Key features
Product highlights
1080p60 Maximum stated HDMI output from a compatible VGA source.
Audio sync Separate 3.5mm input embeds analogue audio into HDMI.
USB-C power Required power input for the active conversion electronics.
One-way VGA source to HDMI display only—not HDMI to VGA.
Video, audio and power have separate inputs
At a glance
VGA male video input. Connects directly to the VGA output on an older desktop, laptop or other source.
HDMI female output. Accepts a standard HDMI cable leading to an HDMI monitor, television or projector.
3.5mm audio input. Takes analogue audio from the source headphone or line output so sound can be combined with HDMI.
USB-C power input. Supplies operating power to the converter. It does not carry display video or ordinary USB data.
Convert an analogue VGA source to a digital HDMI display
ACTIVE CONVERSION
Use the converter when an older computer provides VGA but the available monitor, television or projector accepts HDMI. Internal electronics convert the analogue picture into a compatible digital HDMI output.
Direction is fixed. HDMI-to-VGA requires a different converter with HDMI input and VGA output; merely turning this unit around cannot change its electronics.
- VGA source only
- HDMI display only
- Up to 1920 × 1080 at 60Hz
- Lower supported resolutions can be selected
- Standard HDMI cable required
Add the sound that VGA cannot carry
SYNCHRONISED AUDIO
VGA transports picture but not audio. Connect the supplied 1m 3.5mm cable from the computer's headphone or line output to the converter, and the unit can combine that audio with the converted HDMI signal.
Select the computer's analogue audio output and set a volume level accepted by the destination. If the picture works but sound does not, check the 3.5mm cable and operating-system playback device before changing the HDMI connection.
- 3.5mm audio cable listed at 1m
- Audio source must be enabled
- HDMI destination must support the incoming audio format
- No microphone or audio-return function
Power the conversion electronics for a stable signal
REQUIRED USB POWER
Connect the supplied 1m USB-C power cable to a suitable USB power source. The converter needs this power because VGA alone does not provide the electrical supply required for active analogue-to-digital conversion.
The USB-C socket is power-only in this workflow. It cannot replace the VGA source connection, send files or charge a laptop.
- USB-C power cable listed at 1m
- Use a stable USB power source
- No driver normally required
- Power must remain connected during operation
- USB-C carries no video here
Use scenarios
Real-world workflows
Extend the useful life of VGA source equipment
Older office PC. Connect a VGA-only desktop to a newer HDMI monitor while combining its 3.5mm audio output with the picture.
Classroom projector. Display presentation material from a VGA laptop on an HDMI-equipped projector using a standard HDMI cable.
Equipment console. Connect a compatible VGA-output workstation or control computer to an HDMI display for monitoring.
Temporary replacement display. Use an HDMI television or monitor when the original VGA display is unavailable, subject to supported resolution and aspect ratio.
Compatible devices and systems
Compatibility
For VGA sources and HDMI destinations
Windows computers. Works with listed Windows versions from XP through Windows 11 when the system provides a working VGA output and compatible resolution.
macOS and Linux systems. Compatible systems can use the hardware when they expose a VGA output and allow the required display and analogue-audio settings.
HDMI displays. Connect a monitor, television or projector that accepts 1080p60 or another mutually supported HDMI mode.
USB power sources. Use a stable USB power source with the included USB-C power cable; USB-C performs no data or video role.
Check before buying

- It does not act as a capture card, splitter or multi-display adapter.
Setup and usability guidance
Guided connection
Connect VGA, audio, power and HDMI in a clear sequence
- Set the VGA source to a standard supported resolution, starting with 1920 × 1080 at 60Hz or 1280 × 720 if compatibility is uncertain.
- Connect the converter's VGA male plug to the source's VGA output and tighten the retaining screws gently where available.
- For sound, connect the supplied 3.5mm cable between the source headphone/line output and the converter audio input.
- Connect the supplied USB-C power cable from the converter to a stable USB power source.
- Connect a standard HDMI cable from the converter's HDMI female output to the display.
- Select the correct HDMI input and choose the analogue audio output on the source computer.
- If the display remains blank, test a lower standard resolution and known-good HDMI cable.
Do and avoid
Good practice
- Use the converter only from VGA source to HDMI display.
- Keep USB power connected throughout operation.
- Use a short, sound HDMI cable rated for 1080p60 or higher.
- Select a standard VGA resolution accepted by the HDMI display.
- Connect the 3.5mm audio lead when sound is required.
- Secure the VGA screws without overtightening and support the cable weight.
- Do not connect HDMI as the source or VGA as the destination.
- Do not expect USB-C to carry video or files.
- Do not operate without stable USB power.
- Do not force 4K or a refresh rate unsupported by the source and display.
- Do not hot-plug damaged, loose or wet connectors.
- Do not pull the converter by its leads or leave heavy cables hanging from a computer port.
Warnings and limitations
Safe operation
Safety note 1. Using the converter in reverse will not work because the electronics are directional.
Safety note 2. VGA is an analogue signal. Picture quality cannot exceed the source output and may be affected by VGA cable quality, noise and source hardware.
Safety note 3. If power is unstable, the HDMI display can flicker or disconnect. Test another USB power source and cable connection before replacing the converter.
Safety note 4. If sound is absent, verify the 3.5mm connection and select the correct playback output; changing HDMI settings alone will not create audio from VGA.
Safety note 5. Disconnect the unit if there is unusual heat, smell, damage or looseness at any connector.
Research and source note
Exact-model verification
Exact SKU 50945 and its matching CM513 media verify one-way VGA-to-HDMI conversion, separate 3.5mm audio, required USB-C power and 1080p60 maximum. The included 1m audio and power leads do not replace the separate HDMI cable.

In the box
A standard HDMI cable from the converter to the display is required and is not verified as included. A USB power source is also required; the listing verifies the USB-C power cable, not a mains adapter.
Questions buyers ask.
Which direction does the converter work?
It works from a VGA source to an HDMI display only. It cannot convert an HDMI computer output to a VGA monitor.
What is the maximum resolution?
The maximum stated output is 1920 × 1080 at 60Hz. Lower standard resolutions can be selected when required.
Does it support 4K?
No. This model is a Full HD converter with a 1080p60 maximum.
Why is USB-C power required?
The internal electronics actively convert analogue VGA to digital HDMI and need external power. USB-C supplies power only.
Can USB-C carry the video instead of VGA?
No. Video input is VGA. The USB-C connection does not transfer video or ordinary USB data.
How do I get sound over HDMI?
Connect the supplied 3.5mm cable from the source's audio output to the converter, then select that analogue output in the operating system.
Does VGA itself carry audio?
No. VGA carries video only, which is why the separate 3.5mm audio connection is required.
Is an HDMI cable included?
A standard HDMI cable is required but is not verified as included. The listing verifies a 1m USB-C power cable and a 1m 3.5mm audio cable.
Does it need a driver?
The converter is designed for plug-and-play use on the listed Windows, macOS and Linux systems. The source must still provide a working VGA output.
Why is the picture unstable or absent?
Check USB power, VGA seating, HDMI input, cable condition and source resolution. Start with a standard lower mode and add audio only after video is stable.
Can it split one VGA source to several HDMI displays?
No. It provides one HDMI output and is not a splitter or multi-display controller.
