Choose an external monitor if your main problem is too little screen space; add a dock or adapter only when your laptop and display need a compatible connection or extra ports. Check your laptop’s supported video output, display limit and charging requirements before buying, then consider a stand or arm only if your desk setup needs different screen positioning.
If you regularly work across documents, spreadsheets or several applications, an external screen can give you another workspace without replacing your laptop. Check the display’s resolution and size alongside the video output your computer supports. Microsoft Support explains how resolution and scaling affect Windows display layouts.
If you return to one desk and want to connect a display and peripherals, check your laptop’s video-capable port, supported display count and charging needs before choosing a dock. Apple Support, Microsoft Support and Anker Support document different device and host requirements.
If you spend extended periods at a desk, consider whether the supplied stand puts the screen in a suitable position before adding a separate mount. The Health and Safety Executive’s posture guidance covers screen position and distance; mount fit and desk attachment still depend on the specific products.
Choose it when: your laptop screen feels cramped for documents, spreadsheets or meeting windows.
Trade-off: a separate screen uses desk space and needs a video connection supported by your laptop.
Choose it when: your laptop and display need a compatible connection, or you also need ports for peripherals.
Trade-off: a dock does not add screen space or automatically increase your laptop’s display limit.
Choose it when: your existing monitor works for you but its position or base makes the desk arrangement awkward.
Trade-off: an arm changes positioning, not display resolution or laptop compatibility, and must fit both the monitor and desk.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Readable documents and screen space | Check the monitor’s native resolution and physical size, plus your laptop’s supported video output. On Windows, Microsoft Support advises adjusting Scale separately; using less than native resolution can make text less sharp. | If I need several documents or windows visible, I want a screen that suits the work without taking over my desk. Around 28% of consumers put useful screen space first. |
| Compatible display connections | Confirm your exact laptop model’s video-capable port and supported display count. A USB-C connector alone does not confirm video capability or support for the display arrangement you want. | If I am adding a display or using more than one, I need the connection to work with my particular laptop. Around 22% of consumers prioritise display compatibility. |
| Screen position and desk fit | Check the supplied stand’s adjustment. For an arm, compare the monitor’s mounting pattern and weight with the arm’s limits, and check the desk attachment requirements. | If I work at the desk for long sessions, I want the screen positioned comfortably without crowding the available space. Around 22% of consumers put screen positioning first; the Health and Safety Executive’s posture guidance also discusses screen height and distance. |
| Charging and cables | Compare the laptop’s charging needs with the monitor or dock’s host-facing Power Delivery output. Check which cables and any separate power supply are included. | If I connect my laptop at the same desk each day, I want a convenient setup that also meets its charging requirements. Around 17% of consumers prioritise this kind of docking convenience. |
| Meeting facilities | Check the exact monitor’s listed audio facilities, and decide whether you will continue using your laptop’s camera, microphone and speakers. | If meetings are part of my desk routine, I want the facilities I actually use to remain available in the new arrangement. Around 11% of consumers put meeting facilities first. |
A connector that fits does not establish that the laptop supports the display output or configuration you need. The Anker 565, for example, requires host support for DP Alt Mode for its display outputs.
Check the full laptop model’s specifications and the dock or adapter’s host requirements before choosing the connection.
An unsuitable connection may leave you needing a different adapter or docking arrangement.
A dock’s advertised pass-through charging depends on its host requirements and power supply. Anker Support specifies a separately supplied 100W PD charger and cable for optimal 85W pass-through charging with the 565.
Compare the host-facing output with your laptop’s requirements, then check the package contents and any required separate power supply.
The required charger and cable may need to be purchased separately.
A larger screen will not by itself resolve an awkward viewing position. Mounting pattern, supported weight and desk attachment limits vary by model.
Check the supplied stand first. If you need an arm, verify the monitor and desk against that arm’s documented limits.
A compatible arm, riser or replacement stand may be needed for the arrangement you want.
Package contents can differ between monitors. LG states that the USB-C cable for the 27U631A-B is sold separately.
Check the exact model’s package contents and choose a cable that supports the display connection and charging arrangement you require.
The required cable may be an additional purchase.

The listing advises using a desk with sufficient depth and load capacity and having two people move and unbox the panel.
No. Check your exact laptop’s documented video output and the connection device’s host requirements. Anker Support, for example, specifies DP Alt Mode for the Anker 565’s display outputs and Power Delivery for charging.
Some configurations support two external displays, but the exact MacBook model and setup matter. Apple Support says its base-M3 MacBook Air and Pro arrangement requires the lid to be closed, external input devices and power; it also specifies macOS Sonoma 14.3 or later for Air and 14.6 or later for Pro.
In Windows, keep the screen at its recommended resolution and adjust Scale separately. Microsoft Support warns that using a resolution below the monitor’s native resolution can make text less sharp.
No. Match the monitor’s mounting pattern and weight to the arm, then check the desk attachment requirements. For example, the StarTech.com H1M1AG2-MONITOR-ARM specifies VESA 75 × 75mm and 100 × 100mm, a maximum weight of 10kg and a desk clamp range of 2–6cm.
Check the exact package contents and power requirements. LG states that the USB-C cable for the 27U631A-B is sold separately; Anker specifies a separate 100W PD charger and cable for optimal 85W pass-through charging with the 565.
