IHDAPP USB 3.0 Dual Monitor HDMI KVM Switch 4 PC 2 Port 4K 60Hz

Four-PC dual-monitor KVM switch

This IHDAPP KVM switch lets one keyboard, mouse and two HDMI monitors control four computers or laptops. It includes EDID emulation on every input so each PC keeps the correct display settings when switching. Three USB 3.0 ports share peripherals such as flash drives or wireless dongles across all connected systems. A wired remote and front-panel buttons both change the active computer with LED indication.

HDMI 2.0 bandwidth and EDID limits

The switch conforms to the HDMI 2.0 protocol, capping video at 4K 60 Hz YUV 4:4:4 with HDCP 1.4 and HDR 2.2 support. Each source must provide two HDMI outputs to feed both monitor ports; single-output devices cannot drive the dual-display modes. USB 3.0 peripheral bandwidth reaches 5 Gbps and falls back to USB 2.0 or 1.1 for older devices. No external power supply is required for the KVM itself.

Four-computer simultaneous switching

The decisive specification is the ability to switch four independent PCs across two monitors while preserving EDID data on every port. Buyers who need to manage more than four systems or who only have single-HDMI outputs on their sources will find this unit unsuitable. Extended, mirrored or spliced dual-monitor layouts depend on each computer's own graphics capability.
