There is no hidden menu to enable/disable the HDMI port on AJ-PX270.
Please keep in mind though that standard definition signals are converted from interlace to progressive before outputting to HDMI. Just make sure your monitor accepts progressive SD signals. Also, some indicators like center marker, expanded display, safety zone, etc. are not displayed on the HDMI (or SDI) port.
But what seems to be most important is that there is no output from HDMI port if you set your camera to 1080-23.98PsF mode.
I don’t know where are you located but if by any chance you’re in UK then you can visit us or send the camera to our service center to test it, perform diagnostics, etc.
