Why do I see menu information on the LCD and EVF, but not the HDMI output?
The RED ONE, as of Build 15, offers all outputs enabled, supporting a RED EVF, RED LCD, (3) HD-SDI outputs and one HDMI output simultaneously, with two of these outputs supporting full GUI overlay graphics. Default for GUI (menus) is RED EVF and RED LCD. If either monitoring option is not present, GUI overlay is available to the HD-SDI or HDMI outputs. So, the GUI overlay can only be sent to two monitoring options at a time.
