To connect an HDMI source to a TV with yellow, red and white RCA inputs, use a powered HDMI-to-composite converter—not a passive cable. The yellow plug carries standard-definition composite video; red and white carry analog audio. Confirm HDMI-in/RCA-out direction, PAL or NTSC output, power, accepted source resolutions and HDCP compatibility.
HDMI and Composite RCA Are Different Signal Systems
| Element | HDMI side | RCA composite side |
|---|---|---|
| Video | Digital HDMI | Analog composite video on yellow |
| Audio | May be embedded in HDMI | Analog left/right on white and red |
| Typical display class | Modern source output | Legacy standard-definition input |
| Required bridge | Powered HDMI-input to composite-output converter | |
A passive wire cannot decode HDMI and create analog composite video. The converter must process the signal and normally scale it to a format the legacy display accepts.
Check HDMI In and AV Out Before Buying
Converters are directional. This page covers a modern HDMI source feeding a legacy composite display. The reverse job—an old game console or VCR feeding a modern HDMI television—needs RCA/composite input and HDMI output. See the red, white and yellow RCA-to-HDMI guide for that direction.
Do not confuse composite video with component YPbPr. Component uses three video plugs, while composite uses one yellow video plug. The HDMI-to-component converter guide covers that separate path.
PAL, NTSC and Resolution Need an Exact Match
Many converters include a PAL/NTSC switch. Select the format accepted by the display and region-specific equipment. A high-resolution HDMI source does not make the analog output high definition; the converter’s scaler and the display’s composite input set the result. Text and computer interfaces can look soft on a composite display.
Protected content may fail when the converter or display path cannot complete the required HDCP handling. Do not buy a converter that promises to bypass content protection.
Connect in a Controlled Order
- Set the converter to HDMI input and composite/RCA output direction.
- Connect the yellow video plug and matching red/white audio plugs.
- Provide the specified USB or external power.
- Select the television’s AV/composite input.
- Choose PAL or NTSC as required.
- Start with a conservative source resolution and test ordinary unprotected content.
Fix Black-and-White Video, No Picture or No Sound
- No picture: check direction, power, TV input and source resolution.
- Black-and-white or rolling picture: verify PAL/NTSC and the display’s accepted format.
- No sound: confirm red/white audio plugs and the TV audio input.
- Menus work but a movie fails: review HDCP compatibility and content restrictions.
- Poor text quality: composite video is a legacy standard-definition path; use a digital display where possible.
