Overview
- The Simplecom CM353 is a three-input, one-output HDMI switch built for modern high-resolution displays. It enables three separate source devices—such as streaming boxes, gaming consoles, Blu-ray players, or computers—to connect to a single HDMI port on your TV or monitor without constant cable swapping.
With full HDMI 2.1 compliance, the CM353 handles cutting-edge resolutions: 8K at 60Hz, 4K at 120Hz, or 1080p at 240Hz. The 48Gbps bandwidth supports HDR content, high-quality audio formats including Dolby TrueHD and DTS-HD, and deep colour (up to 16-bit). HDCP 2.3 encryption ensures content protection for streaming services and protected media.
Setup is straightforward—the integrated 40cm HDMI output cable connects directly to your display, and the included remote control lets you switch between inputs instantly without reaching behind your TV. No external power is needed for standard HDMI operation, making installation clean and cable-free.
Note: To achieve 8K@60Hz or 4K@120Hz performance, use certified 48Gbps HDMI 2.1 cables with a maximum length of 3 metres. This is a one-way switch only and cannot be used in reverse.
