Its main advantage is the straightforward all-HDMI layout. Each source connects through three HDMI cables, making it a natural option for desktops equipped with multiple HDMI outputs. Four USB 3.0 ports can serve a keyboard, mouse, printer, and other peripheral, while the included external controller allows switching when the unit itself sits out of immediate reach.

The trade-off is its more conventional resolution ceiling. It does not offer the 8K capabilities or broad high-refresh-rate combinations found in several mixed DisplayPort and HDMI models. Its switching controls also do not support keyboard hotkeys, and the 4K60 maximum depends on the source device and every cable in the signal path supporting that standard.

Choose this model when you want a two-computer, three-HDMI arrangement without paying for a more advanced dock or 8K switch. It is particularly suitable for productivity desks that need shared peripherals and clean source switching without demanding ultra-high-resolution gaming performance.

A Simpler All-HDMI Layout

Using three HDMI connections for each computer keeps cable planning intuitive. The switch also supports copy mode for duplicating the same visual across all displays, which can be useful for demonstrations or shared-status workstations.

Flexible Switching From the Desk

A front-panel button and included wired extension controller provide two ways to change sources. An indicator light shows the selected computer, reducing uncertainty when both systems remain connected.

Support for HDR, VRR, FreeSync, and G-Sync adds appeal for modern gaming and productivity displays.

Compatibility deserves careful attention. Both computers must support three concurrent displays, and each source needs two DisplayPort connections, one HDMI connection, and a USB link. Signal converters or docking stations can interfere with operation, while the absence of EDID emulation may cause some applications to identify the display arrangement incorrectly.

This is a strong option for a two-computer workstation where one source uses DisplayPort and another uses HDMI. It is especially appropriate for users who want high refresh rates and 8K support but do not need laptop charging, Ethernet, or the broader docking features of the AV Access alternatives.

Resolution and Refresh Flexibility

The mix of DisplayPort 1.4 and HDMI 2.1 makes this switch adaptable to different graphics hardware. Maximum performance still depends on the source, monitor, cables, and operating-system configuration working together.

A Complete Connection Bundle

The extensive cable package is useful for initial setup. Users should still verify that their computers have the required port mix before installation, because a missing connector cannot be replaced by the switch itself.

A single full-featured USB-C cable can carry laptop video, data, and power, helping reduce desk clutter. The desktop connection supports up to 8K60 or 4K165, while the USB-C laptop path supports up to 4K60, 1440p165, or 1080p240. Two USB-A 3.2 ports and one USB-C 3.2 port provide 10Gbps transfer, with three additional 5Gbps USB-A ports for everyday devices.

The central limitation is laptop-platform compatibility. Compatible Windows USB-C laptops can use MST for extended multi-monitor output, but MacBooks are limited to mirrored displays and cannot present independent extended content across multiple external screens. HDMI and DisplayPort cables are also excluded from this version, so appropriate video cables must be provided separately.

Pick the B23 when you want one device to replace a separate dock, KVM, card reader, and possibly some desk adapters. Its integrated charging, active shared Ethernet, and broad USB connectivity make it especially valuable for hybrid workers, developers, traders, and creators who move frequently between a laptop and desktop.

One Cable for the Laptop Workflow

Power, video, and data can travel over a compatible USB-C connection. This is particularly useful when the laptop is the source used most often and the display arrangement changes between docked and undocked use.

Network Stays Connected

The shared 1Gb Ethernet connection remains active on both computers. Background downloads, synchronization, updates, and remote-access tasks can continue on the system that is not currently being controlled.

Users can switch through the panel button or the included wired remote, while the package supplies four USB 3.0 cables, a controller, a manual, and a 12V power adapter.

Every computer must support three concurrent displays, which creates a substantial port requirement. The instructions specifically call for two DisplayPort and one HDMI connection per source, and systems using both integrated graphics and a discrete graphics card may need all three outputs supplied by the discrete card. Shorter, appropriate-quality cables are preferable for stable high-bandwidth signals.

This is the most versatile choice for a multi-PC office that still wants a conventional KVM rather than a laptop-focused dock. It is a good match for administrators or power users who routinely move between several desktop systems and want one keyboard, one mouse, and one monitor group to remain in place.

Four Systems, One Workstation

The four-source capacity removes the need to rearrange cables whenever a different desktop is used. All sources can remain connected, although only the selected computer becomes active with the shared displays and peripherals.

Resolution by Connection Type

The HDMI path can handle 8K60 and 4K120, while DisplayPort supports 8K30 and 4K144. Match the physical output type to the desired resolution and refresh-rate combination on each monitor.

Buying Guide – How to Choose the Best KVM Switch for Triple Monitors

A useful triple-monitor KVM should match your computers' physical outputs, monitor capabilities, and peripheral needs. Review connectivity, resolution, display modes, and source-switching requirements before choosing a model.

Count Your Computers and Displays

Start with the number of systems you need to control. Most triple-monitor KVMs serve two computers, while the options in this guide also include three-computer and four-computer models. A display count alone does not guarantee that every source can drive all three screens, so each computer must independently support three concurrent outputs. A desktop with two DisplayPort and one HDMI connection may need the corresponding port mix on every switch it connects to.

Match DisplayPort and HDMI

Mixed DisplayPort and HDMI designs are versatile because they accommodate different graphics outputs, but they require more careful cable planning. All-HDMI switches are simpler when every source has three HDMI ports, while an all-DisplayPort design can be ideal for high-refresh monitor setups. The physical connector on the computer matters: the switch does not create additional graphics outputs or make an incompatible computer triple-screen capable.

Check Resolution and Refresh Rate

Headline resolution claims are only the starting point. The source graphics card, operating system, monitor, connection type, and cable must all support the desired resolution and refresh rate. Several switches offer 8K60 through HDMI while limiting DisplayPort to 8K30, and some models reach 4K144 or 4K240. For mixed-display workspaces, test the most demanding combination rather than assuming every output can operate at the maximum specification.

Understand Display Modes

Extended mode lets each screen carry different content, making it the normal choice for productivity. Copy or mirror mode repeats the same image across displays and can be useful for presentations, status dashboards, or specialized workflows. A computer that supports only one or two screens will not automatically gain missing outputs through the KVM. Confirm that the operating system and graphics driver permit the intended three-monitor arrangement.

Evaluate USB Connectivity

Look for enough shared USB ports for your keyboard, mouse, printer, webcam, storage, and any other accessories. Four USB 3.0 ports are common in this category, and backward compatibility allows many USB 2.0 devices to work. The USB input from every source must be connected, or shared keyboards and mice may not be recognized. Higher-speed docking models can add 10Gbps ports, card readers, and dedicated charging.

Select the Right Switching Method

A front-panel button is fast and dependable, while a wired remote is better when the switch is mounted under a desk or positioned away from the keyboard. Some products also use indicator lights or keyboard shortcuts, although hotkey support is not universal. Choose a method you can reach comfortably and test it after all displays and peripherals are connected.

Decide Between KVM and Dock

A conventional KVM concentrates on display switching and shared USB devices. A KVM docking station adds features such as USB-C video, laptop charging, Ethernet, audio, and card access. The docking approach is valuable for a hybrid laptop-and-desktop desk, but it introduces laptop compatibility questions. MacBook systems may support mirrored multi-monitor output rather than independent extended screens, so check the exact platform requirements.

Consider Installation Details

A power adapter can improve stability when the switch drives high-power USB devices. Cable length also matters at high resolutions and refresh rates, with shorter cables generally easier to keep stable. Some products include most required cables, while others require separate display connections. Look for a clear indicator of the selected source, and avoid relying on signal converters or docks unless the manufacturer confirms compatibility.

How to Use and Care for Your KVM Switch for Triple Monitors

Before connecting anything, inspect the switch, power adapter, and cables for visible damage. Identify the required inputs for each computer: the relevant DisplayPort and HDMI outputs, a USB host connection for shared peripherals, and the switch's power input. Connect the monitors to the switch's output ports before attaching computer inputs, reducing the chance of confusing source and display cables.

Power on the switch and each computer, then allow the operating system to detect the displays. Open the system's display settings and choose extended mode if separate content is required, or copy mode if the same image should appear on every screen. Arrange the outputs in the desired physical order, select the correct resolution and refresh rate for each monitor, and verify that the image is stable before reconnecting peripherals.

Use the panel button or included wired remote to change the active computer. After switching, allow the operating system to reapply the correct display layout if necessary. Keep the enclosure ventilated, avoid placing it under heavy stacked equipment, and route cables without creating strain on the connectors. If a display fails after a cable or source change, reseat the connection, test the display directly, and use the switch's power control or adapter as directed by its manual.
