Hi there, My laptop info here: Dell Inspiron 15R 5520 Core i5 3210M - 8GB RAM - SSD 120GB - BCM943225HMB - Intel HD4000 & AMD 7670M - 1366x768 I'm on El Capitan. My issue is that the VGA port doesn't work. I asked my friend and he said because the discrete graphic card control the VGA port and it's disabled then VGA port doesn't work. Is it true? Does the 7670M controls VGA port? How to check and verify it? If it's not then how to get my VGA port worked? Thank you
