DVIGear DVI-3531a HDMI Converter Scaler

DVIGear's new AV-PC to HDMI Converter / Scaler is targeted towards custom installers and integrators who need a one-solution product to convert incoming audio and video signals to a single HDMI stream. This rather versatile unit can take either DVI-D, component or VGA (PC) input, along with an audio source, and convert the output to a single HDMI stream (with integrated audio). The system can also scale the video input to various output resolutions up to 1920x1200 @ 60Hz. It includes 3D motion-adaptive deinterlacing as well as high-quality analogue to digital converters to maintain audio fidelity throughout the conversion process.

DVI-3531a remoteEach input format supports its own stereo audio connection (RCA for component and separate 1/8-inch mini connections for the others). The selected input signal is converted to a digital HDMI signal with embedded audio. This unit accepts a wide range of input signal resolutions and support pixel clock rates up to 165 MHz. Most importantly, it provides user-selectable output resolutions (via on-screen display) up to 1080p and 1920x1200 (W-UXGA) using two high-performance internal scaling engines. Control is provided via the front panel or included IR remote control. Direct input and output source and resolution settings are possible from the remote, making macro programming a breeze.
