HDMI to DVI + Audio Extraction

The ESTONE converter takes a single HDMI input and splits it into a DVI-D video output plus both optical Toslink SPDIF and 3.5 mm stereo audio outputs. It is built for users who need to connect an HDMI source such as a PC, Apple TV, Blu-ray player, PS3 or PS4 to a display that only accepts DVI while also routing sound to an external amplifier or powered speakers. The unit handles 1080p resolution and passes DTS, AC3, PCM and LPCM audio formats without alteration.

Sustained Signal Handling

The adapter is a passive, unpowered device that relies on the source to drive the HDMI link and the display to terminate the DVI connection. Because it contains no active reclocking or equalisation circuitry, signal integrity over long cables depends entirely on the quality of the HDMI and DVI leads used. In continuous operation the converter simply passes the incoming TMDS stream through to the DVI port while simultaneously tapping the embedded audio packets for the optical and analogue outputs, so thermal load remains negligible.

Interface Practical Limits

Video is limited to the single-link DVI-D bandwidth inherent in a 1080p signal, so higher refresh rates or resolutions beyond 1080p cannot be transported. Audio extraction works only with formats carried in the HDMI audio infoframes — DTS, AC3, PCM and LPCM — and the optical output follows the SPDIF specification, which caps multichannel bitstreams at the standard SPDIF throughput. No HDCP management or EDID override is provided, so protected content may require a compliant display.

Questions about this item

Does the ESTONE converter draw enough power to warm up or make noise when running all day?

The unit is a passive adapter with no fan or active electronics, so it produces no audible noise and negligible heat during continuous use.

Which cables or displays must I already have to connect a DVI monitor and external speakers?

You need an HDMI source cable, a DVI-D cable for the monitor, and either an optical Toslink cable or a 3.5 mm stereo cable for audio output.

Will this converter pass 1080p video from an older PS3 or Blu-ray player to a DVI projector without scaling issues?

Yes, it supports 1080p input and outputs the same resolution over DVI-D, so legacy 1080p sources display natively on DVI projectors or monitors.
