Why Choose HKS403-P24
Overview
01
Four PCs Across Three Displays
Bring up to four HDMI computers onto one triple-monitor workstation and control them with one keyboard and mouse. The layout is built for users who need more simultaneous information without duplicating peripherals.
02
Three Displays, More Flexible Modes
Use all three displays with one selected computer, or route different computers to individual monitors for monitoring and comparison. Keyboard and mouse focus can follow the system you need to control.
03
EDID Keeps Display Layouts Stable
Built-in EDID emulation keeps display information available to each input so switching is less likely to trigger resolution changes, missing displays or rearranged windows.
04
Triple 4K60 Capability
The KVM supports up to 3840×2160@60Hz 4:4:4 and is backward compatible with lower resolutions and higher refresh-rate combinations supported by the connected hardware.
05
Keep USB and Audio on the Computer You Choose
USB and audio focus can be locked to a chosen computer instead of always following the display selection, useful when a headset, storage device or meeting needs to stay active on one system.
06
One Peripheral Set for Four Systems
Share USB 3.0 devices, a keyboard, mouse and 3.5mm audio/microphone across the workstation instead of connecting duplicate accessories to every computer.
07
Switch Without Reaching for Cables
Use the front panel, IR remote, keyboard hotkeys or mouse-wheel switching to move between computers without unplugging devices.
