HDMI and VGA to 3G-SDI conversion

The Gefen EXT-HDVGA-3G-SC converts HDMI and VGA sources with analog audio to a 3G-SDI output. It scales input resolutions up to 1920 x 1200 and 1080p60 to a 1080p60 SDI signal. An on-screen display menu provides configuration and EDID management. Locking HDMI and standard VGA connectors ensure secure connections.

Installers bridging HDMI or VGA to SDI workflows

This unit suits AV integrators sending computer or camera signals over SDI cable runs. It accepts a 6V to 24V DC supply for flexible power integration. Buyers needing 4K resolution support or multiple simultaneous inputs should look at alternative devices.

1080p60 maximum output resolution

The converter scales all incoming video to a maximum output of 1080p60. The SDI pixel clock reaches 150 MHz while HDMI and VGA inputs accept up to 165 MHz. This ceiling determines compatibility with downstream SDI equipment.

Questions about this item

Should I use the HDMI or VGA input for my 1920 x 1200 source?

Both inputs accept up to 1920 x 1200 at 60 Hz; choose HDMI for digital signals with locking connector or VGA for analog sources.

Will the 1080p60 SDI output handle fast motion from a 1080p60 camera feed?

The scaler outputs 1080p60 over 3GSDI at a 150 MHz pixel clock, matching the input frame rate without frame drops.

Does the 12V DC supply limit cable length for the SDI run?

The unit operates from 6 V to 24 V DC and draws 5 W maximum, so standard 3GSDI coax distances are unaffected by the power input.
