MarkyMac Posted August 17, 2020 Share Posted August 17, 2020 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. debug_20954.zip Link to comment Share on other sites More sharing options...
MarkyMac Posted August 17, 2020 Author Share Posted August 17, 2020 Have tried multiple cables and monitors, before that's suggested Link to comment Share on other sites More sharing options...

MarkyMac Posted August 19, 2020 Author Share Posted August 19, 2020 Hey, thanks - that worked a treat! Good stuff. I really must get around to updating the E7470 to a newer OS - or may just wait for the fun of trying Big Sur at some point. Link to comment Share on other sites More sharing options...
