Choose a fixed, adjustable monitor if your laptop usually stays at one desk; choose a portable monitor if the extra screen needs to travel with you. A dock can reduce repeated cable changes, but before buying any of these, check your laptop’s video output, supported number of external displays, cables and charging requirements. Microsoft notes that a basic splitter duplicates a signal rather than creating an independent extended display.
Where you use the laptop most often is the starting point: screen size and positioning matter differently at a permanent desk and on the move.
If documents, meetings and work applications share one regular workstation, consider a separate screen that you can position alongside a keyboard and mouse. The UK Health and Safety Executive advises using separate input devices and elevating the screen for prolonged laptop use.
A portable display can provide an extra screen at different desks, but its connection method needs checking before it goes in your bag. Depending on the model, USB-C video capability or installed DisplayLink software may be required, as ASUS explains in its portable-monitor guidance.
A compatible hub monitor or dock may connect a display and peripherals with fewer repeated cable changes. Check the laptop’s video-capable ports, external-display limit and charging requirements before relying on a one-cable arrangement.
Consider it when: Your laptop usually stays at one workstation and you want a separate display for documents, meetings and other work tools.
Trade-off: It occupies desk space and is less convenient to take between locations; USB-C charging also depends on the exact laptop and monitor.
Consider it when: The second screen needs to move with your laptop between workspaces.
Trade-off: The portable models described by Lenovo and ASUS have smaller displays than the fixed desk example described by Dell, and their connection requirements vary by model.
| Priority | What to check | Your needs |
|---|---|---|
| Display compatibility | Check the exact laptop model’s video ports and supported number of external displays. Match the monitor connection and cable to a video-capable output; for USB-C, confirm video support rather than judging by the socket shape. | I want an extended desktop, not a screen that merely duplicates my laptop. Apple advises Mac users to check ports, display support and cables; Microsoft says a splitter duplicates one signal rather than creating independent extended displays. |
| Desk positioning | Compare the exact monitor’s height, tilt and pivot adjustments with your desk arrangement. For prolonged laptop work, plan where a separate keyboard and mouse will sit. | When I work at one desk for extended periods, I want to position the display without raising the laptop keyboard with it. That follows the Health and Safety Executive’s guidance on prolonged laptop use. |
| Portability | Compare the screen dimensions, stated weight and carrying arrangement of the exact model. Check whether its video connection needs USB-C DisplayPort Alt Mode or a driver-based alternative. | My second screen needs to move between desks, so carrying it and connecting it at each location matter more to me than keeping a larger display in one place. |
| Charging | If you want one USB-C connection for video and charging, compare the monitor or dock’s stated power delivery with the laptop maker’s charging specification. Confirm that both devices support the intended USB-C functions. | I would like fewer cables at my desk, but I need to know whether the display connection can also meet my laptop’s charging requirements. |
| Dock or adapter | Match the dock or adapter to the laptop’s port, operating system and intended display arrangement. Confirm the laptop’s external-display limit before choosing a multi-monitor connection. | My monitor and laptop have different connectors, or I reconnect desk peripherals often. I need the dock to fit a display arrangement my laptop actually supports. |
USB-C connections can provide different combinations of functions. ASUS explains that plug-and-play video on a portable monitor requires video capability on the relevant USB-C connection, while DisplayLink-based connections require a driver.
Check the laptop’s exact port specification and the monitor manual for the required video method, software and power connection.
Microsoft states that a splitter duplicates a signal rather than creating two independent extended displays. A dock also needs to work within the laptop’s supported display configuration.
Confirm the laptop model’s external-display limit, then check the intended dock and monitor connections together.
A portable screen is useful when it moves with the laptop. At a regular workstation, display size and adjustment may deserve more attention; the Health and Safety Executive also advises elevating the screen and using separate input devices for prolonged laptop work.
If the display will remain at one desk, compare fixed monitors’ dimensions and stand adjustments before prioritising a carrying-friendly design.
A monitor’s stated power-delivery figure does not establish whether it meets a particular laptop’s charging requirement. Dell, for example, states up to 90 W for the P2425E, but suitability still depends on the laptop.
Compare the exact monitor or dock specification with the laptop maker’s charging specification before planning to leave the laptop charger disconnected.
These model-specific examples show why a brand name alone cannot settle the choice: compare the exact display and your laptop’s connection requirements.
Dell’s UK P2425E is a fixed-desk USB-C hub monitor with a 24-inch 16:10 display.
Lenovo UK describes the ThinkVision M14t Gen 2 as a 14-inch portable display with two USB-C ports.
ASUS’s UK ZenScreen MB16ACE is a 15.6-inch portable monitor with native USB-C and a hybrid-signal USB Type-A connection option.
These options include desk monitors and movable second screens for laptop workspaces. Compare each model’s connections with your laptop before deciding whether it fits your setup.

Consider this for a fixed laptop workstation where screen positioning and connections matter. The product listing describes an adjustable stand and USB-C power delivery of up to 96 W; confirm that your laptop sends video over USB-C and that this power level meets its charging requirement. Check which cable is included for the version you buy.
No image available
This is a fixed-desk option to consider if you want to position a separate screen alongside your laptop. Its listing describes an adjustable stand and HDMI, DisplayPort and USB-C connections. Match the chosen connection to your laptop, and confirm the USB-C power-delivery figure before relying on one cable for charging.

The listing describes positioning accessories for using this screen in different workspaces, plus USB-C and HDMI connection options. Its stated weight conflicts between 2.8 kg and 4.84 kg, so confirm the weight before choosing it for frequent travel. Also check laptop USB-C video support and whether the listed 60 W power delivery meets your charging needs.

For work across locations, this portable model is listed with a 15.6-inch display and a stated weight of 780 g. Its described USB-C video connection uses DisplayPort Alternate Mode, so check that the intended laptop port supports it. Confirm the laptop’s external-display support as well.

This fixed-desk monitor is listed with an adjustable stand and HDMI and DisplayPort connections. The product information conflicts on refresh rate and on whether USB-C video input is present. Check the exact model’s ports and refresh-rate specification before choosing a cable or planning a USB-C setup.
Check the exact model’s video ports, supported number of external displays and suitable cables or adapters; also check its charging requirement if you want power through the display connection. Apple gives those display and cable checks for Macs, while Microsoft advises checking the computer’s graphics capability for a multi-monitor Windows setup.
No. Confirm that the laptop’s port and the monitor support video over the intended USB-C connection, and check the cable requirements. ASUS explains that plug-and-play portable-monitor video needs USB-C video functionality; a DisplayLink-based alternative requires a driver.
No: Microsoft states that a splitter duplicates the same signal rather than creating two independent extended displays. For an extended desktop, check the laptop’s supported display count and choose a compatible display connection or dock.
No. For prolonged laptop use, the Health and Safety Executive advises a separate keyboard and mouse so the screen can be elevated, with a separate display also an option. Plan the screen and input-device positions together rather than treating the monitor as the whole workstation setup.
