About turn on the laptop with the type-c device plugged(monitor)

[HeartAndSoul001]

First, thanks a lot for your EFI file sharing(Your EFI file is very comprehensive, and can bring a better experience about hacintosh on x1c 5th). Then, I use x1c 5th too, and this is my configuration (https://github.com/HeartAndSoul001/my-EFI-for-x1-carbon-5th/blob/master/README.md). And now, I have one question that the monitor built in will not be lighten when power on with type-c device plug(a 4k monitor). So, I want to consult you about it if you have the same problem too and please give me some advice. In addition, I want to consult you about how to open hidpi on external monitor. Looking forward to your reply as soon as possible >_<

What resolution is your built-in display? The EDID override in my config is for a 1080p one.

my built-in display is 1080p too. But I can not figure out it

I believe there are some patches for 4k output. You can get some additional infos in this issue I believe. The repo is for the 6th gen x1c, but it's basically the same machine and the repo is maintained by far more knowledgeable people than me.

ok, thanks a lot. I will share you if I figure out it _
