Choose a desktop monitor if the screen will stay at a regular desk and you can position it comfortably; consider a portable monitor if you need to move or put away the extra display. A TV is another possibility only if its connection and physical placement work for your desk. Whichever screen you choose, check your computer’s supported video output and external-display limit before matching its ports, cable and position to the new display.
The useful choice depends on where the screen will sit, how often it will move and what your existing computer can connect to.
If documents, web tools or classes regularly compete for space on one display, consider an additional screen alongside the whole desk layout. Which? discusses monitors for home offices and study areas; the Health and Safety Executive advises assessing screen position as part of the workstation.
A familiar-looking port does not settle which display and cable to buy. VESA says USB-C video through DisplayPort Alt Mode requires support from the source device, while Apple says the number of external displays a Mac supports depends on its model.
When a permanent monitor would occupy space needed for other activities, a portable display may be easier to move or put away. A TV is worth considering only if its connection and viewing position also suit the intended desk setup.
Consider it: for regular work or study at a dedicated desk where the screen can stay in position.
Trade-off: it occupies permanent desk space, and its supplied stand may not provide the position you need.
Consider it: when the second screen needs to move between temporary or shared workspaces.
Trade-off: portability does not establish that its connections or screen position will suit prolonged desk work.
Consider it: if multipurpose use matters and the TV can be connected and placed appropriately at the workstation.
Trade-off: an HDMI input alone does not make a TV practical at your desk; assess its placement and viewing distance.
| Priority | What to check | Your needs |
|---|---|---|
| Video connection | Confirm the computer’s video-output capability, then match it to the display input and cable. VESA says USB-C DisplayPort Alt Mode requires source-device support; an adapter cannot supply a video mode the computer lacks. | I want to know that my existing computer can actually drive the screen, not just that the connectors look alike. |
| Screen position | Check desk depth, stand footprint and available adjustment or compatible mounting. The Health and Safety Executive advises placing the top of the screen around eye level, about an arm’s length away. | There needs to be room for the screen, keyboard and mouse without an awkward viewing position. |
| Space and movement | Compare the space a fixed monitor and stand will occupy with where a portable display could be used or stored. For a TV, check its input and whether its dimensions permit a workable desk position. | If I share the desk or work in different rooms, I need a screen arrangement I can live with between sessions. |
| Extended desktop | Check the exact computer’s supported external-display count and intended resolution and refresh rate. Apple says Mac support varies by model; Microsoft Support advises checking connections to the PC or dock when setting up multiple monitors. | I want windows on an additional desktop, with the displays arranged to match where they sit. |
USB-C describes the connector, not all the capabilities behind it. VESA says a USB-C video connection using DisplayPort Alt Mode depends on source-device support.
Check your computer’s exact video-output specification, then match the display input and cable or adapter. Check any charging requirement separately.
Matching the confirmed ports may also require a compatible cable, adapter or dock.
A larger diagonal does not ensure a workable desk layout. The Health and Safety Executive advises considering the screen’s height and viewing distance as part of the whole workstation.
Measure the usable desk space and stand footprint. If the supplied stand cannot place the screen appropriately, check a compatible mounting arrangement before buying.
A different stand or desk arrangement may be needed to achieve a workable position.
A dock is part of the connection chain, not a substitute for external-display support. Apple says the number of displays a Mac can use depends on the exact model and display settings.
Confirm the computer’s supported display count and output modes before selecting a dock for a second or further screen.
A possible computer-to-TV connection does not settle whether the TV can be positioned comfortably for regular work. The Health and Safety Executive’s workstation guidance still matters when using it as a display.
Check the computer output, TV input and required cable, then assess viewing distance, glare and available desk space.
These brand examples point to features to check on an exact model; a feature on one monitor should not be assumed across its range.
Dell UK lists desk monitors with different connection options, including HDMI, USB-C and Thunderbolt.
Samsung’s UK ViewFinity range includes desktop displays with USB-C connectivity features.
BenQ is a reference for comparing stand adjustments on a conventional home-office display.
ASUS presents a portable-monitor range for screens that move between workspaces.
These options include desktop monitors for a fixed workstation and portable monitors for a screen that needs to move. Match any candidate to your computer’s output and the space where you will use it.

A desktop-monitor option for a regular work or study desk. Its name specifies an IPS WQHD display; check the exact inputs, stand dimensions and adjustment range against your computer and workspace.
No image available
A 27-inch desktop display to consider where you have room for a permanent second screen. The product name specifies 4K UHD and a 16:9 format; confirm that your computer supports the intended connection and display settings, and check the stand’s fit on your desk.
No image available
A 22-inch desktop-monitor option if a larger screen would be difficult to place. Its name specifies Full HD; check the actual stand footprint and inputs before deciding whether it fits your desk and computer.
No image available
A portable option for a shared or temporary workspace. Its name specifies a kickstand and USB-C and HDMI connections; match the intended connection to your computer’s video output, and check how the screen will be powered and positioned.
No image available
A portable Full HD option for an extra screen that can move with your workspace. Check the model’s required video connection, cable and power arrangement against your computer, as well as the screen position available for longer sessions.
No: the connector shape alone does not confirm video output. VESA says a USB-C DisplayPort Alt Mode connection needs support from the source device, so check your exact laptop specification before choosing the display input and cable or adapter.
No. Apple says external-display support depends on the Mac model, and the number usable at once also depends on the connected displays’ resolution and refresh rate. Check your exact Mac’s specifications before selecting a monitor or dock.
Position it within a workable arrangement for the screen and keyboard. The Health and Safety Executive advises placing the top of a screen around eye level and about an arm’s length away; check whether your desk and stand allow that position.
Possibly, if your computer can connect to the TV and the TV can be placed appropriately for your work. Check the output, input and cable first, then assess viewing distance and the whole desk arrangement using the Health and Safety Executive’s workstation guidance.
