My external monitor shows no info., when I connect my a7rII to it via HDMI... I enter the menu and turn the HDMI info. Display "ON", but it always changes to "OFF" itself every time my external monitor is connected. And, the HDMI info. Display turns dark and unchangeable. How to make the external monitor show all info.? btw, the monitors I've tried are Sony CLM-FHD5 and Ikan potkeys 5".
