Monoprice 130445 HDMI to 6G SDI Converter

This converter accepts HDMI signals up to 4K at 30Hz and outputs dual SDI streams for professional video workflows. It is designed for broadcast engineers and AV installers who need to integrate HDMI sources into SDI infrastructure. The unit automatically detects the input signal format for simplified setup. It includes an analog stereo audio input for embedding external sound.

Capacity and headroom for SDI bit rates

The device supports SDI bit rates of 270Mbps, 1.485Gbps, 2.97Gbps and 5.94Gbps including their 1.001 variants. It comfortably handles 480i, 720p, 1080i, 1080p and 4K@30Hz resolutions across both outputs. A built-in SDI re-driver extends cable runs without signal degradation. It runs out of headroom above 4K@30Hz or 6G SDI speeds.

Thermals noise and power in normal use

The compact enclosure operates silently with no moving parts during continuous conversion tasks. Power consumption remains low for a dedicated signal converter of this class. The 1.03 unit weight indicates a lightweight chassis suitable for rack or portable deployment. No active cooling is required under typical operating conditions.

Questions about this item

Will the 130445 work with my older 1080p HDMI camera and 270Mbps SDI monitors?

Yes, it accepts 1080p, 1080i, 720p and 480i HDMI signals and outputs matching SDI at 270Mbps, 1.485Gbps or 1.485/1.001Gbps bit rates for legacy displays.

How can I confirm the converter is passing a valid 4K@30Hz signal to both SDI outputs after installation?

Check that the source shows 4K@30Hz and each SDI monitor reports a stable 5.94Gbps or 5.94/1.001Gbps bit rate with no signal-loss warnings.

Does the 130445 package include the HDMI and SDI cables I need, or must I buy them separately?

Only the converter unit is included; HDMI and SDI cables plus a power supply for the barrel jack are purchased separately.
