Choose a multi-input monitor if you only need to change which laptop appears on screen and can keep separate controls. If one keyboard and mouse must follow the selected laptop, check for a built-in or standalone KVM switch; a dual-host KVM dock also needs compatible laptop video connections and adequate power delivery. Check both laptops’ ports, display capabilities and any employer restrictions before buying.
If you alternate between a work laptop and a personal laptop, decide whether you want to switch the screen alone or move the keyboard and mouse between computers too. That distinction determines whether monitor inputs are enough or you need a KVM function.
A multi-input monitor can show either laptop while you continue using each laptop’s own keyboard and trackpad, or keep separate peripherals. You do not need shared USB control simply to select a video input.
A connection that works with your personal laptop may still require approval on a managed work device. The UK National Cyber Security Centre identifies device management and security risk as considerations in bring-your-own-device and home-working arrangements; check your organisation’s rules before choosing shared USB equipment or driver-dependent hardware.
Start with what must switch between laptops, then check whether each laptop can make the required video, USB and charging connections.
| Priority | What to check | Your needs |
|---|---|---|
| Display switching | Check that the monitor has an input for each laptop and that both laptops can output the display mode you intend to use. Multiple inputs select the picture; they do not, by themselves, switch USB peripherals. | I only need to change which laptop is on screen. I can use each laptop’s own keyboard and trackpad, or keep separate peripherals. |
| Shared controls | Look for a documented built-in KVM or a standalone switch with connections for your monitor and both computers. Dell specifies shared keyboard-and-mouse control for its U3824DW monitor; StarTech.com specifies it for its cited two-computer KVM. Check the exact model rather than assuming the feature is standard. | One keyboard and mouse should control whichever laptop I select, without moving their connections by hand. |
| Dock video compatibility | Identify the capabilities of the specific USB-C port on each laptop, not just its shape. Lenovo says its cited docks require USB-C Alt Mode or Thunderbolt support; StarTech.com lists different display configurations for its cited dock depending on DisplayPort and DSC capability. | I want a dock to carry the display connection, but need to know that both laptops support the required monitor configuration. |
| Laptop charging | Compare each laptop’s charger requirement with the power delivered in the intended setup. StarTech.com states up to 90W for the active host and 45W for the standby host on its cited dual-host dock. Lenovo states that its cited travel dock reaches up to 100W with an additional 135W USB-C adapter. | Fewer charging cables would help, provided the dock’s stated output is adequate for the laptop it will charge. |
| Work-device approval | Check whether your employer permits the intended dock, required drivers and shared USB devices. Approval is separate from whether the ports are technically compatible. | My work laptop is managed, so I need a switching arrangement I am allowed to connect and use. |
A cable may fit while the laptop cannot provide the display mode the dock requires. Lenovo specifies USB-C Alt Mode or Thunderbolt compatibility for its cited docks, and StarTech.com distinguishes between DisplayPort capabilities for its cited dock’s display configurations.
Find the exact laptop model and host-port specifications, then compare them with the dock’s compatibility and display-mode information for the monitors you plan to connect.
Power can differ between active and standby hosts. StarTech.com specifies up to 90W and 45W respectively for its cited dual-host KVM dock; Lenovo’s cited travel dock requires an additional 135W adapter to provide up to 100W to a laptop.
Check the power allocation in the connection state you will use and compare it with each laptop’s charging requirement.
Selecting a different monitor input changes the displayed computer, but shared controls require an explicitly documented KVM feature or separate switching hardware.
If the same keyboard and mouse must follow the picture, confirm how the chosen monitor or KVM connects to both laptops for USB control as well as video.
A driver-dependent dock or shared USB arrangement may not fit an employer’s device-management rules, even when the physical connections match. The UK National Cyber Security Centre treats device management and security risk as organisational considerations.
Check with your employer before installing required software or attaching personal peripherals and USB devices to the work laptop.
These examples illustrate features to check on specific models, rather than features shared by every product from a brand.
Dell’s U3824DW UltraSharp monitor is an example of a monitor-led setup with a stated built-in KVM.
StarTech.com documents both standalone two-computer KVM switches and dual-host USB-C KVM docks.
Lenovo’s dock documentation is useful when checking USB-C Alt Mode or Thunderbolt compatibility, including for a ThinkPad setup.
This monitor option addresses a desk where two devices may share keyboard-and-mouse control. Confirm how both laptops must connect before relying on it as your complete switching setup.

The listing describes Multi Control for using one keyboard and mouse across two connected devices, a relevant feature if both laptops need shared controls. It also states USB-C power delivery up to 65W. Check the video and USB connections required for each laptop to use Multi Control, and whether 65W meets the charging needs of the laptop you intend to connect by USB-C.
Check both laptops’ exact host ports, supported external-display configurations and charging requirements, along with any driver requirements. A USB-C socket alone does not establish video support: Lenovo specifies USB-C Alt Mode or Thunderbolt for its cited docks, while StarTech.com lists display modes that depend on DisplayPort and DSC capability for its cited dock.
A multi-input monitor is enough if you only need to choose which laptop appears on screen and can use separate controls. If one keyboard and mouse must control the selected laptop, check for an explicit built-in KVM, as Dell specifies for its U3824DW, or use a separate KVM with the connections your setup requires.
A dual-host dock can provide power to both, but the allocation depends on the model and which host is active. StarTech.com states up to 90W for the active laptop and 45W for the standby laptop on its cited dock. Compare each allocation with the relevant laptop’s charging requirement before planning to remove either charger.
Check your employer’s rules before connecting them, particularly if the dock needs software or the KVM shares USB devices. The UK National Cyber Security Centre identifies device management, usability and security risk as organisational considerations; hardware compatibility does not establish employer approval.
