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.

Questions about this item

How do I confirm the EXT-VGAA-HD-SC is working after connecting my VGA source and HDMI display?

The on-screen display menu appears on the HDMI output, letting you verify the detected input resolution up to 1920 x 1200 and select an output resolution up to 1080p60 or 1920 x 1200.

What cables or accessories must I buy separately for the EXT-VGAA-HD-SC?

You need a VGA HD-15 male-to-male cable for video, a 3.5 mm stereo cable for audio, an HDMI Type A cable for the display, and a 12 V DC power supply capable of at least 2.6 W.

Which output resolution should I choose on the EXT-VGAA-HD-SC for a 1080p monitor?

Select 1080p60 in the OSD menu; the scaler accepts input up to 1920 x 1200 and will downscale or pass through to match the 1080p60 timing.
