In my challenge I'm employing a CM2009 IC between true VGA controller and VGA output connector. It is mentioned from the datasheet for this IC that I can use EMI filters on HSYNC, VSYNC and DDC channels suitable right after IC and before VGA connector. Nevertheless there aren't any specs https://acxionphentermine15mg30ta69808.blogdosaga.com/31146534/emi-filter-purpose-an-overview
