SY-12H-4K22 - 4K HDMI scaler with dual outputs, HDR support, HDCP conversion, EDID tools, test patterns and OSD/RS‑232 control

4K HDMI scaler with dual outputs, HDR support, HDCP conversion, EDID tools, test patterns and OSD/RS‑232 control

The SY-12H-4K22 is an HDMI scaler designed to convert 1080p signals to 4K UHD or downscale from 4K UHD to 1080p, while maintaining digital audio synchronization. The OSD interface allows immediate control of functions directly through the HDMI outputs, simplifying in-field setup.

The input signal can be sent simultaneously to both HDMI outputs, even at different resolutions, or it can be replaced with an internally generated test pattern for quick display checks.

The device integrates full EDID and HDCP management, as well as event automation functions via RS-232 or CEC, making it suitable for installations requiring compatibility and advanced control. Control is via front panel controls (with on-screen OSD) or via RS-232.
