WE have used the BM dvi to sdi, sdi to hdmi and hdmi to sdi converters for a while now. we own several different switchers for High res systems and HDSDI broadcast. These BM converters have been reliable with Macs and PCs both with every switcher system we own and routers with the exception of Panasonic 410’s and 400’s. with my mac hooked up HDMI to the BM converter i am set to 1080i@60 i am coming out sdi to a HD and going to a ForA, a Panasonic 410, a Analog way pulse, a Screenpro 2 a Encore, Pandora input card, a Barco sdi router and a BM sdi router and coming out sdi from a router to BM sdi to hdmi into monitors. all systems set to 1080I@59 and all see the computer and are able to lock except the Panasonic. this sounds like a issue Panasonic should be able to fix with a software upgrade.
