A KVM is worth considering when both computers need to share a compatible monitor and USB controls, while a standard dock mainly simplifies connections to a compatible laptop. A hub monitor can combine those functions only when that specific model expressly supports KVM; if you only need to change the picture, the monitor’s existing inputs may be enough. Check both computers’ video and USB connections, the laptop’s charging needs and whether any required software is permitted on the work device.
If you regularly move between a work laptop and personal computer, you may want the same screen and controls to follow you. Check both computers’ video and USB connections before choosing a KVM or KVM monitor; ATEN and Plugable describe different approaches to switching in their product information.
If your main aim is fewer connections when you sit down to work, a dock may provide the display and USB ports you need for a compatible laptop. Lenovo’s specifications for its ThinkPad Universal USB-C Dock illustrate why it is important to check compatibility and video output for the particular laptop.
If your monitor already accepts both computers, you may be able to switch the picture without replacing it. Dell distinguishes monitor input selection from USB KVM, so check whether your controls need a separate switching arrangement.
Decide whether the keyboard and mouse must switch with the picture before comparing ports: changing a monitor input and switching USB controls are separate functions.
| Concern | What to check when buying | Who this matters to |
|---|---|---|
| Switching screen and controls together | Check that both computers have the KVM’s required video and USB connections, and that its supported display arrangement matches your monitor. | If I want the keyboard and mouse to follow the picture as I switch computers, I will look for an explicit KVM function; around 33% of consumers put switching the screen and controls together first. |
| Compatibility across both computers and the display | Match the host-video method, monitor inputs and USB connections to both computers; check whether the exact dock requires software. | If I need the same setup to work with two different computers, I will check each connection and any software requirement; around 27% of consumers prioritise avoiding compatibility mismatches. |
| Charging and reconnecting the work laptop | Compare the dock or monitor’s specified power delivery with the laptop’s charging requirement, and check which ports and cables are provided. | If I want to connect the work laptop with fewer steps and keep it charged, I will check its power and connection needs; around 20% of consumers put laptop reconnection first. |
| Keeping useful existing equipment | Check the monitor’s available inputs and whether a separate USB switch is suitable for your computers and peripherals. | If my current monitor still works for both computers, I would rather keep it where practical; around 20% of consumers prioritise using existing equipment. |
A dock that adds ports for one laptop is not automatically a two-computer KVM. You could connect the laptop successfully and still have no way to switch the shared screen and controls to the personal computer.
Map the video and USB connections from each computer to the monitor and peripherals before choosing equipment.
Selecting a different picture input does not necessarily switch the keyboard and mouse. Dell describes input selection as an alternative to KVM on monitors without that function.
If the controls must follow the selected computer, check for an expressly specified KVM function or plan a suitable separate USB arrangement.
Some DisplayLink-powered equipment requires software. Whether that can be installed depends on the particular work device.
Check the exact dock’s software requirements and confirm that the work laptop can use them before relying on that display connection.
A USB-only switch can share peripherals without changing the monitor’s picture. Plugable also specifies that its USB3-SWITCH2 is not compatible with USB-C or Thunderbolt docks.
Check separately how the video signal and USB controls will move between computers.
The CS22H is a reference for a dedicated two-computer HDMI-and-USB KVM arrangement.
The UltraSharp U2724DE illustrates a monitor with a laptop connection, charging and a specified Auto KVM function.
The ThinkPad Universal USB-C Dock 40AY0135UK is an example of a dock for simplifying connections to a compatible laptop.
The USB3-SWITCH2 illustrates a route for sharing USB peripherals when picture selection is handled separately.
These options cover USB-C laptop hubs and monitors for connecting a laptop or selecting between display inputs. The MSI monitor listing also specifies Multi Control for two devices; check each model’s functions and connections rather than assuming all monitors switch both picture and controls.

For adding display and peripheral connections to a compatible USB-C laptop; it is not specified here as a two-computer KVM.
Listed connections include 4K HDMI, VGA, USB 3.0, USB 2.0, Type-C PD, RJ45 Ethernet, SD and TF card readers, and 3.5 mm AUX.

For adding a display and peripheral connections to a compatible device; check that the USB-C connection suits the computer you plan to use.
Listed connections include HDMI 2.0, 2 × USB-A 3.2, 2 × USB-C 3.2 and a PD power input specified at 20 V/5 A. The listed compatibility includes Windows, macOS and Android devices.

For a desk where you want a monitor connection for a laptop and a specified way to control two devices with one keyboard and mouse.
The listing specifies USB-C with 65 W power delivery and a Multi Control function for two devices. It also lists an IPS panel and Dolby Audio.
No image available
For a setup where compatible computers can use the monitor’s different display connections; picture input selection alone does not establish shared keyboard and mouse control.
The listing specifies USB-C, HDMI and DisplayPort connections, QHD resolution and USB-C power delivery up to 96 W. USB hub support is described as varying by region.
Not simply because it is a dock. Lenovo describes the ThinkPad Universal USB-C Dock as a laptop docking solution, while ATEN specifies the CS22H for switching between two computers. Check for an explicit two-host switching function or plan separate connections for the monitor and controls.
Changing a monitor’s input does not necessarily switch its USB controls. Check whether that exact monitor supports KVM and whether both computers have the required USB connections, then follow the monitor’s setup instructions.
For a DisplayLink-connected display, Synaptics recommends checking the video cable and connection path; its initial troubleshooting guidance also covers the host USB port and cable. Check the connections before concluding that the dock itself is faulty.
For covered UK distance sales, GOV.UK says customers can notify the seller that they wish to cancel within 14 days of receiving an item, without giving a reason, and then have another 14 days to return it. Faulty or misdescribed goods have separate remedies. Check the seller’s terms and the circumstances of the purchase; incompatibility alone does not establish that an item is faulty.
It can. The Health and Safety Executive says the guidance can apply to people who routinely split work between home and the workplace and use display screen equipment daily for continuous periods of an hour or more. Where it applies, the employer should assess the individual workstation, including home use; equipment needed as a result of that assessment must not be charged to the worker. This guidance does not require every buyer to choose a particular dock or monitor.
