I have a VGA2USB LR, a few DVI2USB 3.0, and an AV io 4K. I haven't used the AV io 4K as much as the others. If you know, or can determine, the exact pixel clock and H and V active, front porch, back porch, and total values, you can configure the device for those exact pixel accurate capture values.
