For a regular desk, start with a desktop monitor connected directly to a compatible laptop; if the second screen needs to travel with you, consider a portable monitor instead. Add a USB-C or Thunderbolt dock when you also want to connect charging and peripherals through one desk connection. Before buying, check the laptop’s video-capable ports, supported number of external displays and charging requirements against the complete setup.
If you mainly work from one desk and want documents, messages and applications visible together, assess a directly connected desktop monitor first. A USB-C hub monitor or dock becomes relevant when you also want to connect charging or peripherals.
A portable monitor is worth assessing when you need a second screen in more than one location. Check its exact video connection and power arrangement against the laptop you will carry.
If repeatedly connecting a display, power and accessories is the main inconvenience, consider a dock. The laptop’s supported display count and charging capabilities still determine which dock setup can work.
Decide where the screen will be used, then check the laptop’s display support before choosing a monitor, dock or adapter. A matching connector alone does not establish that the whole setup will work.
| Concern | What to check | Who this matters to |
|---|---|---|
| Laptop compatibility | Check the exact laptop model’s video-capable ports and supported external-display count at your intended resolution and refresh rate. | If my laptop cannot drive the screens I want, extra dock outputs will not settle the problem. Roughly 33% of consumers would put laptop compatibility first. |
| Fixed-desk workspace | Compare screen size and resolution for your desk, then match the monitor input to a supported laptop output. | When I work mainly at one desk, I want room to keep documents and communication visible without moving a screen between locations. Around 27% of consumers would make desk workspace their primary concern. |
| Portable second screen | Check the monitor’s dimensions, video input and power arrangement against the laptop and the locations where you will use it. | If I carry my work setup between locations, a screen I can take with me matters more than a permanent desk display. About 20% of consumers would prioritise portability. |
| One-cable desk setup | Match the laptop’s host connection and charging needs to the dock or hub monitor’s stated display modes and power output. | When I return to my desk, I want to reconnect the display, power and accessories with less plugging and unplugging. Approximately 20% of consumers would put connection consolidation first. |
A USB-C connector does not, by itself, establish that a laptop can send video to a portable monitor or adapter. ASUS Support advises checking whether the computer’s USB-C port has a video function.
Check the laptop manufacturer’s port specification and match its stated video capability to the screen or adapter’s required connection.
Multiple sockets on a dock do not establish that the laptop can drive the same number of displays. Microsoft Support notes that a graphics adapter may not support more than one monitor; Apple Support says Mac display support depends on the model.
Check the exact laptop and dock together, including the operating system and intended display modes, before planning a multi-screen desk.
A monitor or dock’s stated power-delivery output must be compared with the laptop’s charging requirement and its supported charging port. A power rating on the accessory alone does not establish adequate charging for that laptop.
Confirm both the accessory’s host-power output and the laptop maker’s charging specification.
If the connection does not meet the laptop’s charging needs, you may need to keep its charger connected separately.
ASUS portable-monitor examples use different input arrangements, including USB-C video and mini-HDMI. The chosen model’s connection and power needs affect whether it fits your laptop.
Check the exact monitor’s inputs, required cables and power arrangement before ordering.
Depending on that arrangement, using the screen may also involve carrying a separate cable or power supply.
Dell’s monitor range includes USB-C hub models for a fixed desk.
LG has desktop USB-C monitors relevant to a desk setup that combines a screen connection with laptop charging.
ASUS ZenScreen includes portable monitors for people who move their second screen between work locations.
These choices cover a multi-connection dock, desktop monitors, a display adapter and a portable screen. Pick the type that fits where you work, then confirm compatibility with your exact laptop before choosing a model.

Consider this dock for a fixed desk where you want display connections and laptop charging through the desk setup.
The product name specifies dual HDMI 4K and 100W Power Delivery Pass-Thru. Check the dock’s supported display modes against your laptop’s external-display limits, and compare its charging arrangement with the laptop’s requirements.

This desktop monitor is a choice to assess if you mainly need a screen at a regular work desk.
Its product name specifies an IPS WUXGA display. Match the intended video connection to your laptop; if you also want charging through the monitor, check the required port support and power output.
No image available
Consider an adapter when the laptop supports external video but needs different connectors for one display and desk accessories.
The product name lists 4K HDMI, VGA, Gigabit Ethernet and dual USB 3.0 ports. Check the laptop’s USB-C video capability and the intended display mode; do not assume HDMI and VGA can drive separate screens at once.

This desktop monitor is another option to assess for a stationary laptop workspace.
Its product name specifies an IPS WQHD display. Confirm a compatible video connection, and check the monitor’s charging output against your laptop’s requirements if one-cable charging matters to you.

Consider this portable screen when a second display needs to move with your laptop rather than remain on one desk.
The product name specifies FHD. Check that your laptop provides the video connection required by this model and can meet its power needs in the places where you plan to use it.
Check the exact model’s video ports, supported number of external displays and resolution and refresh-rate combinations. Confirm whether the USB-C port you intend to use carries video. Apple Support says Mac display support depends on the model, while Microsoft Support notes that a graphics adapter may limit the number of monitors.
No. USB-C names the connector, not a guaranteed video capability. Match the laptop port to the monitor or adapter’s required display technology; Apple Support specifies compatible DisplayPort Alt Mode or Thunderbolt support, as applicable, for Mac USB-C or Thunderbolt display adapters.
Consider a dock when you want to connect desk accessories, charging and a display through one laptop connection. If you need only one monitor and the laptop already has a compatible video output, a direct connection avoids adding a dock solely for that screen.
Not necessarily. Check the exact laptop and dock combination: Microsoft Support notes that a graphics adapter may support only one monitor, and Apple Support says the supported display count varies by Mac model. For a DisplayLink-based dock, also check its software and operating-system requirements.
Yes. Compare the accessory’s stated host-power output with the laptop maker’s charging requirement and confirm that the intended laptop port accepts charging. A monitor’s advertised output, such as up to 90 W on certain Dell and LG models, does not establish adequate charging for every laptop or workload.
