For a mobile second screen, choose a USB-C monitor if your laptop supports DisplayPort Alt Mode video and can meet the monitor’s power requirements. If USB-C video is uncertain, an HDMI-capable model gives you another connection route, but you must still plan how to power it. Touch and dual-screen designs make more sense when your work calls for them often enough to justify their compatibility checks and extra kit.
If you move between home, client sites and temporary desks, a USB-C screen may keep the connection simple. Check your laptop’s exact port specification for DisplayPort Alt Mode and confirm how the monitor receives power.
If you sometimes connect client equipment or an older laptop, a monitor with HDMI or mini-HDMI offers another video route. Check the required cable and power supply before packing.
Touch may be useful for regular annotation or visual navigation; a foldable dual-screen model offers another panel for recurring multi-window work. Check operating-system support for touch and whether the larger setup fits your usual bag and desk.
Start with the laptop connection and monitor power arrangement, then compare what you will need to carry and set up at each workspace.
| Priority | What to check | Your needs |
|---|---|---|
| Video connection | Check the laptop’s exact USB-C video specification and the monitor’s required input. DisplayPort says video over USB-C uses Alternate Mode; a USB-C connector alone does not establish video support. If using HDMI, check the socket and cable sizes at both ends. | I want to connect a second screen at different desks without discovering that my work laptop cannot send it a picture. |
| Power and cables | Confirm the monitor’s power input, whether the host can supply it, and what charger or cables are needed. Check any power pass-through arrangement against the specific monitor, laptop and charger. | On a train or at a client site, I need to know what must be plugged in before I can use the screen. |
| Viewing position | Compare stand adjustment, brightness controls and screen reflections in the places you expect to work. A case that doubles as a stand may position the screen differently from an adjustable hinged stand. | A shallow table or changing indoor light makes screen angle and readable settings important to me. |
| Carrying and specialist features | Compare the exact model’s weight and packed accessories. For touch, check host and operating-system support; for dual screens, check the required connections and space for both panels. | I carry my setup regularly, so an extra panel or touch controls need to earn their place in my bag through work I actually do. |
A USB-C connection may provide data or power without the native video output a portable monitor needs. USB graphics alternatives can also require a driver.
Check the laptop’s exact model documentation for DisplayPort Alt Mode or another supported external-display connection. If that remains uncertain, consider a monitor with an HDMI input and check its power needs separately.
HDMI provides a video route, but the monitor may still need power through another cable or adaptor.
Before travelling, confirm the monitor’s power input, required supply and included equipment for the connection you intend to use.
A separate charger or power cable can add to what you need to carry.
A screen that is awkward to position or affected by reflections can be difficult to use at a temporary desk; a larger setup also changes what you carry.
Compare the exact model’s weight, brightness controls, screen surface and stand adjustment alongside its display size.
Touch behaviour depends on the host and operating system. A dual-screen unit also needs space and adds carry weight: ASUS lists its ZenScreen Duo MB14FCD at 1.2 kg.
Choose these features around recurring annotation or multi-window work, and check the intended device’s touch or multi-screen connection requirements.
Lenovo’s UK ThinkVision portable range includes compact USB-C work screens and a touch-enabled option.
ASUS lists portable models with different connection and panel arrangements, so the model number matters.
ViewSonic’s UK portable displays include USB-C and mini-HDMI work screens alongside touch models.
Acer describes the PD3 series as a foldable dual- or triple-screen portable-monitor range.
These options cover compact USB-C screens, models with HDMI connections, a touch display and larger screens for temporary workspaces. Compare each one with the laptop, power supply and carrying setup you intend to use.

A portable second-screen option for a laptop-based travel setup. Check that your laptop can output video through the connection you plan to use, and confirm the stand and power arrangement for temporary desks.

Consider this USB-C model for a temporary workspace where positioning matters. Before choosing it for frequent travel, confirm the shipped model’s weight: the product information gives conflicting figures of 2.8 kg and 4.84 kg. Check the included power adaptor and whether your laptop supports the intended video connection.

The stated 18.4-inch, 3840 × 2160 display offers a larger second-screen format for a temporary desk. Its product name lists USB-C, Mini HDMI, an integrated mount and VESA compatibility. Check the weight, supplied support, host video connection and power requirements before treating it as a frequent-carry screen.

This touch option is worth considering for regular annotation or visual navigation. The product name specifies a 180° adjustable stand and VESA compatibility. Check touch support for your exact device and operating system, along with video output, power needs and carry weight.

For a second screen at a temporary desk, the product name specifies 2560 × 1600 resolution, Mini HDMI, Type-C and VESA compatibility. Check the host’s video output, the monitor’s power needs and which stand or cables you would carry; also confirm the weight if it will travel daily.
Check the exact laptop model’s specifications or manufacturer guidance for DisplayPort Alt Mode or another supported USB-C video output. A USB-C socket by itself does not confirm video capability; a USB graphics connection such as DisplayLink may instead need a driver.
It gives you a video route when your laptop’s USB-C video output is absent or uncertain, or when you need to connect HDMI equipment at another workspace. Match the cable to both sockets and plan monitor power separately.
That depends on the monitor, laptop and connection. Check whether the host can supply the monitor’s required power and whether any power pass-through needs a compatible charger; ViewSonic says the VA1655’s power-charging feature requires an external power adaptor.
Check that you can position the screen securely, adjust its brightness and manage reflections in the available light. Compare the stand or case-stand with the table space you typically have, then include its cables and support in your carrying plan.
No. Check the exact monitor’s touch connection and operating-system requirements before buying it for annotation or navigation. For example, ViewSonic says TD1655 touch feedback does not apply to iOS or iPadOS devices.
