Dell Latitude E5530 vPro, i5 Ivy Bridge, 8 Gb RAM, 128 Gb SSD, Intel HD4000 - El Capitan 10.11.3.
I need help to enable HDMI video output from my laptop to ACER 24" external monitor. I have previously had A17 BIOS, but I followed Jake Lo's advice to downgrade BIOS in order to get rid of boot glitch. I followed the steps from A3 to A12, and now I am running A12 BIOS.
I really need external monitor because I am visually impaired.
Here is my EFI folder in zip format:
