Start with the computer you already use: check its video output and supported number of external displays, then choose a monitor input and cable that match. For regular desk work, make sure the screen can be positioned comfortably; a USB-C charging monitor is worth considering only if your computer supports video through that connection and the monitor supplies enough power for it.
If you want documents, calls and other windows visible beside your laptop, establish the laptop’s external-display support and the connection you will use before choosing a monitor. Microsoft Support and Apple Support both provide model- or system-specific guidance for connecting external displays.
If you spend long stretches at one desk, consider how the monitor, keyboard and mouse will fit together. The Health and Safety Executive advises positioning a screen with its top around eye level and at roughly arm’s length.
A USB-C docking monitor may combine a display connection and laptop charging, but check the exact computer’s video capability and charging requirements. The connector’s shape alone does not establish what it can do.
For a monitor used with an existing computer, establish a working display connection first. Then decide how much screen space and stand adjustment your desk needs, and whether integrated charging would be useful.
| Concern | What to check | Who this matters to |
|---|---|---|
| Connection compatibility | Match the computer’s video output to a monitor input or a documented compatible adaptor. Check the computer’s supported external-display count, particularly if you plan to use more than one external screen. | If I am adding a screen to my existing laptop, I need to know that the connection will carry video and support my planned display arrangement; around 31% of consumers would put connection compatibility first. |
| Screen position and desk fit | Check desk depth, stand footprint and height adjustment. If using an arm, check the monitor mount and the desk edge or clamp requirements. | When I work at the same desk for long periods, I need a screen position that fits my viewing distance and keyboard layout; roughly 25% of consumers would make desk fit and positioning their main concern. |
| Document workspace | Consider screen size, resolution and aspect ratio together with viewing distance. For documents and spreadsheets, decide whether extra vertical or side-by-side space would be useful. | If I regularly move between documents, email and calls, I want enough visible workspace without overwhelming my desk; around 25% of consumers would prioritise document and multitasking space. |
| Useful features without extras | Decide whether you need a display connection only or also laptop charging and connected peripherals. Confirm the functions of the particular USB-C port and any supplied cables. | If a direct cable already meets my needs, I may prefer a straightforward second-screen setup to docking functions I will not use; roughly 19% of consumers would put that simplicity first. |
The computer, monitor and cable all matter. Apple Support specifies display-mode requirements for relevant Mac adaptors, while a monitor’s charging capability depends on its particular model.
Check your computer model’s display and charging specifications against the monitor and cable before choosing a one-cable setup.
An incompatible cable, adaptor or dock may need replacing.
A port on the monitor does not establish which cables are in the box. You may have a suitable computer output and monitor input but still need a different cable or adaptor to connect them.
Compare the computer output, monitor input and stated box contents before ordering.
A larger panel still needs to fit at a workable height and viewing distance. The Health and Safety Executive’s display-screen guidance also considers the position of the keyboard and other equipment.
Measure the usable desk and check the stand’s adjustment range or an arm’s mounting requirements alongside screen size.
An arm, support, separate keyboard or mouse may be needed for the layout you want.
Supported external-display arrangements vary by computer model. Apple Support directs Mac users to their model’s Display Support or Video Support specifications.
Check the exact computer specifications before planning a multi-screen or closed-lid arrangement.
Dell’s Pro examples include conventional office monitors and USB-C hub monitors, giving buyers different ways to connect a laptop.
BenQ’s GW home-office range includes compact monitors for buyers who want stand adjustment without making a docking setup the centre of the purchase.
LG’s Ergo example is relevant when adjustable placement and a clamp-mounted stand are important to the desk layout.
Lenovo ThinkVision includes USB-C docking-monitor options for buyers considering display and laptop charging through one connection.
These monitors offer different screen sizes and desk arrangements for an existing home-working computer. Choose the display connection and physical fit that suit your setup; a USB-C connection or an adjustable stand should be assessed on the particular model.

For a desk-based second screen, this model offers stand adjustment alongside conventional video inputs. Dell specifies HDMI, DisplayPort and VGA, plus height, tilt, swivel and pivot adjustment for the P2425H. Check the supplied cable, and confirm the port functions before relying on USB-C for video or charging.

Consider the larger screen if you want room for several work windows and have sufficient desk depth. The named variant is a 31.5-inch 4K UHD IPS monitor with USB-C; check the connection’s video and charging functions, required cable and your viewing distance before planning a one-cable setup.

A straightforward second-screen option to assess for everyday work. Check that its video input and the cable you will use match your computer, and that its stand can place the screen at a suitable height on your desk.
No: a direct cable can be enough if the laptop has a video output that matches the monitor input. Consider a dock or USB-C hub monitor if you also want compatible laptop charging or peripheral connections, and check each function against your computer.
No: the connector alone does not establish video support. Check your exact computer’s specifications and the cable or adaptor documentation; Apple Support, for example, specifies DisplayPort Alt Mode or the applicable Thunderbolt standard for relevant Mac display adaptors.
Choose Extend if you want the monitor to add desktop space for separate windows; Duplicate shows the same content on both screens. Microsoft Support explains how to identify and arrange connected displays in Windows display settings.
Position it so you can view it comfortably without an awkward desk layout. The Health and Safety Executive describes a standard position with the top of the screen around eye level and the display about an arm’s length away; check that the stand, desk and keyboard arrangement let you achieve a workable position.
