3-Computer 2-Monitor KVM Switch
The IHDAPP SW520 lets one keyboard, mouse and dual-monitor setup control three separate computers. It is aimed at users who need to operate multiple workstations or a mix of desktops and laptops from a single desk. The unit also shares four USB 3.0 peripherals across all connected hosts.
HDMI 2.0 Connectivity and EDID Simulation
Each computer connects through an HDMI 2.0 port and a USB 3.0 cable, while the two monitors attach to the switch’s HDMI outputs. EDID simulation keeps window layouts intact when switching between machines. Front-panel push buttons and an included IR remote provide two ways to change the active system without reaching behind the unit.
4K@60Hz Limit and Dual-GPU Requirement
The switch passes video up to 4K at 60 Hz and falls back to 4K@30Hz, 1440p@60Hz or 1080p@60Hz when sources or cables cannot sustain the top rate. Dual-monitor extended mode only works if each computer supplies two HDMI outputs; single-GPU systems cannot drive both screens independently. Hot-key switching is not supported.

Questions about this item
Does the HDMI 2.0 interface on this SW520 limit dual-monitor output to 4K at 60 Hz?
Yes, the HDMI 2.0 ports cap each display at 4K@60Hz, with backward compatibility for 4K@30Hz, 1440P@60Hz and 1080P@60Hz.
What cables and ports are required on each computer for the dual-monitor setup?
Each computer needs two HDMI ports and one USB-A port; the box includes three USB 3.0 cables for those connections.
How do you switch between the three connected PCs, and what common mistake should be avoided?
Use the front-panel button or the IR remote; the mistake is forgetting to plug the USB 3.0 cable into every PC, which leaves shared peripherals unrecognised.
