Signal conversion and purpose

This LUOM adapter converts an HDMI source into composite CVBS video at 480i or 576i plus analogue stereo audio through RCA and a 3.5 mm jack. It is built for owners of legacy TVs, VHS recorders or DVD recorders who need to connect modern streaming sticks, consoles or laptops. The unit only works from HDMI to RCA; it cannot reverse the signal path.

Installation experience

Power comes from an included USB cable and adapter, so a free USB port or charger is required alongside the HDMI and RCA cables. No drivers are needed — connect the source, select PAL or NTSC with the slide switch, and the picture appears. A common mistake is forgetting to power the converter or leaving the PAL/NTSC switch in the wrong position for the display region.

Interface limits

The HDMI input accepts signals up to 1920 × 1080 at 60 Hz but always down-scales to standard-definition composite output. Composite video cannot carry high-definition detail, so text and fine graphics lose sharpness. The 3.5 mm jack mirrors the RCA audio channels; it does not add surround sound or digital audio formats.

Questions about this item

How can I confirm the converter is outputting a proper CVBS signal after connecting it?

A stable picture on the composite display at 480i or 576i with sound from the 3.5mm jack shows the converter is working.

What items are included and what must I provide separately?

The box contains the converter, a USB power adapter with cable, and a user manual; you must supply an HDMI source, RCA cables, and a display with composite inputs.

Which output standard should I select on the PAL/NTSC switch for my region?

Choose NTSC for North America and PAL for most other countries to match the local TV standard.
