exact model’s kickstand, cover-stand or mounting arrangement and whether it suits the surface you expect to use.
-
Treating the warranty as the only remedy for a fault
A manufacturer warranty does not replace statutory rights. Citizens Advice says a consumer with faulty goods may be entitled to a refund, repair or replacement, depending on the circumstances.
Keep your order confirmation and details of the fault, and contact the retailer about the available remedy rather than assuming you must deal only with the manufacturer.
Relevant brands to consider
ASUS
The ZenScreen line includes portable displays for laptop-based second-screen use.
- ASUS describes the ZenScreen MB16ACE as a 15.6-inch monitor weighing 0.71 kg, with an 8 mm profile and one USB connection for power and video.
- ASUS also says USB-C plug-and-play depends on video capability at both ends; the MB16ACE’s connection details should not be assumed to apply to every ZenScreen model.
Lenovo
The ThinkVision M14 is a portable display intended to extend or duplicate a compatible notebook screen.
- Lenovo specifies a one-plug connection for the M14 when the notebook’s USB-C port supports DP1.2 Alt Mode and PD2.0.
- Check those host requirements against your laptop; a USB-C connector by itself does not establish compatibility.
HP
HP describes one-cable setups for its Series 5 Pro 514pn and E14 G4 portable monitors.
- PCMag UK names the 514pn its overall favourite in its 2026 portable-monitor roundup; HP describes the model as a 14-inch WQXGA portable monitor.
- That roundup preference is not a judgement about a particular laptop or a room with limited sockets. Check the chosen model’s connection and physical setup.
MSI
The Pro MP165 E6 appears in PCMag UK’s 2026 portable-monitor roundup as its low-cost recommendation.
- The roundup provides a starting point for considering the Pro MP165 E6 alongside other portable models.
- Check the exact model’s power inputs and your laptop’s display output before relying on it for a one-cable setup.
Joybuy monitors for holiday planning
These monitors offer ways to add a screen while comparing holiday bookings on a laptop. Check each model’s video connection, power arrangement and space requirements before choosing one for a stay with limited sockets.

Common questions
Will any USB-C laptop work with a one-cable portable monitor?
No. The laptop port must support the video output required by the monitor, not just charging. ASUS says USB-C plug-and-play requires video capability on both devices, while Lenovo specifies DP1.2 Alt Mode and PD2.0 for its ThinkVision M14; check the requirements for your exact pairing.
Can HDMI work without using another wall socket?
It may, if you have a suitable source of USB power for the monitor, but HDMI alone does not settle the power question. Joybuy’s Arzopa A1S instructions call for a separate USB-A-to-USB-C power connection when using HDMI; check the instructions and available power outputs for the model you choose.
What should I do if a monitor arrives faulty?
Contact the retailer and describe the fault, keeping your order confirmation and any useful evidence. Citizens Advice says you may be entitled to a refund, repair or replacement depending on the circumstances; a manufacturer warranty does not replace statutory rights.
How should I dispose of an old monitor?
Check your local council’s arrangements for recycling electrical equipment or an available retailer take-back route. Oxfordshire County Council, for example, says its waste recycling centres accept household electrical items; arrangements at other sites should be checked locally.
