Who might need a second monitor?

People working at a small desk

If a laptop, keyboard and notes already fill the work surface, the monitor’s width and stand footprint matter as much as its screen size. An arm is another possibility, provided the monitor and desk can accommodate it.

Laptop users seeking fewer cables

A USB-C monitor may connect a laptop to a display and peripherals, and may charge it. Those functions depend on the particular computer port and monitor, so check video support and the stated power-delivery output rather than relying on the connector shape.

People using a screen for long sessions

For extended work or study, consider where the additional screen will sit alongside the desk, chair and input devices. Height and tilt adjustment can offer more positioning choices, but no single monitor feature replaces a workable overall setup.

What matters when choosing one?

Start with desk fit and a connection your computer supports. Then consider positioning and how much extra visible workspace you need; a larger panel or a USB-C connection is useful only if those basics work for your setup.

Concern What to check Who this matters to
Desk fit Measure the available width and depth against the panel and stand. If considering an arm, check the monitor mount, weight and desk clamp. I need a second screen without crowding my laptop and working area; roughly 31% of consumers put desk fit first.
Connection and charging Match the computer’s documented video output to the monitor input and intended cable. For USB-C laptop charging, compare the monitor’s power-delivery rating with the laptop’s requirements. I want the display to work with my existing computer, and perhaps charge my laptop through one cable; about 25% of consumers make connection and charging their primary concern.
Screen positioning Compare the stand’s height, tilt, swivel and pivot adjustments with the positions your desk permits. During long work or study sessions, I need to place the screen sensibly within my workstation; around 25% of consumers prioritise positioning.
Visible workspace Consider panel size and resolution, then check the resolution and refresh rate your computer supports through the intended connection. I mainly want more documents or application windows visible at once; roughly 19% of consumers put extra visible workspace first.

What should you avoid overlooking?

  • Assuming every USB-C port carries video and charging

    USB-C describes the connector, not every capability behind it. Video output depends on the computer port and monitor connection, while laptop charging depends on the monitor’s power-delivery output.

    Check the exact computer model’s external-display guidance and compare it with the monitor’s stated USB-C video mode and charging wattage.

    A separate cable, adapter, dock or the laptop’s own charger may still be needed.

  • Choosing a large panel before measuring the desk

    A screen can fit across the desk yet leave too little depth for its stand, cables, laptop or input devices. Which? discusses smaller monitors for limited spaces and larger displays for home offices.

    Measure the usable desk area, including room behind the stand for connections, before deciding on screen size or an arm.

    If the stand obstructs the work area, rearranging the desk or using a compatible arm may be necessary.

  • Assuming a monitor arm fits any screen and desk

    Mounting pattern, monitor weight and depth, and the desk clamp all affect whether an arm is suitable.

    Compare the exact monitor specifications with the arm’s stated mounting, load and clamp requirements before choosing either item.

  • Relying on monitor adjustment alone for long sessions

    A height-adjustable stand offers positioning flexibility, but it does not settle how the screen works with the chair, desk, input devices and lighting. The Health and Safety Executive considers the wider workstation for workers covered by display screen equipment rules.

    Plan the whole setup. If those rules apply to your home working, raise persistent setup concerns through your employer’s workstation assessment process.

Brands to consider

These ranges illustrate different connection and positioning options; check the specifications of the particular model rather than assuming a feature applies across a brand.

Dell

Dell’s UK monitor range includes height-adjustable and USB-C models for comparing conventional video connections with a monitor-hub setup.

  • Dell UK lists models with height, pivot, tilt and swivel adjustment; its S2725DC listing states USB-C DisplayPort Alt Mode and power delivery up to 65 W.
  • Check the exact Dell model’s inputs, charging output and stand adjustments before planning a one-cable or long-session setup.

BenQ

BenQ’s home-office range includes USB-C models such as the GW2786TC for laptop connections and adjustable desk setups.

  • BenQ’s GW2786TC specifications state 65 W USB-C power delivery, additional USB-A ports and height, pivot, tilt and swivel adjustment.
  • For multiple displays, check the computer as well as the monitor: BenQ notes that Mac daisy chaining uses a Thunderbolt route rather than assuming the same behaviour through this monitor alone.

LG

LG’s Ergo range includes a C-clamp stand option for buyers considering a different way to position a screen on the desk.

  • LG lists the 32UN880K-B with a 31.5-inch 4K IPS panel, an adjustable C-clamp stand and USB-C power delivery up to 60 W.
  • Check that your desk accepts the clamp and has room for that particular display; those specifications do not describe every LG monitor.

Joybuy monitors for different setups

These choices cover smaller desk displays, larger home-office options and a portable second screen. Match the screen’s physical fit and connection to your own computer before choosing between them.

Dell P2425 24-inch monitor

Dell P2425 24-inch monitor

Consider this 24-inch model when you want a separate desk display without starting with a larger panel.

Measure the stand’s footprint as well as the screen width. If refresh rate or USB-C video and charging matter to you, confirm those details for the exact P2425 before ordering.

ASUS ProArt PA278CV IPS WQHD monitor

ASUS ProArt PA278CV IPS WQHD monitor

Consider this WQHD model if you have space for a larger home-office display and want to compare screen positioning options.

Its name specifies an IPS panel. Check its full dimensions against your desk and confirm the USB-C power-delivery output against your laptop’s requirements if you expect the monitor to charge it.

Frequently asked questions

Will any USB-C laptop port run and charge a second monitor?

No. Check the exact laptop port for external-display video support, then check the monitor’s USB-C video mode and power-delivery output if you also want it to charge the laptop. As the Video Electronics Standards Association explains, DisplayPort Alt Mode enables video over USB-C in compatible implementations; the connector alone does not establish compatibility.

What should I check before connecting a monitor through a dock?

Check the computer’s output, the dock’s supported display configuration and the monitor’s input, including the resolution and refresh rate you intend to use. Apple Support notes that a Mac’s supported display count depends on its model and on the resolution and refresh rate of each display; check the documentation for your particular computer rather than assuming a dock increases its display limit.

Can I daisy-chain the BenQ GW2786TC with a Mac?

Do not assume that its DisplayPort or USB-C daisy-chain route will work with a Mac. BenQ states that Mac devices support daisy chaining through Thunderbolt, so check the exact Mac, monitor and any proposed Thunderbolt dock or other device before buying for a multi-screen setup.

How do I tell whether a monitor arm will fit?

Match the monitor’s VESA mounting pattern, weight and depth to the arm’s specifications, and check the desk against its clamp requirements. Ergotron, for example, specifies its LX slim-clamp arm for VESA 75 × 75 mm or 100 × 100 mm mounting and monitors weighing 3.2–11.3 kg; another arm may have different limits.

Do UK home-working rules require everyone to buy a second monitor?

No blanket requirement to buy a second monitor follows from the Health and Safety Executive’s guidance. UK display screen equipment duties apply to employers of qualifying workers who use display screen equipment daily for continuous periods of an hour or more, including some home workers. Where the rules apply, the employer must assess the workstation and address identified risks; a second monitor is not an automatic requirement for every worker or student.
