UGREEN CM513 50945 • VGA TO HDMI CONVERTER
Bring a VGA computer onto a modern HDMI display—with audio
UGREEN 50945 actively converts analogue VGA video and a separate 3.5mm audio feed from an older computer into one HDMI output up to 1080p at 60Hz. The converter requires USB-C power and works only from VGA source to HDMI display.
Product overview
Overview
A clear view of the product before you connect it
This is an active signal converter for a specific legacy-to-modern direction. The VGA male connector receives analogue video from a computer or other VGA source, the 3.5mm cable supplies separate analogue audio, and the electronics combine them into a digital HDMI output for a compatible monitor, television or projector.
The maximum stated output is 1920 × 1080 at 60Hz. Lower VGA resolutions can be used when supported by the source and display. Because VGA carries no audio, the 3.5mm connection is required when sound is wanted over HDMI.
The converter also needs power through its USB-C power connection. That USB-C port does not receive video or USB data. This model cannot be reversed to connect an HDMI computer to a VGA monitor.

At a glance
Video, audio and power have separate inputs
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.
ACTIVE CONVERSION
Convert an analogue VGA source to a digital HDMI display
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
SYNCHRONISED AUDIO
Add the sound that VGA cannot carry
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
REQUIRED USB POWER
Power the conversion electronics for a stable signal
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

- Secure the VGA screws without overtightening and support the cable weight.
What not to do
- 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.
Safe operation
Warnings and limitations
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.
