I'm sure someone can explain it much better than I, but not all monitors will work with the BMCC.
I have a 19" TV that I was using for framing and it does not accept the signal through HDMI after it passes through an SDI to HDMI converter. My other TVs and Monitors however, work fine.
I believe it comes down to progressive vs interlaced signal out of the BMCC and what the monitor accepts. I could be wrong on this but for example I believe the SDI out for 29.97 is actually 59.94i, don't know if its the same for other frame rates. Usually cheap monitors wont be compatible.
Not saying it wouldn't work, just sharing my experience. Goodluck!
