Problems getting full frame video to monitor

[Eduardo Cayo Chioino]

hi,
Could anyone help me. I've having a problem getting a signal out to my monitor. Even in underscan, it's impossible for me to get the full frame of my screen information (I'm missing the bottom of the frame, critically the stoplights and histogram). I am going from the RED HDMI into a 720P monitor. I have tried preview and hdsi to no avail.
We are shooting steadicam and so we have an AJA downconverter, so on many days we will be going from the HDMI signal into an AJA downconverter, to a SD def signal, and ultimately into the same monitor via the RCA video in cable. I have tried this set-up and still I am missing fullframe video.
If anyone could help me I would gratefully appreciate it. In advance, thank you, thank you, thank you.

I believe that this information is not available on any of the BNC outs.

are you using EVF and LCD?

You need to switch SYSTEM-MONITOR-PREVIEW to "Menus"; however if your HDMI converter doesn't like the signal it won't work.
