HDMI to VGA Scaler Converter

The SIIG CE-H24R11-S1 converts a digital HDMI input into an analog VGA video signal and a separate stereo audio output. It accepts resolutions up to 1920 x 1080 and includes de-interlacing and noise reduction. A micro USB port allows firmware updates and software control, while a slide switch selects the operating mode. The unit is wall mountable and powered by a 100-240VAC adapter.

Suited for legacy displays and audio extraction

This converter fits users connecting modern HDMI sources to older VGA monitors or projectors that lack HDMI ports. It also serves installations needing a separate 3.5mm audio feed for external speakers. Buyers who require 4K or higher output resolution, or who need HDMI pass-through rather than conversion, should look at a different device.

Handles 1080p sources with headroom to spare

The scaler comfortably processes full HD signals at 1920 x 1080 and downscales them for VGA display. It runs out of headroom when the source exceeds 1080p, as the hardware does not support higher input or output resolutions. The 3.5mm jack delivers analog stereo only, so multi-channel digital audio formats are not preserved.
