OVERVIEW
D2H-4P Duo is a dedicated multi-platform KVM switch
capable of managing four 4K computers through a
single, central workstation. Built with ultra-HD ready
HDMI outputs, the D2H-4P Duo offers full video emulation directly from the device. Up until now, DisplayPort switches lost emulated picture when disconnected from monitors, leading to confusion and disorganization upon reconnecting. With the D2H-4P Duo,
full EDID-assisted HDMI video emulation ensures visual workspaces and screen resolutions are remembered every time. The D2H-4P Duo is DisplayPort 1.2
and HDMI compliant, supporting screen resolutions
up to 4K Ultra-HD (3840x2160 @ 30Hz) for remarkable and responsive video emulation. Additionally, the
D2H-4P Duo is USB peripheral-friendly. The D2H-4P
Duo is also easy to control with both a simple frontpanel interface, as well as RS-232 functionality.
