Hello Everybody
My E5470 is with High Sierra onboard
VGA port on laptop works
HDMI port on laptop works (audio too)
My Docking station (Dell pr03x) works almost fine: audio, usb, lan perfectly recognized
I've connected 2 external DELL monitors to the docking station with a DVI cable; the result is:
Laptop display works, external monitors work too but they are in mirroring between them
So it's still like I have 2 monitors: The laptop display and one external extended (the other one is in mirroring). On System Pref - Monitor I can see 2 monitors only (when I click to the external one, the red square appers in both external connected).
I tried to connect one of the 2 external monitor using a VGA cable instead of the DVI but the result was always the same: the 2 external monitors were in mirroring.
I followed some guides (for del E6xxx series) in this forum, but unsuccessfully (probably because the video adapter is not the same).
Someone of you can help me to use these 2 external monitors in "extended mode"?!?
Thanks in advance
PS: I tried with another docking station, model PR02x but the result was always the same
