The KanexPro SW-4X1SL18G is an UltraSlim auto-switcher with 4–input and 1-output which auto-identifies input resolutions of up to four HDMI devices to one 4K display supporting full 4:4:4 YUV color space and 18 Gbps of bandwidth.This switcher can be controlled from the front panel, IR Remote, or by sending RS-232 commands, the corresponding indicator will illuminate to show real-time switching status. It can transmit uncompressed 4Kx2K@60Hz 4:4:4 (at max) signal and supports HDMI 2.0 and HDCP2.2 compliant.

Auto Switching with HDMI® ARC function 

Each user can utilize their own HDMI cable and the system automatically “senses” when an input is attached and proceeds to distribute their input device live to the output display. As an added feature, it also provides ARC (Audio Return Channel).


The SW-4X1SL18G is ideal for residential AV and corporate applications, such as under the conference room table. From here, you can run up to four HDMI cables to different points on the table, and then connect your devices (e.g. laptops, tablets, and phones). The switcher handles user signal switching and distribution.
