Choose a direct monitor connection when you need one external screen and your computer already has a compatible video output; it is usually the simplest route. Choose a USB-C monitor, dock or hub when one connection must also handle charging, peripherals, Ethernet or several displays, but check the computer’s video capability, display limits, charging needs and required resolution before buying. Portable monitors suit temporary spaces, while an arm or stand is useful only when it improves the screen position at your workstation.
For people who want a larger screen for documents, video calls or study and need to choose between a direct display connection, a USB-C monitor with charging, or a dock. The key question is whether one screen is enough or whether charging and peripherals should also run through one cable.
For people moving between a home office, study area and kitchen table, or who need an extra screen that can be packed away. Portability, physical connection options and easy placement matter more here than building a permanent multi-device desk.
For people considering two or more displays, higher-resolution output or a dock-based arrangement for editing, large spreadsheets and multitasking. Check the exact computer model’s supported display count, resolution and refresh-rate limits before planning the setup.
Choose it when: One external screen is enough and the computer already has a matching video output.
Bear in mind: It does not automatically add charging, Ethernet, peripherals or further display outputs.
Choose it when: You want to connect a compatible laptop to power, a display and desk accessories with fewer cables.
Bear in mind: The laptop’s own display and charging limits still apply.
Choose it when: The extra screen needs to move between rooms, travel with you or be stored after use.
Bear in mind: USB-C video may require a video-capable port, while some models need separate power or software.
| Priority | What to check | Your needs |
|---|---|---|
| Video connection compatibility | Check the computer’s exact output port and the monitor’s input. For USB-C, confirm video output such as DisplayPort Alt Mode, Thunderbolt or USB4 rather than relying on connector shape alone. | I need the screen, cable or adapter to work with the ports already available on my laptop or desktop. |
| Single-cable desk setup | Compare the monitor or dock’s upstream power delivery with the laptop’s recommended charger rating. Confirm that the chosen USB-C cable supports the required video, data and power arrangement. | I want to connect video, charging and desk accessories with fewer cables when I sit down to work. |
| Multi-monitor expansion | Check the computer’s documented independent-display limit, then the dock technology and stated resolution and refresh-rate configuration for each output. | I need separate extended desktops for spreadsheets, editing or multitasking, not duplicate images on two screens. |
| Flexible workspace use | Consider portable-monitor size, weight, stand arrangement and available HDMI or USB-C inputs. For an arm, check its adjustment range, screen mounting compatibility and desk-clamp fit. | I need extra screen space without leaving a large permanent setup on a small desk or shared table. |
| Screen position | Assess viewing height, desk depth, monitor weight and mounting surface before choosing a riser or arm. The Health and Safety Executive advises considering whether home equipment is suitable for the actual workstation. | I want a screen position that remains comfortable for regular work or study, rather than choosing solely by panel size or port count. |
USB-C ports can support different functions. ASUS distinguishes DisplayPort Alt Mode video from DisplayLink-based USB display operation, and plug-and-play video requires compatible functions on both the computer and monitor.
Find the exact laptop model’s technical specification and confirm video output on the intended port before matching it to a monitor, dock or adapter.
An unsuitable adapter, hub or portable monitor may not work in the intended plug-and-play mode.
Apple states that simultaneous display count depends on the Mac model, resolution and refresh rate. Microsoft also notes that a graphics adapter may not support more than one external monitor.
List the required number of independent screens, resolution and refresh rate, then confirm that exact computer-and-dock configuration in the relevant documentation.
A dock can provide duplicate output or an unusable second-screen arrangement when the computer cannot support the planned configuration.
Charging output is model-specific. Dell UK and LG UK list 90W power delivery on particular monitor models, but a monitor or dock may supply a different amount of power.
Compare the monitor or dock’s upstream power-delivery rating with the laptop manufacturer’s recommended charger rating, especially for the intended workload.
You may need to keep the original laptop charger connected or experience slower charging under load.
The Health and Safety Executive says home workers may not need additional office equipment if their existing equipment is suitable. A mount cannot solve every viewing-position issue.
Check screen height, viewing position, desk depth, monitor mounting pattern, monitor weight and the desk’s clamp or mounting surface before choosing an arm or riser.
A mount that does not fit the monitor or desk may not improve the screen position.
A relevant option for permanent home desks because Dell UK sells USB-C hub monitors that combine a display with charging and connectivity features.
A relevant option for buyers who need a separate USB-C or Thunderbolt dock to connect displays, charging and peripherals through one laptop connection.
A relevant option for portable-display buyers who need an extra screen for hybrid work, study or a small temporary workspace.
A relevant option for users seeking an all-in-one USB-C monitor that can combine a larger high-resolution screen with laptop charging.

A fixed external-monitor route for a regular desk where a 31.5-inch 4K screen and several video inputs suit documents or creative tasks.
31.5-inch 4K QD-OLED panel; 165Hz; DisplayPort 1.4; two HDMI 2.1 inputs; USB-C with stated 65W charging; USB hub; height, tilt and swivel adjustment; VESA mounting.
Check that the computer supports the intended 4K resolution and refresh rate. USB-C video and 65W charging depend on laptop capability and charging needs, while the 6.5kg screen needs adequate desk space or suitable VESA support.
No image available
A dock option for connecting displays, charging and desk peripherals through a compatible USB-C laptop connection.
USB-C Alt Mode host connection; two HDMI 2.0 outputs stated for two 4K UHD displays at 60Hz; 100W power-delivery pass-through; Gigabit Ethernet; USB-A ports; SD and microSD readers.
The computer’s own display count, resolution and refresh-rate limits still apply. Check USB-C video support, operating-system compatibility and whether a suitable external 100W-plus power adapter is included or available.
No image available
A compact portable-display option for temporary study, travel or a small workspace that needs an extra movable screen.
14-inch Full HD display; 60Hz; 10-point capacitive touch panel; 180-degree adjustable stand; VESA compatibility; stated 100% sRGB coverage.
One-cable USB-C use requires video output from the connected device; otherwise separate monitor power is needed. Touch operation also depends on compatible device and operating-system support.
No image available
A regular-desk monitor option for documents and calls where a 24-inch screen and several stated connection types are useful.
24-inch Full HD IPS display; 100Hz; HDMI, DisplayPort, USB-C and VGA connectivity; height, tilt and swivel adjustment; matte surface; stated 99% sRGB coverage.
Check the function of the USB-C port and cable requirements before choosing a USB-C connection. Also confirm that the computer has a matching video output and verify mounting compatibility if an arm is required.
Check the laptop manufacturer’s specification for video output over that specific USB-C port, commonly described as DisplayPort Alt Mode, Thunderbolt or USB4 capability. Also check the monitor’s USB-C input, required cable and charging output, because the connector shape alone does not confirm video support.
Usually not if the computer already has a compatible HDMI, DisplayPort, Thunderbolt or video-capable USB-C output and you need only one screen. A dock is more useful when you also want charging, keyboard and mouse connections, Ethernet, storage or additional displays through one connection.
Not automatically. Apple states that external-display capacity depends on the Mac model, display resolution and refresh rate, while Microsoft advises checking the graphics manufacturer’s supported display count. Check the laptop and dock specifications as one combined setup.
Not generally on Windows. Microsoft states that a display splitter duplicates the same signal rather than creating two independent signals. If you need separate extended desktops, choose a computer and dock arrangement explicitly documented to support multiple external displays.
No. The Health and Safety Executive says home workers may not need office furniture or equipment if their own setup is suitable. Consider an arm or stand when the actual workstation needs a different screen position, then check monitor mounting compatibility, supported weight and desk suitability.
