The MINIX K1 USB-C KVM Switch is built for one specific desk: two computers with full-featured USB-C ports, one HDMI monitor, and one set of USB peripherals. It switches the display, keyboard, mouse, and active charging path together. That makes it simpler than a dock-class KVM, but also much less flexible. This is a research-backed review based on MINIX's published specifications and current product documentation. WorkstationSetup has not tested the K1 hands-on.
Bottom line
Buy it for: Two USB-C laptops sharing one HDMI display, especially when 4K@120Hz support and charging the active laptop matter.
Skip it for: Dual-monitor desks, Apple Studio Display or Pro Display XDR, high-speed external storage, or any computer whose USB-C port cannot carry video.
Main limitation: The three peripheral ports run at USB 2.0 speed, and Power Delivery goes only to the active computer.

How I Evaluated It
This review compares MINIX's official K1 specifications with the requirements of a real two-computer desk. The important questions are not whether the box says 4K or 100W. They are whether both computers can send video over USB-C, whether one monitor is enough, whether USB 2.0 is fast enough for the shared devices, and whether charging only the active computer fits the workflow.
MINIX's documentation is clear about the physical ports, video ceiling, Power Delivery input, conversion loss, dimensions, and included cables. It is less useful on switching behavior. MINIX markets the changeover as instant, while the current retail listing warns that the display can take several seconds to resynchronize. Plan for a brief black screen when changing computers rather than treating the switch as seamless video continuity.
What the MINIX K1 Gets Right
The K1 solves a common home-office problem without turning the desk into a docking project. Each computer connects over one USB-C cable. The monitor connects over HDMI. Keyboard and mouse plug into the front. A compatible USB-C charger connects to the PD input. Pressing the button moves the shared devices to the other computer.
Its 4K@120Hz ceiling is unusual for a compact budget KVM. You only get that mode when the computer's USB-C port carries a sufficient display signal and the HDMI cable and monitor also support 4K@120Hz. If one part of the chain tops out at 4K@60Hz, the KVM cannot create the higher refresh rate. For an ordinary 60Hz office monitor, this extra ceiling is headroom rather than a reason to upgrade the display.
The metal body and small footprint also fit the job. At about 5.3 inches wide and less than an inch thick, it can sit under a monitor shelf or beside a laptop stand without becoming the center of the desk. MINIX includes both USB-C host cables, which removes one common source of USB-C KVM problems. You still need to supply the HDMI cable and charger.
Where the MINIX K1 Falls Short
This is a one-monitor switch. It has one HDMI output and cannot turn a single USB-C display stream into two extended displays. If your workstation needs two monitors, use a dock-class KVM such as the AV Access iDock M10 or start with the USB-C KVM guide for Mac and Windows.
The shared accessory ports are also USB 2.0. That is enough for a keyboard, mouse, basic webcam, headset, or printer. It is a poor path for a fast SSD, high-resolution capture device, or another peripheral that depends on USB 3 speeds. Buyers who see "USB-C 3.2 Gen 2" on the host inputs should not assume the front USB-C port is equally fast.
Charging has two limits. First, the PD input serves the currently active computer, not both computers simultaneously. The inactive laptop needs its own charger if it must remain topped up all day. Second, MINIX rates the input at 100W but lists 5W to 10W of conversion loss. A 100W charger therefore does not mean the laptop receives the full 100W. That is fine for many thin-and-light laptops, but it is not the same as a dedicated high-power charger for a workstation-class machine.
Mac and Windows Compatibility
The K1 can share one monitor between a compatible Mac and Windows computer without a software driver. Both computers need a USB-C or Thunderbolt port that supports video output. A charging-only or data-only USB-C port will not work as the host display connection.
Apple Silicon's display limits still apply, but they are less complicated here because the K1 only has one display output. The bigger Apple limitation is physical: Apple Studio Display and Pro Display XDR do not have HDMI inputs, so they are not direct matches for this switch. Choose a Thunderbolt or USB-C display path designed for those monitors instead.
Desktop PCs require the same caution. A USB-C connector on a motherboard does not automatically carry a display signal from the graphics card. If the desktop's USB-C port does not support DisplayPort Alt Mode or another documented video path, the K1 cannot receive its video over that cable.
MINIX K1 vs the Main Alternatives
Choose the MINIX K1 when the desk has two USB-C computers, one HDMI monitor, and ordinary USB accessories. It is the most direct path when you value a compact body, high-refresh video support, and one charging connection for the active laptop.
Choose the Cable Matters 20Gbps USB-C KVM Switch when the shared device is a compatible USB-C monitor or detachable-cable dock rather than an HDMI display. Its three-computer path fits a different setup than the MINIX.
Choose the AV Access iDock M10 when you need two external displays, more dock ports, and a KVM that replaces more of the workstation's cable infrastructure. It costs more because it solves a larger problem.
Who Should Buy the MINIX K1
- Remote workers switching between a work laptop and personal laptop on one HDMI monitor.
- Mac plus Windows users whose computers both support video over USB-C.
- Buyers with a 120Hz display who want the KVM to preserve that refresh-rate ceiling.
- Desks sharing a keyboard, mouse, webcam, headset, or other USB 2.0-friendly accessories.
- People who are comfortable charging only the active laptop through the switch.
Who Should Skip It
- Anyone building a dual-monitor workstation.
- Apple Studio Display or Pro Display XDR owners.
- Desktop users without a confirmed USB-C video output.
- Anyone who needs USB 3 speed for shared storage, capture hardware, or another high-bandwidth peripheral.
- Two-laptop setups where both computers must charge from the KVM at the same time.
- Buyers who cannot tolerate a brief display resync during switching.
Setup Checklist Before You Buy
- Confirm both computers support video output through the exact USB-C ports you plan to use.
- Confirm the monitor has HDMI input and supports the resolution and refresh rate you want.
- Use an HDMI cable explicitly rated for 4K@120Hz if that is the goal.
- Bring your own USB-C charger. Account for the 5W to 10W conversion loss listed by MINIX.
- Keep high-speed storage connected directly to a computer or a faster dock.
- Keep a second charger available if the inactive laptop must remain charged.
Frequently Asked Questions
Does the MINIX K1 support two monitors?
No. The MINIX K1 has one HDMI output and is a single-monitor KVM. Choose a dual-monitor KVM dock if both computers need to share two extended displays.
Does the MINIX K1 charge both laptops?
No. Power Delivery goes to the active computer. The inactive computer needs its own charger if it must continue charging while the KVM is switched away from it.
Can the MINIX K1 really run 4K at 120Hz?
Yes, as the KVM's published maximum. The computer's USB-C video output, HDMI cable, and monitor must all support 4K@120Hz. The connection falls back to the highest mode supported by the weakest part of that chain.
Are the MINIX K1 USB ports fast enough for an external SSD?
Not for a modern high-speed SSD. The shared USB-C and USB-A accessory ports are USB 2.0, which is better suited to keyboards, mice, headsets, printers, and basic webcams.
Will the MINIX K1 work with a MacBook and a Windows laptop?
Yes, if both machines can send video through their USB-C ports. The K1 does not require a software driver, but it cannot add video support to a port that only carries power or data.
Does the MINIX K1 work with Apple Studio Display?
No, not as a direct connection. The K1 outputs HDMI, while Apple Studio Display and Pro Display XDR do not provide HDMI inputs.
How long is the MINIX K1 warranty?
MINIX publishes a two-year warranty for its products when you have proof of purchase from an authorized retailer. The current Amazon listing text says one year, so confirm that the seller is authorized and keep the invoice if warranty coverage matters to the purchase.
