A separate monitor is not essential for every home-working laptop setup: the Health and Safety Executive advises either raising the laptop screen while using a separate keyboard and mouse, or using a separate display. If one screen is enough, a riser may answer the positioning problem; consider a fixed monitor for a regular desk and a portable second screen when you move between workspaces. Before buying a display, check its video connection against your exact laptop and how you will position the screen.
If you use a laptop for prolonged work at the same desk, consider whether its screen can be positioned comfortably without leaving the attached keyboard and trackpad awkward to use. The Health and Safety Executive advises a separate keyboard and mouse when raising a laptop screen, or a separate display.
If your workspace changes, a portable second display may be useful when you need more screen space away from your main desk. Check what you are willing to carry and whether each laptop you use can provide the display’s required video connection.
When a fixed monitor, laptop and input devices must share a small surface, compare the space each arrangement needs. An arm or stand is worth considering only after checking the exact display’s mounting and positioning options.
Start with whether you need another screen at all, then check where you will use it and how it connects to your laptop.
Consider it when: One laptop screen is sufficient, but you need to raise it for prolonged work, as described in Health and Safety Executive guidance.
Trade-off: A riser does not add screen space, and the raised laptop still needs a separate keyboard and mouse for this arrangement.
Consider it when: You work mainly at one desk and want another screen that can be positioned independently of the laptop.
Trade-off: It takes permanent desk space; its inputs, adjustment and any laptop-charging capability depend on the exact model.
Consider it when: You need extra screen space at several work locations and want to pack the display away.
Trade-off: Check both its video requirements and its positioning options; for example, ASUS specifies USB-C DisplayPort Alt Mode but no height adjustment for the ZenScreen MB166C.
| Priority | What to check | Your needs |
|---|---|---|
| Screen and input position | Check where the screen will sit and whether the keyboard and mouse remain usable. The Health and Safety Executive advises raising a laptop screen with a separate keyboard and mouse, or using a separate display for prolonged laptop work. | I use my laptop for long stretches and want to position the screen without having to type on a raised keyboard. |
| Screen space and portability | Decide whether one screen is sufficient and whether a second one will stay at a desk or travel with you. For a portable model, check its carrying size, weight and means of support. | I need documents or applications visible beside my laptop work, but my setup may have to move between locations. |
| Video connection | Match the laptop’s documented video output to the display’s input and the cable you plan to use. For a USB-C display requiring DisplayPort Alt Mode, confirm that the laptop’s USB-C port supports video; the connector shape alone is not enough, as the Video Electronics Standards Association’s USB-C guidance makes clear. | A second screen is useful to me only if it can receive video from the laptop I actually use. |
| Desk position and mounting | Check the supplied stand’s adjustments. If adding an arm, match its mounting pattern to the exact monitor’s documented interface; the Video Electronics Standards Association defines the mounting-interface standard, but the pattern must still match. | Desk surface is limited, so I want to know where the display and its stand or arm will fit before committing to a fixed setup. |
A USB-C portable display requiring DisplayPort Alt Mode needs a compatible video output, not merely a USB-C-shaped laptop port. ASUS specifies this mode for the ZenScreen MB166C.
Compare your exact laptop port specification with the display’s input requirement before ordering, and check the cable requirement too.
Lifting the screen also lifts the keyboard and trackpad, so the screen and input devices can no longer be positioned separately.
For prolonged laptop work, use a separate keyboard and mouse with a riser, as the Health and Safety Executive advises.
A portable screen’s positioning depends on its exact design. ASUS lists no height adjustment for the ZenScreen MB166C, so its portability does not establish that it will sit at the height needed at a permanent desk.
Check how the display will be supported and positioned in each workspace, especially if it will spend most days at one desk.
Screen size does not identify a monitor’s mounting interface. Dell specifies a 100 × 100 mm VESA interface for the U2421E, but that specification cannot be assumed for another model.
Find the exact monitor’s documented mounting pattern and match it to the arm or stand before buying.
ASUS’s ZenScreen MB166C is an example to examine if you want a portable second screen for laptop work.
Dell’s U2421E illustrates features to compare when planning a fixed monitor at a home desk, rather than a current purchase recommendation for that model.
Lenovo describes USB-C connectivity within its ThinkVision monitor range for desk setups involving multiple devices.
These Joybuy options include fixed monitors for a regular desk and a portable second display for work across locations. A riser with separate input devices remains an alternative when one laptop screen is enough.

Consider this fixed monitor if you want a separate screen at your usual desk. Check its stand position and confirm which video connection your laptop can use before relying on a USB-C setup.

This fixed-screen option is relevant if your laptop workstation stays at one desk. If you want video and charging through USB-C, check the exact laptop’s DisplayPort Alt Mode and power-delivery compatibility first.

Consider this fixed monitor when you need a separate screen at a regular workstation. Check its positioning options and match your laptop’s video output to the connection you intend to use; USB-C charging also requires a compatible laptop.

This is another fixed-screen option for a home desk. Before choosing a connection, confirm the exact port configuration for the P2425; its USB-C and VGA details conflict across the product information. Check the refresh rate too if it matters to your choice.

Consider this portable display if you need a second screen at more than one work location. Confirm that your laptop can output video through USB-C DisplayPort Alt Mode, and check how you will position the display wherever you use it.
Not necessarily. The Health and Safety Executive describes raising the laptop screen with a separate keyboard and mouse, or using a separate display, for prolonged laptop work. A monitor is worth considering if you also need more screen space or a screen positioned independently at your desk.
No. A display requiring video over USB-C needs a compatible laptop video mode, such as DisplayPort Alt Mode. Check the exact laptop port, display input and cable requirements; ASUS specifies DisplayPort Alt Mode for the ZenScreen MB166C.
No. Check whether the exact monitor has a mounting interface and match its documented pattern to the arm. The Video Electronics Standards Association documents the mounting-interface standard, while Dell specifies a 100 × 100 mm VESA interface for the U2421E specifically.
The Health and Safety Executive advises placing the top of the screen around eye level, about an arm’s length away, with the screen directly in front of you. Check that the arrangement also leaves the keyboard and mouse at a usable position rather than raising the attached laptop keyboard with the screen.
Yes, in the circumstances described by the Health and Safety Executive: the regulations can apply to people working at home permanently or long term, or routinely splitting work between home and a workplace. HSE says employers must assess workstations when workers use display screen equipment daily as part of normal work for continuous periods of an hour or more; that duty does not prescribe a particular monitor for every worker.
