What it does well.
Overview
UGREEN model 40248 is an active, one-way converter for connecting an HDMI source to a VGA monitor, television or projector. Its built-in conversion electronics turn the source’s digital HDMI video into an analogue VGA signal up to 1920 × 1080 at 60Hz. Because VGA does not carry sound, the adapter provides a separate 3.5mm audio output. A Micro-USB power input can supply extra operating power when an HDMI source cannot power the converter reliably.
Key features
The points below describe the exact UGREEN SKU and the conditions required to obtain its stated performance.
01 Active conversion links an HDMI output on a computer or media source to a VGA input on an older display or projector.
02 Supports display modes up to 1920 × 1080 at 60Hz with compatible source, VGA cable and display.
03 Separate 3.5mm stereo output extracts compatible HDMI audio for powered speakers, headphones or an audio input.
04 Auxiliary Micro-USB power input helps with low-power HDMI sources or unstable/no-picture operation.
05 Compact attached HDMI lead reduces the number of rigid adapters protruding from the source port.
06 Plug-and-play hardware conversion does not normally need a computer driver.
Follow the one-way video, audio and power paths
The converter combines three separate connections. Mapping each path makes setup clearer and helps diagnose a blank picture or missing sound without reversing the adapter.
Video path Connect the source’s HDMI output to UGREEN 40248, then use a VGA male-to-male cable from the adapter to the display’s VGA input. Signal direction cannot be reversed.
Audio path HDMI audio is extracted to the adapter’s 3.5mm socket. Connect that socket to powered speakers, headphones or a compatible display audio input; the VGA cable carries no sound.
Auxiliary power path The converter normally draws operating power from HDMI. If a low-power source produces no picture or instability, connect the supplied Micro-USB lead to a suitable 5V USB power source.
Format path Select a resolution and refresh rate accepted by the VGA display, up to the stated 1080p60 ceiling. VGA image sharpness also depends on the cable and the display’s analogue adjustment.
Use scenarios
Use scenario 1 Connect a laptop or desktop HDMI output to a legacy VGA monitor for office work.
Use scenario 2 Present from an HDMI-equipped computer through a VGA-only meeting-room or classroom projector.
Use scenario 3 Use a compact computer or Raspberry Pi with a VGA display while routing audio to powered speakers.
Use scenario 4 Recover practical use from a sound VGA monitor when the source has HDMI but no analogue video output.
Setup and usability guidance
Confirm direction before purchase: the source must provide HDMI output and the display must accept VGA input.
Connect the adapter’s HDMI plug to the source, then connect a VGA male-to-male cable from the adapter to the display.
If sound is needed, connect powered speakers, headphones or the display’s audio input to the adapter’s 3.5mm jack.
Select the VGA input and start with 1920 × 1080 at 60Hz or a lower mode supported by the display.
If the picture is absent, flickers or the adapter repeatedly disconnects, connect the supplied Micro-USB cable to a suitable 5V USB power source.
Adjust image position and sampling from the VGA display’s own menu if analogue text or edges appear soft.
Compatible devices and systems
Compatible with HDMI-output sources such as supported laptops, desktop graphics systems, mini PCs, Raspberry Pi boards and media devices, and with displays or projectors that have a VGA input. The adapter does not work in reverse. Source format, copy protection and display timing must be compatible with the converter; protected media playback is not guaranteed. VGA is analogue, so final sharpness depends on the VGA cable and receiving display.
What this product does
- Converts an HDMI source’s digital video to an analogue VGA display signal.
- Outputs supported resolutions up to 1080p60.
- Provides a separate 3.5mm connection for compatible HDMI audio.
- Accepts auxiliary Micro-USB power when the source port cannot supply stable operating power.
- It does not convert VGA to HDMI and cannot be reversed.
- It does not carry audio through the VGA connector.
- It does not support 4K output, HDR or HDMI 2.1 formats.
- It does not upscale a low-resolution source into genuine Full HD detail.
- It does not include a VGA display cable or 3.5mm audio cable.
What to do
- Verify HDMI-output-to-VGA-input direction before ordering.
- Use a short, well-shielded VGA cable for the clearest analogue image.
- Connect Micro-USB power if a low-power source produces instability.
- Choose a refresh rate and resolution that the VGA display explicitly supports.
- Use the 3.5mm output when audio is required.
- Do not connect a VGA computer to an HDMI monitor with this model.
- Do not expect sound from the VGA socket.
- Do not force a high resolution into an older projector that cannot accept it.
- Do not assume protected streaming or disc content will pass through the conversion.
- Do not hot-pull the adapter by its attached lead or leave a heavy VGA cable unsupported.
Warnings and limitations
- Signal direction is fixed: HDMI source to VGA display. This is the most important compatibility check.
- VGA is analogue and does not carry audio, HDR, CEC or other HDMI data features.
- Some sources provide insufficient HDMI-port power; use the supplied Micro-USB cable when the converter is unstable.
- HDCP-protected content may fail because analogue conversion and the receiving display may not meet the content provider’s protection requirements.
- Regional sources list different attached-lead measurements, so installation clearance should be checked against the product images rather than an exact published length.

Questions buyers ask.
Which direction does the adapter work?
Only from an HDMI source to a VGA display. It cannot connect a VGA source to an HDMI monitor.
What is the maximum resolution?
The exact model is specified up to 1920 × 1080 at 60Hz with compatible source timing, VGA cable and display.
Does VGA carry the sound?
No. Use the adapter’s separate 3.5mm audio jack for sound.
Do I always need Micro-USB power?
Not always. Connect the supplied power cable when the HDMI source cannot provide stable power or the picture flickers or disappears.
Does it need a driver?
Normally no. The conversion hardware is built into the adapter.
Can it output 4K?
No. Its stated maximum is 1080p60.
Will it work with a VGA projector?
Yes if the projector accepts a supported VGA resolution and the source provides compatible HDMI output. Select the projector’s VGA input.
Can I use it for protected streaming video?
Do not rely on it. Protected content can fail because of HDCP or analogue-output restrictions.
Is a VGA cable included?
No VGA cable is listed. Supply a male-to-male VGA cable of suitable length.
What should I try if the image looks soft?
Use a shorter shielded VGA cable, select the display’s native resolution, run its auto-adjust function and add Micro-USB power if the signal is unstable.
