Four-Port HDMI KVM Switch for Four Computers
This IHDAPP 8401BA KVM switch connects four desktops or laptops to a single HDMI monitor. One keyboard and mouse control all four systems through the four USB 3.0 ports, eliminating the need for multiple peripherals. The unit includes a wired remote and front push buttons for source selection, plus a 3.5 mm audio output for headphones or speakers.
Sustained 8K and 4K Video with EDID Emulation
The switch maintains stable video at up to 8K resolution at 60 Hz and 4K at 120 Hz during continuous operation. An integrated EDID emulator preserves display handshake data so resolution and refresh rate remain consistent when switching between computers. USB 3.0 ports sustain 5 Gbps data throughput for attached storage or peripherals without throttling. The included 12 V DC power adapter ensures reliable performance under full four-port load.
Verify 8K HDMI 2.1 Cables and Host Compatibility
Before ordering, confirm that each computer and the monitor support 8K at 60 Hz or 4K at 144 Hz over HDMI 2.1. You must supply 8K-rated HDMI 2.1 cables for every connection; the package includes only one HDMI cable. The switch requires a free USB 3.0 port on each host for peripheral sharing and the 12 V DC input for power.

Questions about this item
Does the 12 V DC adapter make the switch run hot or noisy during all-day use?
The unit draws power from the included 12 V DC adapter and has no internal fan, so it operates silently and stays cool even with four computers connected continuously.
Which cables and peripherals must I already own to connect four PCs to one monitor?
You need four HDMI 2.1 cables for 8K@60 Hz video, four USB 3.0 cables for keyboard, mouse and other 5 Gbps devices, plus a single HDMI 2.1 cable from the switch to the monitor.
Will my older 4K@60 Hz monitor and USB 2.0 keyboard work reliably through the 8K@60 Hz switch?
Yes, the EDID emulator presents a stable 8K@60 Hz profile to every PC while down-scaling to your monitor’s native timing, and USB 2.0 peripherals negotiate at 480 Mbps on the 3.0 ports without extra setup.
