Whereas the VGA2USB does exactly what you expect it to do, the DVI2USB is actually special. Not only is it a USB 2.0 device that can capture a DVI signal, but it is also a device that can capture an analog RGB signal. The DVI2USB also captures images at the full 24-bit color. More importantly, the DVI2USB has an integrated memory buffer that fixes the problem of motion artifacts during the capture stream.
