It is compatible with resolutions of up to 2048x2048 (2560x1600) and can capture computer generated images at a rate of up to 60 frames per second using an on board state-of-the-art lossless compression algorithm, making it ideal for precision applications such as air traffic control.
Key Features
- Captures dual link DVI and single link DVI video signals
- Supports resolutions up to 2048x2048 or 2560x1600 in widescreen
- Able to capture video from HDMI1 sources with adapter

DVI2USB Duo is the world's fastest dual link DVI capture device.
Being a frame grabber specifically made for those that need to capture the high-quality and high-resolution of a dual-link DVI video signal, DVI2USB Duo acquires frames at a transfer rate of up to 330 megapixels per second, compressing the stream on-the-fly and transfer compressed stream onto a computer using USB interface. It then has the ability to record and/or transmit these images over public, private or broadband wireless networks, enabling remote diagnosis of high resolution medical displays, air traffic control displays, control room monitors, and other situations in which a precise image is required for accurate decision-making or replay.
DVI2USB DUO uses Epiphan Systems' cutting edge compression algorithm in order to provide lossless 100% quality images. DVI2USB DUO also allows you to:
- Capture at a rate of up to 60 frames per second depending on content being captured.
- Capture dual link DVI and single link DVI video signals from any device.
