Dual-PC Triple-Monitor KVM Switch

This DisplayPort KVM switch connects two computers to three monitors and four USB 3.0 ports. A single keyboard and mouse control both systems with support for duplicate and extend display modes. The unit handles resolutions up to 8K at 60 Hz and 4K at 120 Hz. It ships with a wired remote controller and a 12 V power adapter for stable operation.

Installation Requirements and Common Issues

Each computer must provide three DisplayPort outputs and one USB 3.0 port, requiring twelve DP cables and two USB cables in total. The switch draws power from the included 12 V 1 A adapter, so a free mains socket is necessary. Problems usually arise when a graphics card lacks three DP ports or does not support multi-stream transport for extend mode.

DisplayPort Bandwidth and USB Limits

The 8K 60 Hz and 4K 120 Hz capabilities depend on the host GPU’s DisplayPort link rate and DSC support, which the switch does not control. USB 3.0 ports operate at 5 Gbps and remain backward compatible with USB 2.0 and 1.1 devices. High-power peripherals may exceed the adapter’s current budget if several are used simultaneously.

Questions about this item

How can I verify the IHDAPP KVM switch is working correctly after connecting two PCs and three monitors?

Check the LED indicators on the unit to confirm the active PC port, then verify all three monitors display an image at up to 8K@60Hz or 4K@120Hz and test keyboard, mouse, and USB 3.0 device response on both computers.

What cables and accessories are included in the box, and what must I provide separately?

The box contains the KVM switch, two USB 3.0 cables, a wired desktop controller, a 12V power adapter, and a user manual; you must supply six DisplayPort cables (three per computer) for the video connections.

Which display mode should I choose between duplicate and extend for my three-monitor setup?

Choose duplicate mode to show identical content on all three screens, or extend mode to spread the desktop across them for multitasking; both require your graphics card to support three DisplayPort outputs.
