Two Laptops, One Desk: The KVM Advantage
Most people who use two laptops at one desk have two sets of monitors, two keyboards, two mice, and two Ethernet cables. Or they unplug everything from one laptop and replug into the other multiple times a day. The KVM dock eliminates both scenarios. Two USB-C host ports connect two laptops permanently. The front toggle button switches all shared peripherals, monitors, and network between them instantly.
The use case is specific and common: a company laptop for work and a personal laptop for everything else. A developer with a Windows machine and a Mac. A consultant who brings their own laptop to a client site that has a different machine on the desk. In each case, the KVM dock keeps one desk setup and switches the entire environment between two machines with one button press. For docks that serve a single laptop, see our docking stations hub page.
90W Active, 45W Standby: Both Laptops Charge
The 180W power adapter feeds both laptops simultaneously. The active laptop receives 90W. The standby laptop receives 45W. When you press the toggle button and switch, the power allocation flips automatically: the newly active laptop gets 90W, the newly standby laptop gets 45W. No manual power management. No charger swapping.
90W charges MacBook Pro (67-96W), most Windows ultrabooks (45-65W), and many workstation laptops at full or near-full speed during active use. 45W on standby maintains the charge on most ultrabooks and slowly charges higher-power machines. Both laptops stay alive throughout the workday.
Dual 4K@60Hz DisplayPort
Two DisplayPort outputs drive two external monitors at 4K@60Hz each. When you switch the active laptop, both monitors switch to showing the new laptop’s display. Your desk has two monitors. Whichever laptop is active uses both screens. The inactive laptop’s screens go dark until you toggle back.
DisplayLink technology enables dual external displays on laptops that natively support only one, including base M-series MacBooks. Driver installation is required on Windows and macOS. The DisplayLink trade-offs apply: no HDCP (streaming services blocked on external monitors), small CPU overhead, and the macOS Screen Recording permission prompt during setup. For USB-C display requirements, see our USB-C portable monitor guide.
Separate Audio and Microphone Jacks
The dock has both a 3.5mm stereo audio output and a separate 3.5mm microphone input. Most docks have a single combo jack. Two separate jacks mean you can connect desktop speakers to the audio out and a dedicated microphone to the mic input without a splitter cable. For video calls, podcasting, or any work that uses separate audio equipment, the dedicated mic jack is a practical detail.
IT Pro Tools and TAA Compliance
Network MAC Address Pass-Through uses the laptop’s MAC address on the wired Ethernet, simplifying corporate network security. WiFi Auto Switching disables WiFi when Ethernet is connected. USB Event Monitoring provides visibility into device connections for IT troubleshooting. These tools matter for IT departments managing multiple docked laptops across an organization.
TAA (Trade Agreements Act) compliance means this dock qualifies for U.S. government procurement. For government agencies and contractors who must source TAA-compliant hardware, the StarTech.com KVM dock meets that requirement.

Frequently Asked Questions
Can both laptops display on the monitors at the same time?
No. Only the active laptop displays on the monitors. The standby laptop’s display goes dark on the external monitors. You toggle between them with the front button. This is how KVM works: one active, one standby.
Does it charge both laptops at the same time?
Yes. The active laptop receives 90W. The standby laptop receives 45W. Both charge simultaneously from the included 180W power adapter.
Will my base M2 MacBook Air get dual monitors through this dock?
Yes, through DisplayLink. Driver installation is required. DisplayLink enables dual displays on MacBooks that Apple limits to one external screen. HDCP content (Netflix, Disney+) will not play on the external monitors.
Why DisplayPort and not HDMI?
StarTech.com chose DisplayPort 1.4 for 4K@60Hz dual output. If your monitors have HDMI only, you need a DisplayPort-to-HDMI adapter (not included). Most professional monitors have DisplayPort inputs.

Docking Station Intelligence
The standards are confusing by design. These three panels decode what manufacturers won’t explain clearly. Applicable to every docking station.
The USB-C Confusion Matrix
The USB-C connector is the single greatest source of buyer confusion in docking stations. The physical plug looks identical whether it carries USB 2.0 at 480 Mbps or Thunderbolt 5 at 120 Gbps — a 250x difference in capability hidden behind the same shape. Manufacturers exploit this by labeling everything "USB-C compatible" without specifying which protocol runs through it. Two docks can look identical on the outside and behave completely differently once you plug them in.
The hierarchy matters because it determines everything: how many monitors your dock can drive, how fast files transfer, whether your laptop charges while docked, and whether you need third-party drivers. Here is the real capability ladder, from slowest to fastest:
The practical takeaway: if your laptop has Thunderbolt 4, buy a Thunderbolt dock. If it only has generic USB-C, verify whether it supports DisplayPort Alt Mode before buying anything with multi-monitor claims. Our buying guide walks through verification steps for every major laptop brand.
Power Delivery: What the Watts Mean
Power Delivery (PD) determines whether your docking station can charge your laptop while you work, or whether you need a separate charger cluttering your desk. The math is simple but rarely explained: your laptop draws a specific wattage under load, and the dock must match or exceed it. If the dock delivers less than your laptop needs, the battery slowly drains even while plugged in — defeating the purpose of a docking station entirely.
Most ultrabooks need 45–65W. Standard business laptops need 65–100W. Gaming and workstation laptops can demand 100–140W or more. The dock’s advertised PD wattage is the maximum it can deliver to your laptop — but this drops if you charge other devices (phones, tablets) through the dock simultaneously. Always leave a 15–20W margin above your laptop’s requirement.
Check your laptop’s original charger wattage — that’s your baseline. Our FAQ covers how to find this for every major brand.
Native Display vs DisplayLink: The Hidden Factor
This is the decision most buyers don’t know they’re making. When a docking station outputs video to your monitors, it uses one of two fundamentally different methods: native (the dock passes your laptop’s GPU signal directly to the monitor) or DisplayLink (the dock compresses video over USB and a software driver renders it). The difference is invisible in marketing materials but profoundly affects your daily experience.
Native output through DisplayPort Alt Mode or Thunderbolt uses your laptop’s actual graphics hardware. There is zero added latency, full DRM support for streaming services, no CPU overhead, and no driver to install. DisplayLink, by contrast, adds 5–15ms of latency (noticeable in video calls and cursor movement), blocks DRM content on connected monitors (Netflix, Disney+ show black screens), consumes 3–8% of your CPU constantly, and requires a driver that Apple’s macOS security updates occasionally break.
DisplayLink exists for one reason: Apple Silicon base chips (M1, M2, M3) can only drive one external display natively. If you need two or more monitors on a base MacBook Air or 13” MacBook Pro, DisplayLink is your only option. For everyone else — Windows users, Mac Pro/Max chip users, Intel/AMD laptops — native is always the better choice.
Native (Alt Mode / Thunderbolt)
DisplayLink (USB compression)
The bottom line: if your laptop supports native multi-display output, always choose a native dock. DisplayLink is a workaround, not an upgrade. See our glossary for detailed definitions.
