Choose a fixed external monitor if most of your work happens at one home desk, or a portable monitor if the second screen needs to travel with you. A dock is useful when you also want to connect charging and peripherals at the desk; if you only need one display, a compatible cable or adapter may be enough. Whichever route you choose, check your laptop's video output, supported display modes and charging requirements before buying.
Who each setup suits
The useful distinction is where you need the extra screen and how much else you want to connect. A monitor adds display space; a dock or adapter connects equipment but does not provide a screen.
People working mainly at one home desk
If you regularly keep documents and communication tools open together, a fixed external monitor gives you a second workspace without having to carry it between locations. Consider a USB-C hub monitor if connecting peripherals and charging through the display also matter, but check those functions against your laptop.
People moving between workspaces
A portable monitor keeps the second-screen option available away from your home desk. Check its connection method against your laptop before relying on a single USB-C cable: ASUS Support distinguishes ports that carry video from USB display methods that require a driver.
People unsure what their laptop can connect
Start with the exact laptop model rather than the shape of its sockets. Its video-capable ports and external-display limits determine whether a direct cable, adapter, monitor or dock can deliver the setup you want. Apple Support, for example, advises checking Mac-model display limits as well as cable and adapter capability.
What matters when choosing
Decide whether your primary need is a permanent workspace, a quicker desk connection, a screen you can carry, or a way to connect one existing display. Then check the laptop and connection requirements for that route; a dock cannot increase the number of external displays the laptop supports.

What to check |
Who this matters to |
| Permanent desk workspace |
Choose a suitable screen size and resolution, then check stand adjustment and the laptop's supported video output. |
If documents and calls compete for room on my laptop screen, I want a larger workspace that stays ready at my desk. Around 36% of consumers put that fixed-desk need first. |
| One-cable desk connection |
Check video support, the laptop's display limit and whether the monitor or dock's power delivery meets its charging requirement. |
When I return to my desk, I want to reconnect my display and peripherals without handling several plugs. Roughly 29% of consumers prioritise that connection routine. |
| A screen to carry |
Check the portable monitor's size, weight and stand, plus its required video connection and any driver requirement. |
If I work in more than one place, the second screen needs to come with me, even if it offers less display area than a fixed monitor. About 21% of consumers place portability first. |
| Connecting one display |
Match the laptop output and display input, including the cable or adapter's supported resolution and refresh rate. |
If I already have a display, I would rather establish whether my laptop can connect to it than add a dock I do not otherwise need. Around 14% of consumers make that direct connection their priority. |
Connection mistakes to avoid
-
Assuming every USB-C port carries video
A matching connector does not establish that a laptop can send a picture to a USB-C monitor. ASUS Support distinguishes direct USB-C video from display methods that require a driver.
Check the laptop's specification for DisplayPort Alt Mode or another video-capable connection, then match it to the exact monitor's requirements.
-
Expecting a dock to overcome a laptop's display limit
A dock adds connections, but it does not override the number of external displays or display modes supported by the laptop. Apple Support notes that these limits vary by Mac model.
Confirm your laptop model's supported display count and resolution and refresh-rate combinations before choosing a multi-display dock.
-
Assuming USB-C charging is sufficient for any laptop
Power-delivery ratings differ by monitor and dock model. A USB-C charging connection alone does not establish that it meets your laptop's requirement.
Compare the stated power-delivery wattage with the laptop manufacturer's charging specification.
You may still need to use the laptop's own charger at the desk.
-
Overlooking the cable or adapter's display capability
Apple Support advises that an unsuitable cable or adapter can leave an external display dark or running at a lower resolution or refresh rate.
Check the cable or adapter against your intended display mode and the laptop's supported output.
Relevant brands to consider
These brands illustrate different monitor routes, not a guarantee that every model in a range has the same connections. Compare the exact model and your laptop before choosing.
Dell
Dell offers fixed USB-C hub monitors and portable monitors for different workspace needs.
- Dell UK lists USB-C hub-monitor options with DisplayPort Alt Mode and power delivery of up to 90W.

Lenovo ThinkVision
The ThinkVision range includes fixed displays and portable second screens.
- Lenovo Support describes the portable ThinkVision M15 with two USB-C ports and power pass-through.
- Check laptop video compatibility and whether a portable-sized screen gives you enough room for your work.
ASUS ZenScreen
ZenScreen covers portable-monitor choices with differing connection methods.
- ASUS lists portable options using connections such as HDMI and USB-C.
- ASUS Support distinguishes direct USB-C video from driver-dependent USB display methods; check the specific monitor and laptop combination.

- LG UK lists the 32UN880K-B with a 31.5-inch 4K IPS panel, a C-clamp stand and USB-C power delivery of up to 60W.
- Check that the desk suits the stand and that 60W meets your particular laptop's charging requirement.

Common questions
Will any USB-C laptop port work with a USB-C monitor?
No: the connector shape alone does not confirm video support. ASUS Support says direct USB-C display use requires compatible video functions on the computer and monitor, while some other USB display methods require a driver. Check both devices' specifications for the method the exact monitor uses.
Do I need a dock for one external monitor?
Not if your laptop already has a compatible video output and you can connect it to the display with a suitable cable or adapter. Consider a dock when you also need a convenient desk connection for charging or peripherals, while still checking the laptop's display limits.
What should I check before connecting another display to a Mac?
Check the exact Mac model's supported number of external displays, video ports and display modes. Apple Support also advises matching the cable or adapter to the intended resolution and refresh rate; an unsuitable connection can leave the display dark or operating at a reduced setting.
How do I use a second monitor as extra space in Windows?
Select an extended desktop rather than a duplicated image after connecting the monitor. Microsoft Support directs Windows users to the display settings to identify and arrange connected screens; check the selected resolution and layout there as well.
