Pro Video VGA-to-DVI Scaler

The Gefen EXT-VGA-DVI-SC converts analogue VGA signals to a digital DVI-I output. It accepts input resolutions up to 1920 x 1200 and scales them to 1080p60 or 1920 x 1200. An on-screen display menu provides configuration control. The unit draws a maximum of 2W from a 12V DC supply.

Replaces Analogue VGA Capture Chains

This converter removes the need for separate scan converters or capture cards when connecting legacy VGA sources to digital displays or recorders. The jump is worth it when a source only offers HD-15 output but the destination requires a digital TMDS link at 165 MHz pixel clock. It does not add new video information beyond the original analogue signal.

Compact Desktop Installation

The enclosure measures 4.9 x 1 x 3.2 inches and weighs 0.4 lbs, fitting easily on a rack shelf or desk. Power operates across a 6V to 24V DC range, so a compatible 12V nominal adapter is required. Common issues include mismatched aspect-ratio settings in the OSD and using a DVI cable that lacks the digital pins.

Questions about this item

What clearance does the 4.9" x 1" x 3.2" chassis need for the HD-15 and 29-pin DVI-I connectors?

Allow extra depth behind the unit for the VGA HD-15 and DVI-I 29-pin cables; the quoted dimensions exclude those connectors.

Which step is most often missed when powering the converter from a 12V DC source?

Confirm the supply stays within the 6V to 24V DC operating range and connects to the barrel jack before linking video sources.

How do I update firmware later using the Mini-B USB port?

Connect the Mini-B port to a PC, run the Gefen firmware utility, and follow the on-screen prompts to flash the new image.
