KVM Switch 2 Monitors 2 Computers HDMI KVM Switches 8K@60Hz - Dual

In this review of the KVM Switch 2 Monitors 2 Computers from Closs, the bottom line is simple: this unit is for users who need to control two computers with one keyboard and mouse while sharing two HDMI displays. The biggest reason to buy is the dual-monitor capability at high resolutions - it supports up to 8K@60Hz when the host systems, monitors and cables all support that bandwidth, letting designers, video editors and power users switch work and personal rigs without losing desktop space. Setup requires two HDMI outputs per PC and your own HDMI cables, so expect a bit of cable work up front.

Key Features

• Dual monitor KVM: Lets a single keyboard and mouse control two separate computers while sharing two HDMI monitors for extended or mirrored desktop setups.
• 8K visual support: Handles resolutions up to 7680x4320@60Hz and is backward compatible with common 4K and 1080p modes for detailed, stable images.
• USB 3.0 ports: Four USB 3.0 ports provide up to 5Gbps for sharing printers, storage and peripherals between both computers.
• Desktop controller switching: Switch between systems using the included desktop controller or the device button for quick, visible selection with LED indicators.
• Extended and copy modes: Supports extended desktop and copy (mirrored) mode when the connected hosts support dual display output.

Who It's For

The KVM is aimed at professionals and power users who run two full desktop systems and need both displays available without duplicating input devices, such as content creators who edit on one machine and render on another or developers who test on separate OS installs. The unit is also useful for home office users who keep a work PC and a personal PC on the same desk.

It is not for casual users with single-output GPUs or laptops without dual HDMI outputs, nor for setups that rely on DP-to-HDMI or HDMI-to-DVI adapters, since the switch requires two native HDMI outputs per computer and does not support those adapters.

Pros & Cons

Pros

• Supports very high resolutions up to 8K@60Hz for detailed, high-fidelity display when all components are compatible.
• Four USB 3.0 ports enable fast sharing of storage and peripherals across two computers.
• Desktop controller provides fast, physical switching and a tidier desktop when hidden under a desk.
• Plug-and-play compatibility across common OSes simplifies installation for most users.

Cons

• Requires two HDMI outputs on each computer and six HDMI cables in total, increasing cable complexity and cost.
• No keyboard hotkey switching; switching is physical only, which may slow workflows for some users.

Specifications

Our Verdict

The Closs dual-monitor HDMI KVM switch is a practical choice for users who need full dual-display control across two desktops and want high-resolution output up to 8K when the rest of their hardware supports it. It delivers strong value through USB 3.0 peripheral sharing and a convenient desktop controller, but buyers should be prepared for the required HDMI cable count and the lack of hotkey switching.

Frequently Asked Questions

Do I need extra HDMI cables?
Yes. Each computer requires two HDMI cables and the package does not include HDMI video cables, so users must supply six HDMI cables in total for a full setup.

Will 8K work with any monitor?
8K@60Hz output depends on the monitor, HDMI cables and computer GPU supporting that resolution; otherwise the switch will fall back to lower supported resolutions.

Are keyboard hotkeys supported?
No. This model does not support hotkey toggles; switching is done via the desktop controller or the button on the unit.
