Converter and Switch for Legacy Displays

This unit combines an HDMI-to-HDMI pass-through with a CVBS downscaler. It accepts a single 1080P source at 60 Hz and simultaneously feeds a modern HDMI display plus an analogue composite output. The aluminium housing measures 115 by 100 by 25 mm and weighs 360 g. It is powered from a standard DC 5 V 1 A USB supply.

1080P 60 Hz Input with Dual Output

The decisive specification is the 1080P 60 Hz HDMI input that drives both an identical HDMI output and a CVBS composite video signal at 480i or 576i. Stereo analogue audio is provided through RCA left and right connectors. The scaler supports both PAL and NTSC television standards and complies with HDMI 1.3.

Plug-and-Play Hardware Conversion

No driver installation is required; the device operates purely through hardware conversion. A zoom button on the enclosure adjusts the picture size on the composite output. Ensure the USB power cable is connected to a reliable 5 V source, as insufficient current can cause signal drop-out on the analogue ports. The HDMI pass-through remains active even if the composite side is unused.

Questions about this item

Will my 1080P/60Hz HDMI source display correctly through the converter?

The unit accepts 1080P/60Hz on its HDMI input and passes the same 1080P/60Hz signal through the HDMI output, so the original timing is preserved.

Does the HDMI 1.3 compliance limit the resolution or refresh rate I can send?

HDMI 1.3 supports up to 1080P/60Hz, which matches the converter's rated input and output, so no further restriction is imposed by the interface.

What are the exact dimensions I need to clear for mounting this converter?

The aluminium-alloy case measures 115 mm long, 100 mm wide and 25 mm high, so allow at least that footprint plus cable bend radius.
