Choose the connection and power arrangement before the screen size: a one-cable USB-C setup needs a laptop port that sends video and can supply the monitor with power. For work away from a socket, compare the monitor’s stated power consumption, carry weight and stand; a USB-A or HDMI fallback may instead require a driver or a separate power connection.
If you work on trains, at client sites or in shared spaces, you need a second screen whose power arrangement suits your laptop when no socket is available. Check the monitor’s stated consumption and carry weight alongside its video connection.
An older or managed laptop may have USB-C without video output. Confirm the exact port’s capabilities before choosing native USB-C video, a driver-dependent USB-A connection or HDMI with a suitable power source.
If you need room for documents, spreadsheets, code or presentations, consider the screen’s shape, resolution and stand adjustment. Check the conditions for portrait rotation rather than assuming it works automatically on your laptop.
Establish how the monitor will receive video and power away from a socket, then weigh compatibility fallbacks, portability and task-specific screen features.
| Concern | What to check | Who this matters to |
|---|---|---|
| One-cable use away from mains power | Confirm video output on the laptop’s exact USB-C port, the monitor’s video input and how it receives power. | I want to open a second screen where there is no socket, without discovering that my USB-C port carries only data or charging. Around 33% of consumers put reliable one-cable, off-mains use first. |
| Connection fallback | Check whether USB-A needs a driver, or whether an HDMI connection also needs separate monitor power. | With an older or managed laptop, I need a connection I can actually use under its software restrictions. For around 25% of consumers, that fallback is the primary concern. |
| Travel positioning | Compare stated weight and stand adjustment; check any software or operating-system conditions for portrait rotation. | A screen has to fit in my bag and stand comfortably on a temporary desk before extra features matter. Carrying and positioning it come first for around 25% of consumers. |
| Display and task features | Compare resolution and aspect ratio for your work; check touch compatibility if you need direct screen input. | For documents, presentations or annotation, I need the screen layout or touch function to suit the task. Around 17% of consumers prioritise those capabilities. |
A port used for data or charging may not extend the laptop display, even when the cable fits. ASUS support advises checking that the computer’s USB-C port has a video function.
Confirm video output or DisplayPort Alt Mode for the exact laptop port, then compare it with the monitor’s input requirement.
A feature that charges the laptop through the monitor can depend on an external adaptor. ViewSonic specifies one for the VA1655’s USB-C charging function.
For use away from mains power, establish what powers the monitor itself and compare its stated consumption with your laptop’s battery capacity.
The ASUS ZenScreen MB16ACE’s hybrid USB-A connection requires a DisplayLink driver, which may be difficult to install on a managed work laptop.
Check installation permissions before relying on USB-A. If installation is blocked, assess a confirmed native USB-C video connection or an HDMI route with suitable monitor power.
On a managed device, obtaining installation permission may take time or require IT assistance.
Automatic rotation can depend on software and the operating system, rather than the screen alone.
For the ASUS ZenScreen MB16ACE, check whether its Windows-only DisplayWidget rotation feature fits the laptop you intend to use.
The 14-inch M14 and M14d are compact portable-monitor options for extending a laptop desktop.
The MB16ACE offers a hybrid connection option for laptops that may lack native USB-C video.
The VA1655 offers a standard portable screen, while the TD1655 adds touch for workflows that use direct input.
The I1601FWUX is a 15.6-inch Full HD IPS option built around a USB-C connection.
The P1425 is a 14-inch, 16:10 portable display with an adjustable tilt stand.
These portable monitors are options for extending a laptop screen while travelling. Check each model’s connection and power arrangement against your laptop before relying on it away from a socket.

For a USB-C laptop-extension setup, confirm that the laptop port sends video and can meet the monitor’s power requirements away from a socket.

This is an option for a laptop-extension setup using USB-C video; confirm DisplayPort Alt Mode on the exact laptop port and assess the monitor’s draw against your battery needs.

Consider touch if direct screen input matters to your work; check touch compatibility, laptop video output and the power arrangement for use away from mains.
14-inch, 60 Hz touchscreen with an adjustable 180° stand and VESA mounting. The product name states 100% sRGB as a manufacturer specification.
No. The laptop’s port must support video output, commonly DisplayPort Alt Mode, and the monitor must accept that connection. ASUS support recommends checking the video function of the computer’s USB-C port; a USB-A alternative may require its specified driver.
Compare the monitor’s stated typical consumption with your laptop battery capacity and usual workload, but do not treat that figure as a runtime prediction. ViewSonic specifies 7 W typical for the VA1655 and 8 W for the touch-enabled TD1655; screen settings and other connected devices also affect laptop runtime.
HDMI can provide a video route if both devices have compatible connections, but the monitor still needs power. The ViewSonic VA1655 has mini HDMI as well as USB-C power input, so establish its power source before choosing it for use away from a socket.
No. Pass-through can describe an arrangement that uses an external adaptor to power the monitor and charge the laptop. Check the model’s power specification separately if you need the monitor to operate without mains power.
