MZTC344H: the HDMI KVM Switch That Lets Two PCs Share Everything
The MZTC344H is a 4K 60Hz HDMI KVM switch: two computers share one monitor, keyboard, mouse and printer, switched by a single button with no recabling.
The most efficient desk accessory is the one that deletes work, and the MZTC344H deletes a category of it: the crawling, the swapping and the negotiating that happen whenever two computers must share one set of equipment. Per the official product page, it is a 4K at 60Hz HDMI KVM switch with two HDMI inputs and one output, which lets two computers share a single monitor, keyboard, mouse and printer, changing between them with seamless one-button switching.
The Full KVM: Display and Peripherals Together
The K in KVM stands for keyboard and video together, and that togetherness is the point. Display-only switches move the screen and leave you reaching for a separate peripheral solution; peripheral-only switches leave the monitor swap to the cables. The MZTC344H does both in one button press: the display and the shared USB devices follow each other to whichever computer you choose, with the shared peripherals running over USB 2.0 at 480Mbps, bandwidth that keyboards, mice and printers use only a fraction of.
Why One Button Beats Cable Swapping
The argument for a KVM switch is reliability as much as convenience. Every swap ritual is a plug-in cycle on connectors that were never designed for daily wear, and worn connections are where the intermittent display faults and phantom disconnections begin. A switch installs the cables once, seats them fully, and moves the signal electronically instead. Fewer cycles, longer connector life, and a desk that stays tidy behind the monitor, which is where the MZTC344H lives its whole life anyway.
4K 60Hz Without Compromise
The video specification is the other half of the promise: 4K at 60Hz through both inputs, so neither computer gets a downgraded picture on its days with the screen. For shared workstations, design-review desks and finance setups where two machines alternate on one calibrated display, that symmetry is what makes the arrangement feel native rather than compromised.
The Switch Family, Complete
The MZTC344H completes a switching family in the Mattzon KVM line: the MZTC344D switches DisplayPort at up to 8K 60Hz for display-focused setups, the MZTC344A shares USB peripherals across two computers, and the 344H joins display and peripherals in the full KVM arrangement. All three ship from our Shenzhen factory with per-port testing and aging screening on every unit, under the standard Mattzon terms: 89% private-mold products, OEM and ODM service welcome, no minimum order quantity and 3 to 25 day lead times.
