Start with the video outputs and display limits of both laptops, then choose how to share the screens and peripherals. A USB-C dock is an option when the relevant ports support video; a KVM suits frequent switching when each laptop can drive the intended displays. For an older laptop, a DisplayLink dock may be an alternative if its software is compatible and permitted on the work device.
If both laptops have USB-C ports that support DisplayPort Alt Mode or Thunderbolt, a compatible dock could bring a monitor and USB peripherals together at one connection point. Check each laptop separately: Dell notes that a USB-C port limited to data or charging will not output video.
If one laptop lacks USB-C video output, consider its existing display connections before buying an adapter. A DisplayLink-powered USB dock is another possibility, but DisplayLink software must work on that laptop and be permitted if it is employer-managed.
A KVM can switch supported monitors and USB peripherals between computers. First confirm that each laptop has a suitable path to drive the screens you intend to share; the KVM does not create a missing video output.
Map the connections on both laptops and monitors before deciding whether to consolidate cables with a dock, switch them with a KVM or keep separate display paths.
| Priority | What to check | Your needs |
|---|---|---|
| USB-C video | Check the exact laptop port for DisplayPort Alt Mode or Thunderbolt, then check the dock and cable. Dell says data-only or charging-only USB-C ports do not provide native video. | I would like one connection for a screen and peripherals, but I need to know that each laptop can actually send video through its USB-C port. |
| Display count | Check each laptop’s supported external-monitor count and the required resolution and refresh rate. Match those requirements to the dock or KVM; Microsoft says a display splitter duplicates a signal rather than creating two independent desktops. | Two separate screens matter more to me than simply having two display sockets on an accessory. |
| Switching method | For a KVM, match both laptops’ video paths, the monitor connectors and the USB peripherals you want to switch. With monitors that have multiple inputs, check how you select the active input on each screen. | If I change computers several times a day, I want the keyboard, mouse and screens to follow without reconnecting them individually. |
| Older laptop | Check whether the laptop has a direct video output. For a DisplayLink route, confirm that the exact dock is DisplayLink-powered and that its software supports the operating system. | My personal laptop lacks USB-C video, so I need a connection plan based on the ports it has rather than the shape of a new adapter. |
| Work-device access | Ask your employer or IT team about docks, drivers, webcams and USB switches before connecting them. The UK National Cyber Security Centre advises organisations to assess peripheral risks; Microsoft documents controls that can limit installation to approved devices. | I need the shared desk to work with the restrictions on my work laptop, particularly if a proposed dock needs software. |
| Setup and faults | Check the selected monitor input and test a direct laptop-to-monitor connection if a screen stays blank. Then check the cable, dock path and any applicable software. | I would rather identify which connection has failed before replacing part of the desk setup. |
A USB-C adapter can fit a port yet leave the monitor blank if that port handles only data or charging, as Dell explains.
Find the specification for the exact laptop and port. Confirm DisplayPort Alt Mode or Thunderbolt support, as well as the planned cable and monitor input.
Two display connectors do not establish that a laptop can run two independent external screens. Microsoft notes that a splitter duplicates one signal rather than extending it.
Check each laptop’s external-display limit, then compare its supported resolution and refresh rate with the intended dock, KVM and monitors.
DisplayLink output depends on compatible software. Installation or peripheral controls on an employer-managed laptop may prevent its use.
Confirm that the product is DisplayLink-powered, check operating-system support and ask your employer or IT team whether the software and device are allowed.
A KVM needs suitable connections from both laptops; using separate monitor inputs may instead mean changing the active input on each screen.
Draw out both laptop-to-monitor paths and the connections for the keyboard, mouse and webcam. If switching is occasional, compare that work with using direct cables.
These brands illustrate different connection routes; compatibility depends on the exact product and both laptops, not the brand name alone.
Dell’s USB-C dock information is relevant when checking a laptop’s port capability alongside a dock’s stated display modes.
StarTech.com lists both dedicated dual-monitor KVMs and a two-laptop KVM dock, making the connection layout of the particular model important.
Plugable offers DisplayLink-based docking options, including the UD-3900C, which it describes as connecting to USB-A or USB-C laptops.
These options cover a monitor with several stated connections, USB-C accessories for connecting one laptop at a time, and a monitor with USB-C and HDMI inputs. Check the switching method and both laptops’ video support before choosing one for a two-laptop desk.

For a desk built around one wide screen, check how each laptop would connect and whether the monitor’s switching arrangement covers the peripherals you use. The named variant has a 32:9 aspect ratio, 1800R curve, Double Quad HD resolution and 240Hz refresh rate; confirm the display mode each laptop can drive.

This dock is a connection point to consider for a laptop with compatible USB-C video output; moving between laptops would require changing the host connection. Its name specifies dual HDMI 4K connections and 100W Power Delivery pass-through. Check each laptop’s supported display modes and what power supply your intended setup requires.
No image available
For connecting one compatible laptop to desk accessories at a time, this variant names two HDMI outputs, rated 4K120Hz and 4K60Hz respectively, alongside USB-A, USB-C and RJ45 connections. Check that each intended laptop supports USB-C DisplayPort Alt Mode and the simultaneous display configuration you need; switching laptops means moving the host connection.

If you are adding a monitor rather than switching existing screens, compare this model’s USB-C and HDMI connections with the outputs on both laptops. Confirm how its active input is selected and plan a separate way to share a keyboard, mouse or webcam if needed.
No. For native video through USB-C, the port needs DisplayPort Alt Mode or Thunderbolt support. Dell explains that a data-only or charging-only USB-C port can accept a connector without producing a picture. Check the specification for the exact laptop port.
Check its existing display outputs first. A compatible DisplayLink-powered USB dock or adapter may offer another route through USB data, but it requires suitable DisplayLink software and product-specific operating-system support. On a work laptop, confirm that installation and peripheral use are permitted.
No: Microsoft says a display splitter duplicates the same signal rather than creating two independent desktops. For two extended monitors, confirm the laptop’s supported display count and use an appropriate supported connection arrangement.
Not by itself. A KVM switches existing video and USB connections between computers; each laptop still needs a supported path for the intended screens. Check the laptop’s display limit and the KVM’s required host connections before buying.
Yes, if the work laptop is managed. The UK National Cyber Security Centre advises organisations to assess peripheral access, and Microsoft documents controls that can restrict device installation. Ask your employer or IT team whether the proposed dock, software and peripherals are allowed on your device.
