I've got a HDMI link set up between two Zybos using Digilent's DVI cores (rgb2dvi and dvi2rgb). Having tested everything successfully using a 1080p pipeline, however upon switching to VGA resolutions (640x480) the sink part cannot successfully decode the stream. It never occurred to me that low resolutions would pose an issue - but I've been banging my head on a wall with this one! As per the documentation, I've adjusted some constraints and multiplier / divider combinations for the MMCM in the dvi2rgb core and the clock recovery block is successfully recovering my 25.175 MHz pixel clock
