Administrators Bronxteck Posted October 19, 2019 Administrators Share Posted October 19, 2019 i guess it needs the display to be reinitialized. why i do not know but display port tends to have this quirk. 1 Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted October 19, 2019 Moderators Share Posted October 19, 2019 This was noted in my E7x70 guide. It only happens on clean boot. If system has slept once, it won't happen. You could try adding EDID, it worked on my E7270 but not my E7470. You don't really need to put it to sleep, just close lid, the external monitor comes on as primary. You can then open the lid and it'll swap back. 1 Link to comment Share on other sites More sharing options...
