Choose a screen size and resolution that make your usual documents comfortable to view, then check that the stand and footprint suit your desk. A conventional video connection may be enough; for USB-C charging or a monitor hub, check the laptop, monitor and cable specifications together, as Dell Support advises. If you want a second screen, confirm your computer’s external-display limit before choosing the setup.
If you want room to read, write or compare windows without replacing your computer, compare resolution and text scaling as well as screen size. Dell’s P2725D specifications and Microsoft’s Windows scaling guidance are useful reference points.
If you regularly connect and disconnect a laptop, you may want a compatible USB-C setup for video, charging and possibly peripherals. Dell Support’s USB-C guidance and BenQ’s GW2790QT specifications illustrate why the laptop’s port and the monitor’s power delivery need checking.
If the display needs to fit a compact desk or be positioned for extended use, consider the stand and footprint as well as the panel size. The Health and Safety Executive gives screen-positioning guidance, while the exact adjustment available depends on the monitor model.
Start with the workspace you need, then check the computer connection and whether the screen can be positioned comfortably at your desk.
For consumers choosing an external display for desk-based work, study or document viewing, the table links each main priority to a practical check.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Usable space and readable text | Compare screen size, native resolution and text scaling at your usual viewing distance. Dell lists 2560 × 1440 for its 27-inch P2725D; Microsoft explains Windows scaling controls. | If I work with documents or spreadsheets, I want useful workspace without text becoming uncomfortable to read. Roughly 31% of consumers put readable workspace first. |
| Laptop connection and charging | Check that the computer supports video through the port, and compare the monitor’s power delivery and cable with the laptop’s charging needs. Dell Support advises checking port features; BenQ lists 65 W power delivery for the GW2790QT. | If I connect my laptop at a desk, I want the planned cable to provide the functions I need. Roughly 25% of consumers prioritise connection and charging. |
| Desk fit and positioning | Measure the desk and stand footprint, then check the model’s adjustment or mounting options. The Health and Safety Executive suggests positioning the screen about an arm’s length away; Dell specifies 150 mm of height adjustment for the P2725D. | If my desk is compact or I use the screen for long sessions, I need space to position it comfortably. Roughly 25% of consumers prioritise desk fit and positioning. |
| Multiple-screen layout | Check the exact computer’s external-display support and available outputs before planning the arrangement. Apple’s published specifications show that limits vary by model; Windows includes controls for arranging detected displays. | If I need separate documents or applications visible at once, I want to know the computer can support my planned layout. Roughly 19% of consumers prioritise a multiple-screen workflow. |
USB-C video support and power delivery are separate, model-specific capabilities, so the connector shape alone does not establish that a one-cable setup will work as intended.
Check the laptop’s port specification and charging requirement against the monitor’s input and power-delivery rating, and make sure the cable supports the planned connection.
A separate video adapter, cable or charger may still be needed.
A screen that does not fit the desk or cannot be placed at a workable distance and height may not suit the setup, even if its display specifications meet your needs.
Measure the desk and stand footprint, then check the exact model’s adjustment or mounting details before choosing where it will sit.
If the supplied stand cannot be positioned suitably, you may need a compatible mount or another positioning arrangement.
Support for multiple external displays varies by computer model, so an available port does not by itself confirm that the planned arrangement is supported.
Check the exact computer’s specified external-display limit before planning the layout.
An adapter or another display will not resolve a mismatch with the computer’s display limit.

No; the connector shape alone does not confirm video or suitable charging support. Check the laptop’s documented USB-C video function, its charging requirement, the monitor’s rated power delivery and the cable. Apple’s published laptop specifications illustrate why these capabilities need checking by model.
The Health and Safety Executive suggests positioning the top of the screen around eye level and the display about an arm’s length away. Its guidance for prolonged laptop use also describes using a separate keyboard and mouse with an elevated laptop screen, or a separate display; it does not require every private buyer to purchase a particular stand.
Connect the screen, then use Settings > System > Display to identify and arrange detected displays. Windows also provides scaling controls if text and apps are uncomfortable at the chosen resolution, but the computer still needs to support the intended display setup.
The Health and Safety Executive does not establish a blanket requirement for every private buyer to purchase an external monitor. Its guidance says the Display Screen Equipment Regulations can apply to people who work at home permanently or for the long term, and describes employers’ assessment duties for qualifying display-screen users.
