Start with your computer’s supported video output and the connection your monitor needs. A directly compatible external monitor suits a straightforward second-screen setup; consider a USB-C or Thunderbolt docking monitor, or a separate dock, when you also need charging or desk peripherals and have confirmed that the laptop supports the connection. For workers covered by display screen equipment requirements in Great Britain, an employer’s workstation assessment may need to cover both home and office arrangements.
Check the laptop’s supported external-display connection before choosing what stays on your home desk. In Great Britain, the Health and Safety Executive says an assessment should cover both home and office where a worker uses display screen equipment in both places.
Compare the monitor’s dimensions with your available space, then check its stand adjustments or specified mounting interface if you need to change its position. Screen size alone will not tell you how it fits the whole workstation.
A USB-C or Thunderbolt monitor or dock is worth considering if the laptop supports the required video connection. Check charging requirements and the peripheral ports you will use rather than relying on the connector name alone.
Choose the connection route first, then compare screen fit and desk functions; an adapter, docking monitor and monitor arm solve different parts of the setup.
Choose when: Your computer has a confirmed video output that can connect to the monitor, and a separate work screen is the main requirement.
Consider: Different ports may still require a compatible cable or adapter.
Choose when: Your laptop supports video over the required connection and you also want specified charging or peripheral functions at the desk.
Consider: A USB-C socket does not, by itself, establish video support or sufficient charging power.
Choose when: A suitable monitor needs a different connection from the laptop, or you need desk ports beyond those on the monitor.
Consider: Check the complete laptop-to-display path; an adapter or dock cannot create an unsupported display configuration.
| Priority | What to check | Your needs |
|---|---|---|
| Display connection | Check the exact computer model’s supported video outputs, the monitor input and the cable or adapter between them. Confirm the intended resolution and refresh rate for that complete connection. | I want the second screen to run in the display mode I plan to use, whether it connects directly or through an adapter. |
| Screen positioning | Check stand adjustments. If using an arm, confirm the monitor’s mounting pattern and weight against the arm’s specifications. | My screen needs to fit the position available on my desk; an arm is only an option if the monitor and mount are compatible. |
| Docking functions | Check laptop video support over USB-C or Thunderbolt, charging requirements, and the monitor’s or dock’s stated power delivery and peripheral ports. | I would like to connect desk accessories or charge my laptop through the setup, but only if the selected devices support those functions together. |
| Desk space | Compare the display’s dimensions with your desk. Consider screen size, aspect ratio and native resolution alongside the computer’s supported output mode. | A smaller screen may fit my limited desk space, while a larger format is worth considering if I have room for the way I work. |
| Workstation assessment | For work in Great Britain, check whether you use display screen equipment daily as part of normal work for continuous periods of an hour or more, and follow your employer’s assessment process. | If I work at home and in an office, I want both arrangements considered where the Health and Safety Executive’s display screen equipment assessment requirements apply. |
Microsoft Support says external-display capability depends on the computer model and the cables or adapters used. The connector’s shape is not enough to establish the display mode or charging path.
Check the laptop model, documented video output, monitor input and intended resolution and refresh rate before selecting a cable or dock.
A compatible cable or adapter may be a separate item; Apple says its USB-C Digital AV Multiport Adapter requires an HDMI cable sold separately.
In Great Britain, the Health and Safety Executive says employers must assess workstations for people who use display screen equipment daily as part of normal work for continuous periods of an hour or more. Where they use it at home and in the office, the assessment should cover both situations.
If that describes your work, check your employer’s assessment process before deciding which equipment to buy personally.
VESA defines display mounting interfaces, but that does not establish that a particular monitor has one or that an arm can carry it.
Check the exact monitor’s mounting pattern and weight, the arm’s supported range, and how the arm attaches to your desk.
These model references illustrate different connection and desk-setup features; a brand’s inclusion does not establish that every model has them.

The Lenovo ThinkVision P27u-20 illustrates a docking-monitor option for a desk with multiple connected devices.
These are external monitors to consider for a home or hybrid desk. Match each one to your computer’s video output and your available space; choose any adapter, dock or arm separately according to compatibility.

Consider this WQHD monitor for a fixed second-screen desk setup. Check its inputs against your computer’s output, and confirm stand adjustments and USB-C charging requirements for your intended arrangement.

This QHD monitor is an option when fitting a separate display into a desk setup. Confirm its dimensions, the video connection your laptop supports and the USB functions of the specific unit if peripherals are part of your plan.

The 24-inch format is worth checking where desk space shapes the choice. Confirm the exact unit’s refresh rate and connections before selecting a cable or relying on USB-C functions.

This 31.5-inch 4K monitor is an option if its dimensions suit a fixed desk. Check your laptop’s USB-C video support and the monitor’s charging capabilities before planning a one-cable connection.

No. Microsoft Support says external-display capability depends on the computer model and the cables or video adapters used. Check your laptop’s specified video output, then match it to the monitor input and the display mode you need.
Consider a separate dock when an otherwise suitable monitor does not provide the connections you need at the desk. Confirm the dock, laptop and monitor work together for the intended video output, charging and peripherals; a dock does not make an unsupported display configuration available.
No. VESA defines mounting interfaces, but the monitor’s own specification must confirm its mounting pattern. Check that pattern and the monitor’s weight against the arm’s supported range, as well as the arm’s desk attachment.
