Desk-based remote and hybrid workers
If documents, messages and applications stay open throughout the working day, a fixed screen may suit a regular desk. Check its connection to the laptop and consider the whole workstation, not just the display.
Who is each setup for?
Mobile hybrid workers and freelancers
If you move between work locations, compare a portable screen’s size and carrying weight with the workspace it gives you. Check that your laptop can send video through the screen’s required input before choosing one.
Workers connecting several desk devices
A monitor hub or dock can bring display, charging and peripheral connections together. Its available sockets do not, by themselves, establish how many external displays your laptop can run.
What should you check before buying?
Start with the laptop’s display capabilities, then choose the screen format and connection arrangement that fit where you work.
| Priority | What to check | Your needs |
|---|---|---|
| Laptop compatibility | Check the exact model’s video outputs and supported external-display count. Confirm the intended resolution and refresh rate, particularly for multiple screens: Apple says MacBook Pro limits depend on the model and display configuration. | I want the extra screen to work alongside any displays I already use, at the resolution I plan to select. |
| Screen location | Compare a fixed monitor’s desk space with a portable display’s dimensions and weight. For a USB-C portable screen, match its stated video-input mode to the laptop’s output. | Will this screen stay at one desk, or do I need to carry it between work locations? |
| Desk connections | Check whether the laptop and display can connect directly. If you need a dock or monitor hub, match its video technology, charging requirements and peripheral ports to the laptop; Apple says a hub does not increase a MacBook Pro’s maximum supported display count. | I would rather connect charging and desk accessories together, but only if the arrangement supports the screens I need. |
| Cable or adapter | Identify the laptop’s video output and the monitor’s input, then choose a compatible connection. A matching connector shape alone does not establish USB-C video support. | If one screen connects directly, I may not need a dock just to add that display. |
| Workstation fit | Consider screen position, equipment, furniture, the work and individual requirements. The UK Health and Safety Executive says an individual assessment is needed where display screen equipment rules apply to home or hybrid work. | I need the added screen to fit the way my workstation is arranged, rather than relying on screen size alone. |
What can go wrong?
-
Assuming every USB-C port carries video
A USB-C connector alone does not establish support for the video mode required by a portable monitor. ASUS specifies DisplayPort Alt Mode for the ZenScreen MB166C.
Check the exact laptop port specification against the monitor’s input requirement before ordering.
-
Expecting a dock to bypass laptop display limits
A dock can organise connections without increasing the computer’s supported number of external displays. Apple states this limit for MacBook Pro models even when a supported hub or daisy chain is used.
Confirm the laptop’s display count, resolution and refresh-rate limits before choosing a dock and monitors.
-
Choosing by screen specification alone
A compatible monitor does not settle questions about its position or the rest of the workstation. The UK Health and Safety Executive says display screen equipment assessments consider equipment, furniture, work conditions, tasks and individual needs.
Where the rules apply to home or hybrid work, use the workstation assessment to consider what equipment and placement are appropriate.
Relevant brand references
These model examples illustrate different screen arrangements; their connections and features should not be assumed to apply across each brand’s range.
Dell
The Dell Pro 27 Plus 4K USB-C Hub Monitor P2725QE illustrates a fixed-desk monitor with hub functions.
- Dell specifies video, data, Ethernet and up to 90 W power delivery over USB-C for the P2725QE.
- Check the host laptop’s connection support. Dell says daisy chaining multiple displays through one cable requires Thunderbolt connectivity and notes limitations for select M-series chips.
ASUS
The ASUS ZenScreen MB166C is a portable second-screen example for a compatible laptop.
- ASUS specifies a 15.6-inch, 1920 × 1080 anti-glare IPS screen weighing 0.78 kg.
- Its USB-C video input requires DisplayPort Alt Mode; a USB-C socket without that capability is not enough.
Lenovo
The Lenovo ThinkVision M14d is a compact portable-display example for changing work locations.
- Lenovo specifies a 14-inch, 2240 × 1400 screen, two USB-C ports, up to 65 W power pass-through and a 600 g weight.
- Check the notebook’s supported USB-C display mode and power requirements for the intended connection.
Joybuy options for extra screens
These options cover fixed monitors, portable displays and a dock for laptop-based work. Match each one to your laptop and the location where you will use it; the dock is a connection accessory, not an extra screen.

Targus USB-C Universal Dual HDMI 4K dock, 100W pass-through
Consider this dock when connecting two HDMI displays is part of your desk plan. Its dual-display connection does not establish your laptop’s supported display count; check the host requirements and whether the external power adapter called for in the product information is included.

ASUS ZenScreen MB249C IPS USB-C display
Consider the MB249C if you change desks but want a larger secondary screen. Check its size and carrying weight against your journey, confirm your laptop’s intended video connection and check whether the required power adapter is included for UK use.

ASUS ZenScreen MB166C 15.6-inch Full HD monitor
A portable second-screen option for work across locations. ASUS specifies a 0.78 kg net weight and a USB-C input using DisplayPort Alt Mode; confirm that your laptop’s USB-C port supports that video mode.

iiyama ProLite XUB2792UHSU-B6 27-inch 4K monitor
A fixed 27-inch 4K screen for a regular desk. Before choosing a cable or hub, confirm the monitor’s input requirements and whether your laptop can drive the intended resolution alongside any other display.
Common questions
How can I tell whether my laptop supports an extra monitor?
Check the exact laptop model’s video outputs and supported number of external displays at your intended resolution and refresh rate. If a connected screen does not appear in Windows, Microsoft Support describes a Detect option under Multiple displays; Apple says MacBook Pro display limits depend on the model and display configuration.
Will any USB-C port work with a portable monitor?
No. The port must support the video mode the monitor requires. For example, ASUS specifies DisplayPort Alt Mode for the ZenScreen MB166C, so check your laptop’s port specification rather than relying on the connector shape.
Can a dock increase my laptop’s external-display limit?
Do not count on it. Apple says a supported hub or daisy chain does not increase a MacBook Pro’s maximum number of external displays. Check your laptop’s own limit before matching a dock to the displays you intend to connect.
Does adding a monitor settle workstation suitability?
No. For UK workstations where display screen equipment rules apply, the Health and Safety Executive says an individual assessment should consider equipment, furniture, work conditions, the task and the worker’s requirements. Consider the screen’s position as part of that wider setup.
