Check whether your laptop can send video to the portable monitor and meet its power requirements, then measure the space beside your laptop. A 14-inch screen is worth considering when desk width is tight; move to a 15.6- or 16-inch model if the extra screen area justifies its wider footprint. Resolution and colour specifications cannot make up for an incompatible connection or a stand that does not fit your setup.
If chat, documents or reference windows compete for space on your laptop, look for a screen and stand that fit beside it without crowding your keyboard or mouse. A single-cable arrangement is an option only if your laptop supports the required connection.
If you want a tidy USB-C connection, check both video output and power requirements before choosing a monitor. The shape of a USB-C port does not establish what it can do, as ASUS explains in its portable-monitor connection guidance.
If you work with dense documents, layouts or colour-sensitive material, compare resolution, aspect ratio and stated colour coverage after confirming that the display fits your desk and connects to your laptop.
For a second laptop screen on a small desk, settle the connection and physical fit before deciding how much display area or detail you need.
| Concern | What to check | Who this matters to |
|---|---|---|
| Laptop video and power compatibility | Confirm video output from the intended laptop port, the monitor input and the power arrangement. Check charging pass-through separately if you need it. | If my laptop cannot send video through the connection I plan to use, the screen will not extend my desktop. Around 40% of consumers would put connection and power compatibility first. |
| Desk footprint and positioning | Measure the space beside the laptop, allowing for the stand and cable exit; check how the screen can be tilted or supported. | I need the second screen to stay upright without displacing my keyboard or mouse. A workable footprint would be the primary concern for around 30% of consumers. |
| Workspace and image characteristics | Compare resolution, aspect ratio and screen finish; for colour-focused work, check what the stated gamut specification covers. | Once the screen fits and connects, I want enough room for documents or the image characteristics my work calls for. Around 30% of consumers would make that their main priority. |
USB-C describes the connector, not a guaranteed display function. A direct USB-C monitor connection requires a compatible video path; ASUS also documents DisplayLink arrangements that use a driver on certain models.
Check the exact laptop and monitor specifications before choosing a USB-C-only model. If you need another connection method, confirm its video, power and any driver requirements as a complete setup.
A 15.6- or 16-inch display offers more physical screen area than a 14-inch model, but also takes more space beside the laptop.
Measure the available width and account for the stand, laptop, keyboard, mouse and cable exit. Where width is the limiting factor, compare compact models and their positioning options before moving up in size.
Power needs and charging pass-through differ by model. LG specifies both DisplayPort Alt Mode and USB Power Delivery output above 7.5 W for a device connected to its 16MR70.
Compare the exact monitor's power requirements with your laptop and charger before relying on one-cable charging.
The intended pass-through arrangement may require a suitably rated USB-C charger.
Colour coverage does not describe how a screen will fit your desk or handle reflections. ASUS lists its ZenScreen OLED MQ16AH with a glare surface and 1920 × 1080 resolution.
For document work, compare resolution, aspect ratio and surface finish. For colour-sensitive work, check whether the manufacturer's stated gamut specification meets your workflow needs.
Lenovo's ThinkVision range includes compact portable displays for extending a laptop screen.
HP's Series 5 Pro 514pn is a compact, higher-resolution portable-monitor option.
LG's 16MR70 represents a larger, 16:10 portable-display option.
ASUS ZenScreen models offer different portable-display connections and panel characteristics.
Dell's P1424H is a compact portable-monitor reference for desk fit and positioning.
These portable monitors offer 14-inch and larger-screen choices for a second laptop display. Compare each model's connection requirements and desk fit before choosing.

Consider this smaller screen where desk width is tight and touch input matters. The product name specifies 100% sRGB, VESA compatibility and a stand adjustable through 180°. Check its overall dimensions and whether your laptop can provide the video and power needed for your intended connection.
No image available
Consider this model if you need an FHD second screen and want to assess connection options beyond a USB-C-only setup. Measure the space available beside your laptop, and confirm video compatibility and the power arrangement for the connection you intend to use.
No image available
Consider this FHD model if its size and intended connection suit the space beside your laptop. Before buying, confirm the laptop's video output, the monitor's power requirements and how you will position the screen.

Consider the larger panel if you can spare the desk width and want a 16:10 layout. Its product name specifies 2560 × 1600 resolution, Mini HDMI, USB-C and VESA compatibility. Check the intended input's video and power requirements and how the monitor will be supported on your desk.
No: a USB-C connector does not guarantee video output. For a direct USB-C display connection, check that the laptop output and monitor input support a compatible video mode such as DisplayPort Alt Mode. ASUS also describes DisplayLink arrangements on certain models, which require a driver.
Select Extend in Windows display settings, or press the Windows logo key and P, then choose Extend, as Microsoft Support advises. If the second screen is not detected, check the cable and video-capable port before changing display settings again.
That depends on the monitor and connected device. LG says its 16MR70 has no built-in battery and can draw power from the connected laptop; for LG's stated simultaneous monitor-and-laptop charging arrangement, the charger must support 65 W input and 45 W output. Check the power specification of the exact model you choose.
GOV.UK says Great Britain continues to recognise CE marking alongside or in place of UKCA marking where the relevant product regulations meet UK needs. That guidance applies to England, Scotland and Wales; Northern Ireland follows different processes, so check the requirements applicable there separately.
