displayport and vga hp elitebook 840g3

[joedu47]

Hello,
my pc is currently running under Macos sequoia.
When I plug the VGA port or the displayport on an external screen, nothing happens. No detection.
How do fix this?

my pc :
cpu I5 6200
graph hd520
ram 16 GB ddr4
disk 500 GB m2 sata
wifi/bluetooth broadcom bcm94360cs2 with adapter (wifi airport macbook air a1466)
opencore 1.0.2

Thank's

The HP 840 G3 is not compatible with this tutorial offered here so you cannot use it so base yourself on an existing tutorial for your G3
