HDMI to VGA + Audio Converter

The SIIG CE-H21811-S1 converts a digital HDMI source to analog VGA video and stereo audio. It supports PC graphics resolutions up to UXGA 1600x1200 and WUXGA 1920x1200. A 47-inch HDMI cable and a 5V power adapter are included in the package. The compact plastic housing measures 2.64 by 1.77 by 0.98 inches.

Suits legacy displays and audio systems

This converter is built for users connecting modern HDMI devices such as PCs, Blu-ray players or consoles to older VGA monitors or projectors. It also extracts stereo audio to a 3.5mm jack for speakers or receivers. Buyers who need to convert DisplayPort, DVI or analog sources should look at a different adapter. It does not upscale or downscale the incoming resolution.

Fits into an HDMI-to-VGA signal chain

The unit sits between an HDMI output and a VGA display input, drawing power from the supplied 100-240V adapter. It requires no software drivers and adds no extra cabling beyond the provided HDMI lead. The 3.5mm audio output frees the user from relying on monitor speakers or separate audio cables from the source device.

Questions about this item

Do I need a separate power outlet for the CE-H21811-S1 converter?

Yes, the included 5V/1A adapter plugs into any 100-240V outlet and powers the unit via its DC jack.

Will my older VGA monitor that only handles 1600x1200 work with this converter?

The converter supports up to UXGA 1600x1200 and WUXGA 1920x1200, so a 1600x1200 display is fully compatible.

How can I confirm the audio extraction is working after I connect everything?

Plug speakers or headphones into the 3.5mm jack; if you hear sound from the HDMI source, the audio path is active.
