VGA and Audio to HDMI Scaler

The Gefen EXT-VGAA-HD-SC converts analogue VGA video and stereo audio into a digital HDMI signal. It accepts input resolutions up to 1920 x 1200 and outputs up to 1080p60 or 1920 x 1200. An on-screen display menu provides control over scaling and settings. This unit suits integrators connecting legacy PCs or AV sources to modern HDMI displays.

Simple desktop or rack installation

The converter measures 4.9 x 1 x 3.2 inches and weighs 0.4 lbs, so it fits on a shelf or in a rack tray without brackets. Connect the VGA HD-15 input, the 3.5 mm audio jack and the locking HDMI output, then apply 12V DC power. A common issue is forgetting that the HDMI connector locks; pull the release tab before unplugging to avoid port damage.

Check source resolution and power range

Verify that your source outputs a pixel clock no higher than 165 MHz and a TMDS clock within 225 MHz, matching the scaler's maximum specifications. The power input accepts 6V to 24V DC, so confirm your supply falls in that range and delivers at least 2.6W. Ensure the display accepts 1080p60 or 1920 x 1200 at 60 Hz for a stable handshake.
