Introduction
IOGEAR’s 4Kx2K 4-Port HD Switch allows users to connect up to four HD
source devices to one HD display and supports Ultra HD 4Kx2K, the latest
digital format for high-denition displays at a distance of up to 50ft. For easy
access and convenience, this switch has one HD port on the front panel
that can be used to connect your portable devices, such as laptops, tablets
or digital cameras, while the other three HD ports on the back provide
permanent connections for your Blu-ray players, set-top boxes, game
consoles and more.
Switching between source devices can be done via the front panel push-
buttons, RS-232 bi-directional control or IR remote control with front panel
LEDs indicators for each source device. The built-in bi-directional RS-232
serial port allows you to control the switch through a high-end controller, PC
and / or home automation / home theater software system.
