For laptop work mainly at one desk, consider a desktop monitor you can position comfortably alongside a separate keyboard and mouse; if the second screen needs to travel, consider a portable monitor instead. Add a dock only after checking your exact laptop’s video-capable ports, supported external-display count and charging requirements. For an employer-managed laptop, check equipment and peripheral-approval arrangements before buying.
Where you work and how many connections you need matter more than choosing the largest screen or the dock with the most sockets.
If documents, messages and calls regularly compete for laptop screen space, a separate display can give them distinct viewing areas. For prolonged laptop use, the Health and Safety Executive advises using a separate keyboard and mouse so the laptop screen can be raised, or using a separate display.
A portable monitor is worth considering when you need another display at more than one location. Check the monitor’s stated USB-C video and power requirements against your laptop before assuming it will work with one cable.
A dock can bring display and peripheral connections together, but its usable external-display count depends on the exact laptop and connection mode. Apple’s Mac guidance and Kensington’s SD5760T specifications both show why the laptop’s own display support needs checking.
Decide where the screen will be used, then check the laptop connection and the position of the whole workstation before adding a dock or accessories.
| Priority | What to check | Your needs |
|---|---|---|
| Screen location | Decide whether a full-size display can stay at one desk or the second screen must travel. Check its size and how you will position it in each location. | I keep documents and messages open together, but my choice depends on whether I work mostly at a fixed desk or carry the extra screen between locations. |
| Video compatibility | Check the exact laptop model, port specifications and the display’s required input. For a USB-C video connection, confirm the stated DisplayPort Alt Mode or Thunderbolt requirements; the connector shape alone is not enough. | I want the additional screen to connect to my existing laptop, not just a cable that fits its socket. |
| Multiple displays and power | Confirm the laptop’s supported external-display count, the dock’s operating-system and chipset conditions, and the charging power required by the laptop. Kensington specifies just one external display with its SD5760T for M1/M2 base-chip MacBooks and USB-C Alt Mode laptops. | With several screens and desk devices, I need to know which displays can extend my desktop and whether the connection meets my laptop’s charging needs. |
| Workstation position | Plan screen height and desk space alongside keyboard and mouse position. For prolonged laptop use, the Health and Safety Executive advises a separate keyboard and mouse with a raised laptop screen, or a separate display. | A second screen is useful, but I also need a workable position for typing and viewing during longer sessions. |
| Employer arrangements | Ask about your employer’s workstation assessment, supplied equipment and approval rules before connecting personally purchased peripherals to a managed laptop. | Before I buy a dock or monitor for work, I want to know what equipment my employer will provide and which connections its IT team permits. |
A matching plug does not establish that the laptop provides the video mode a monitor, dock or adapter requires. Apple and StarTech.com specify particular host and adapter capabilities for their documented connection routes.
Check the exact laptop’s video-output specification against the display or adapter’s stated DisplayPort Alt Mode or Thunderbolt requirements before choosing a cable.
Two video outputs do not guarantee two extended displays with every laptop. Kensington states that its SD5760T supports only one external display with M1/M2 base-chip MacBooks and USB-C Alt Mode laptops.
Match the dock’s compatibility information to your laptop model, chipset, operating system and connection mode, then confirm the supported display arrangement.
A second display alone does not change the position of a laptop keyboard. The Health and Safety Executive advises a separate keyboard and mouse for prolonged laptop use so the laptop screen can be raised, or a separate display can be used.
Plan the screen position, separate input devices and available desk space together; use your employer’s workstation-assessment process where it applies.
In Great Britain, the Health and Safety Executive says workers cannot be charged where a display-screen-equipment workstation assessment indicates action such as providing equipment. Approval to connect a personal peripheral is a separate employer decision.
Ask about the assessment, supplied equipment and IT approval route before purchasing or connecting a monitor, dock or adapter for an employer-managed laptop.
These examples illustrate different display and connection routes; check the specification of the particular model you are considering.
Dell’s UltraSharp range includes desktop monitors for a fixed workspace.
Lenovo’s ThinkVision portable displays are relevant when a second screen needs to move between workplaces.
Kensington’s SD5760T is a dock option for bringing compatible desk connections together.
StarTech.com’s display adapters offer a route to examine when a laptop needs additional display connections rather than a full desk dock.
These options cover a fixed desktop monitor, portable second screens and USB-C desk-connection hardware. Choose the route that matches where you work, then check the exact laptop connection and display support.

For a desk where two HDMI display connections and laptop charging are priorities. The named configuration has dual HDMI 4K outputs and 100 W Power Delivery pass-through; check whether your laptop supports the intended extended-display setup and whether the required external power adapter is included.
No image available
Consider this FHD portable screen when the second display must travel with your laptop. Confirm that your exact laptop supports the monitor’s required USB-C DisplayPort Alt Mode connection.
No image available
For a movable second screen where touch input matters. The product name specifies 100% sRGB, VESA compatibility and a 180° adjustable stand; check your laptop’s USB-C video and power requirements, and check the monitor’s weight if you will carry it regularly.
No image available
For connecting displays and wired desk devices through a USB-C hub. The named configuration has two HDMI outputs, listed individually at 4K 120 Hz and 4K 60 Hz, alongside USB, RJ45, SD/TF and USB-C PD connections. Check your laptop’s USB-C video support and the hub’s simultaneous display modes rather than assuming both listed HDMI modes work together.

For a second display that can remain at a fixed desk. Check that your laptop has a compatible display output, which cable comes with the monitor and whether its stand offers the positioning adjustment you need.
No: the USB-C connector shape does not guarantee video output. Check your laptop’s exact port specification against the monitor or adapter’s DisplayPort Alt Mode or Thunderbolt requirements; Apple and StarTech.com both specify connection capabilities for their documented products.
Do not assume it can. Apple advises checking a Mac model’s supported displays, while Kensington states that its SD5760T provides only one external display with M1/M2 base-chip MacBooks and USB-C Alt Mode laptops. Check the laptop and dock together for the display arrangement you want.
Choose by where the second screen will be used: a desktop monitor suits a screen that can stay at one desk, while a portable monitor suits one you must carry. For either route, check the laptop connection and plan the screen position with your keyboard and mouse; a portable display alone does not arrange the rest of the workstation.
There is no automatic entitlement to every accessory. In Great Britain, the Health and Safety Executive says workers cannot be charged when their display-screen-equipment workstation assessment indicates action such as providing equipment. Ask your employer about the assessment and which equipment it calls for.
Check your employer’s IT and equipment rules before connecting it. Approval for a personal dock or adapter depends on that employer’s arrangements; also confirm the dock’s video, display-count and charging compatibility with the exact laptop.
