Have looked at lots of guide, forum posts, and solutions, none of which have worked for me so far.
I have a perfectly working E7470 on High Sierra. BT, Wifi, Sound, brightness etc all fine. But connecting an external display via miniDP or HDMI has no effect. Doesnt work at boot time, after standby, or at any other time.
Debug files attached.
This isn't a killer problem for me, as I generally use the laptop as a laptop, but it would be nice to know I could use a display if I needed to. Thanks for any help in advance.
