Hello there,
I have a quite annoying problem.
I'm trying to attach 3rd display to my GL504GS via Mini DisplayPort to VGA adapter (v1.2) but have no signal at all (not even that characteristic plug and play sound).
Adapter works fine with Surface Pro 4 so it's not its fault.
I have tried a soultion based on nvidia bios drivers
https://www.nvidia.com/object/nv-uefi-update-x64.html, but installation is aborted with a short "[...] update is only for add-in graphic cards" notice.
Can somebody help me?
GeForce driver v431.60 (GTX1070)
HDMI works just fine
