Adapter cable VGA + Audio to HDMI Secomp S3211, 0.23 m, VGA to HDMI with audio conversion

Secomp S3211 is a 0.23 m adapter cable that converts an analog VGA video signal together with a separate 3.5 mm audio input into a single HDMI output. It is designed to connect older PCs, laptops and media players that have VGA and headphone/line audio outputs to modern HDMI displays, TVs or projectors. The compact cable integrates video and audio conversion in one connector pair and is intended for short-distance desktop or AV rack connections when only HDMI input is available on the target display.

Advantages

The adapter cable provides a straightforward way to send VGA video and separate audio into one HDMI stream without requiring an external converter box. Its short 0.23 m length reduces cable clutter near workstations or AV equipment, and the integrated audio input ensures synchronized sound and picture on HDMI displays. The cable is plug-and-play for most systems and supports typical VGA resolutions appropriate for presentation and multimedia use.

Suitable for

• Connecting legacy PCs or laptops with VGA and 3.5 mm audio outputs to HDMI TVs or projectors
• Small meeting rooms and classrooms where HDMI-only displays are used
• Home entertainment setups that need to route older video sources to modern HDMI inputs
• Short desktop or AV rack connections where a compact adapter cable is preferred

When it may not be suitable

This adapter is not suitable for long-distance signal runs because the fixed short length is intended for close connections only. It does not add advanced scaling, upscaling, or support for digital-only features such as HDCP-protected streaming content; compatibility with protected digital streams depends on the source and display devices. For sources that require higher resolutions or specific digital copy-protection handling, a dedicated active converter or a different interface may be required.

Key specifications

• Cable type: VGA + 3.5 mm audio to HDMI adapter cable
• Length: 0.23 m
• Video signal: analog VGA input (converted to HDMI output)
• Audio input: 3.5 mm stereo jack
• Output: HDMI (combined audio and video)
• Use case: short-range desktop/AV connections for legacy sources

How to use

Connect the VGA connector to the source device's VGA port and plug the 3.5 mm audio jack into the source's headphone or line output. Insert the HDMI end into the HDMI input on the display, TV or projector. Power on the source and the display, then select the appropriate HDMI input on the display. Adjust the source output resolution to a VGA-supported mode that the target display accepts. If audio is not heard, verify that the source audio output is enabled and volume is raised.

What to consider before purchase

• Ensure the source device provides VGA video output and a separate 3.5 mm audio output
• Confirm the target display accepts HDMI input and supports the desired resolution
• Consider cable length — this adapter is short (0.23 m) and best for close connections
• Check whether protected digital content (HDCP) is required, as this adapter may not support all copy-protection scenarios

Usage recommendations

Use the cable for short, direct connections between legacy sources and modern HDMI displays. For best results, set the source to a standard VGA resolution that your display supports and ensure audio output is enabled on the source device.
