Choose a KVM switch if you want the monitors, keyboard and mouse to change computers together. A USB switch with each computer connected directly to the monitors keeps video switching separate, which may suit a gaming display mode that a particular KVM cannot support. A dock simplifies connecting the laptop, but does not by itself switch the gaming PC into the same setup; check both computers’ display connections, shared USB devices and laptop charging needs before buying.
If the same monitors, keyboard and mouse need to follow whichever computer is active, a KVM is worth considering. Which? describes a work-laptop and gaming-PC desk sharing dual monitors and peripherals; the KVM still has to match your own connections.
If a particular gaming display mode or two independent screens matter most, check the entire video path before putting a KVM between the PC and monitors. ATEN documents different single- and dual-display KVM designs, while Microsoft notes that a splitter duplicates a signal rather than creating independent displays.
If the work laptop is frequently removed from the desk, a dock can make its display, peripheral and charging connections more convenient. Dell cautions that not every USB-C port carries video, so the laptop and dock must be checked together.
Decide whether the monitors must switch with the peripherals, or whether changing monitor inputs separately is acceptable. Then check the laptop port and the display mode required by each computer.
| Concern | What to check | Who this matters to |
|---|---|---|
| Whole-desk switching | Count the monitors that must follow the active computer; match both hosts’ video and USB connections to the KVM. | If reconnecting the keyboard, mouse and monitors interrupts the change from work to gaming, switching them together is the main need. About 31% of consumers put whole-desk switching first. |
| Gaming display mode | Check each monitor’s required resolution, refresh rate and inputs against the complete PC-to-monitor path, including any KVM. | For a desk built around a particular gaming display mode or independent screens, retaining that arrangement takes priority over one-button switching. Keeping the gaming display configuration is the primary need for about 31% of consumers. |
| Laptop connection and charging | Confirm video-capable USB-C or Thunderbolt, supported display count and the power the laptop can receive through the chosen dock. | When the work laptop leaves the desk regularly, reconnecting displays and peripherals through one cable matters most. About 23% of consumers primarily want that simpler laptop connection and suitable charging. |
| A simpler setup | Check whether the monitors already have suitable inputs for both computers and which USB devices actually need sharing. | If changing monitor inputs manually is acceptable, sharing just the necessary peripherals may avoid adding a video switch. Keeping additional hardware to a minimum comes first for about 15% of consumers. |
A USB-C dock or KVM can fit the laptop’s port yet fail to provide monitor output. Dell states that not every USB-C port supports video.
Check the laptop manufacturer’s documentation for DisplayPort Alt Mode or Thunderbolt support before choosing a video-capable dock or KVM.
A single-display switch does not establish support for two independent extended displays. Microsoft also distinguishes a splitter’s duplicated signal from independent outputs.
Check the intended display count against both computers’ graphics capabilities and the exact KVM’s host and monitor connections.
Charging through a dock or KVM depends on the device, its power supply, the connection and the laptop’s requirements.
Compare the laptop’s charging requirement with the selected model’s pass-through specification and required power supply.
A KVM specified for 4K at 60 Hz does not, on that specification alone, establish support for a higher refresh rate or another desired display feature.
Match the exact video mode and connectors across the PC, switch and monitor. If the required mode cannot be confirmed, consider keeping the gaming PC directly connected to the monitor.
Relevant when a laptop and desktop need a specifically matched hybrid KVM connection.
Relevant for dedicated KVM layouts where the computers’ video connections match the chosen switch.
Relevant when the priority is connecting the work laptop through a dock.
Relevant when both computers need a dual-monitor KVM and the specified host connections fit the desk.
This docking station is relevant if connecting the work laptop to two displays and providing power pass-through is the priority. Sharing those displays or peripherals with the gaming PC requires a separate switching arrangement.

Consider this dock for the laptop side of a two-monitor desk, rather than as a switch between the laptop and gaming PC.
Its listed configuration includes dual HDMI 4K connections and 100W Power Delivery pass-through. Before buying, confirm the laptop’s USB-C video and charging compatibility, the intended display modes and how the gaming PC will connect to the monitors and shared peripherals.
It can if its connection supports the video method required by the dock or KVM. Dell notes that not every USB-C port provides video output; check the laptop’s documentation for DisplayPort Alt Mode or Thunderbolt and confirm the selected device’s requirements.
A basic splitter duplicates the same signal rather than creating two independent displays, according to Microsoft. For an extended two-monitor workspace, check support across the laptop’s graphics hardware and the proposed dock or KVM connection.
Only if the particular KVM provides suitable laptop power delivery; switching video and USB does not establish charging support. Compare its power specification and supply requirements with the laptop’s charging needs, or plan to use the laptop charger separately.
Identify the exact model, supplied power equipment and safety instructions, as well as the connections your desk needs. GOV.UK provides guidance on UKCA or CE marking for products placed on the Great Britain market; the applicable requirements depend on the product, so do not treat a listing’s marking alone as a compatibility check.
