I have a had a search and cannot find this out so here goes.. I have several sources to my HDP and have been using the RGBHV outputs to my barco 808 Port 5 at 720p 72hz no problem.. I now wish to use HDCP sources so needed a solution, So I bought the HDFury and if I fit that to the End of the DVI cable and then port 5 I get no picture at all from the Lumagen, no inbuilt menus, nothing! The HDFury has a blue light confirmation of HDCP handshake. I have learnt that some Barco's require negative sync and this comes from the source, my source being the Lumagen, so why does it work with RGBHV output and not DVI output ? is it possible to set the Sync polarity on the Lumagen(I am using latest FW) ? if so how?
