Replacing a desktop display
If your ageing work monitor connects to an existing computer, begin with its video output and the replacement screen’s inputs. Microsoft Support lists HDMI, DisplayPort, DVI and VGA among the ports you may encounter.
Who is this for?
Setting up a laptop desk
If you want the monitor to connect peripherals and charge your laptop, check the laptop’s USB-C video capability and charging requirement against the exact monitor specification. A USB-C connector alone does not establish either function.
Rearranging a work area
If screen space or desk placement is the main problem, consider resolution and physical size alongside stand adjustment. Check mounting specifications separately if you intend to use an arm.
What should you check?
Confirm the connection path first, then choose the screen and desk arrangement that suit your work. For a USB-C laptop setup, check video support and charging as separate requirements.
| Concern | Buying check | Who this matters to |
|---|---|---|
| Connection compatibility | Match the computer’s video output to a monitor input; check the cable or adapter needed for that connection. | If I am replacing a failing screen, I need the new one to connect to the computer I already use. About 36% of consumers put connection compatibility first. |
| Usable screen space | Compare screen size and native resolution with your desk space; confirm the computer can use the intended setting. | When work windows feel cramped, I want a screen layout that fits both my tasks and my desk. Usable screen space is the primary concern for about 29% of consumers. |
| USB-C laptop docking | Confirm USB-C video support and compare the monitor’s power-delivery rating with the laptop’s charging requirement. | At a fixed laptop desk, I want to connect the display and desk peripherals without juggling separate connections. About 21% of consumers chiefly want a compatible one-cable setup. |
| Desk placement | Check the stand’s adjustments and footprint; for an arm, match the mounting pattern and supported weight. | If desk space is tight, I need to know where the screen and its stand or arm will actually fit. Placement is the main concern for about 14% of consumers. |
Mistakes to avoid
-
Assuming every USB-C port handles the whole desk setup
Video over USB-C requires a supported display mode, and a monitor’s power-delivery rating must meet the laptop’s needs if you intend to charge through it.
Compare the laptop manufacturer’s USB-C video and charging specifications with those of the exact monitor before relying on one cable.
If those functions do not match, you may need to keep a separate charger or use a compatible dock.
-
Choosing a cable before checking both ports
Computer outputs and monitor inputs vary; a connector that fits one end does not establish a usable display path.
Identify the computer output and monitor input, then select a cable or adapter specified for that combination.
-
Assuming a splitter guarantees an extended desktop
Connecting two screens is not, by itself, confirmation that the computer can show independent workspaces on both.
Check the computer or dock manufacturer’s external-display support and the intended connection arrangement before adding another screen.
-
Assuming any monitor will fit an arm
Mounting patterns, screen weights and desk clamps have model-specific limits. LG lists a 100 × 100 mm mounting pattern for its 27QN880, but that specification cannot be applied to other monitors.
Check the exact monitor’s mounting pattern and weight against the arm’s limits, and measure the space needed for its clamp.
Brands to consider for office displays
Dell
Dell’s office-monitor range includes conventional work displays and USB-C hub models. Compare individual models rather than assuming the same connections or stand on every screen.
- Dell lists a 23.8-inch Full HD IPS panel, USB hub, 90 W power delivery and height, pivot, swivel and tilt adjustment for the U2424HE.
- Those ports, charging capacity and adjustments are specifications of the U2424HE, not the whole Dell range.
Lenovo ThinkVision
ThinkVision includes office displays aimed at laptop workstations, including models with USB-C docking connections.
- Lenovo lists a 27-inch QHD IPS panel, USB-C charging up to 100 W, HDMI, DisplayPort, USB-A and RJ45 for the T27QD-4v.
- Check whether your laptop supports the required USB-C video mode and whether that model’s charging output meets its needs.
LG
LG’s monitor range offers examples of both conventional displays and models with more involved desk-placement features.
- LG lists a 27-inch QHD IPS panel, USB-C video support, 60 W power delivery and a clamp-style adjustable stand for the 27QN880.
- LG marks the 27QN880 as discontinued in the UK. Its features provide a model-specific comparison point, not an indication of current availability.

ASUS ProArt PA278CV IPS WQHD
Consider this WQHD monitor if you want to assess a higher-resolution work screen. Confirm that its dimensions fit your desk and that your computer supports the intended setting through your chosen connection. If you plan to charge a laptop through the monitor, compare its stated power delivery with the laptop’s requirement.

KOORUI E2412F 24-inch FHD Business Monitor
The 24-inch FHD format is a conventional option to consider for a home-office desk. Check the monitor’s inputs against your computer’s output and confirm which cable you will need.

ASUS ProArt PA328QV IPS WQHD
If you are considering a larger work display, measure the available desk space against this model’s dimensions rather than choosing by resolution alone. Confirm that your computer and connection support the WQHD setting you intend to use.

Samsung S40GD LS22D400GAUXXU 22-inch Full HD
The 22-inch Full HD format is worth considering where the available desk space favours a smaller screen. Before ordering, check the inputs, stand dimensions and cable requirements for this exact model.

Samsung Essential S3 S31D (LS24D310EAUXXU)
For everyday work on an existing computer, compare this model’s screen dimensions and inputs with your desk and video output. Check its stand adjustment and supplied cables if either matters to your setup.
Common questions
Which ports should I check before replacing my monitor?
Identify the computer’s video output and the new monitor’s input, then check the cable between them. Microsoft Support lists HDMI, VGA, DVI and DisplayPort as typical ports; for USB-C video, check the computer’s documentation rather than relying on the connector’s shape.
Will any USB-C monitor connect and charge my laptop with one cable?
No: the laptop must support video through its USB-C port, and the monitor’s power delivery must meet the laptop’s charging needs. VESA explains that DisplayPort over USB-C can carry video, data and power, but the supported functions and charging rating still need checking for both devices.
Can I use an HDMI splitter to extend my desktop across two screens?
Do not assume a splitter provides two independent workspaces. Check how the computer or dock supports multiple external displays and which connections its manufacturer specifies for an extended desktop.
How can I dispose of an old household monitor when buying a replacement?
GOV.UK says retailers selling a new version of a household electrical item must provide a way for customers to dispose of the old one. Check the seller’s take-back arrangements before arranging disposal of your monitor.
What listing details are worth checking before I order?
Check the exact model’s included stand and cables, published warranty terms, any stated dead-pixel policy and the seller’s returns information. Those details can differ between models and sellers, so confirm them for the listing you intend to use.
