BMCC EF with Monitor Lilliput 667 GL SDI-HD

I just tried to connect my Blackmagic CC EF to a Lilliput 667 GL Monitor with the SDI-HD option, but it didn´t work. I just checked the Lilliput-Site and there is a chart with the specifications for each model, there I saw that that monitor model doesn´t support the signal that comes out from the camera via SDI. (Unfortunately the seller didn´t knew it.) What I´ll now try is to replace the monitor for another one like the Lilliput 665gl-70np and connect it to the camera through the Blackmagic Battery Converter SDI to HDMI.
Have someone any experiences with this kind of monitors and converters? Apparently it would work.

Out of Lilliput 7" monitors, the 663, 664, 665 and 5DII model ranges support Blackmagic Cameras. Using an SDI to HDMI converter should be no problem whatsoever.

However, I am having some image/firmware issues with a 663/O/P/2 I recently received that the manufacturer is still in the process of debugging so tread lightly.

I use the Lilliput 5D-II/O/P with my BMCC using a Atomos Connect S2H and have no problems, works fine

Thanks for the opinions and advices!
