swanduron Posted November 8, 2020 Share Posted November 8, 2020 (edited) Hello experts, There is a problem confused me weeks and I cannot resolve it via Google and my experiences. My platform is HP 800G1 USDT with I5-4670 @ Intel HD4600 Core display card. Device boots very quickly when 1 DP monitor connected but experiences dead booting loop when 2 DP monitors connected. Of cause, 2 DP monitors works fine when device booted up with 1st DP monitor and then 2nd DP monitor plugged, no freeze and crashing during sleeping and wake up. Attached my EFI and anybody can tip me a point about this? Regards~~ config.plist Edited November 8, 2020 by swanduron Quote Link to comment https://www.insanelymac.com/forum/topic/345639-device-gets-continues-rebooting-when-2-dp-monitors-connected/ Share on other sites More sharing options...
swanduron Posted November 8, 2020 Author Share Posted November 8, 2020 Re-attach EFI folder as zip file here. This EFI is refined by @Donw35 's hot post, but this post also has this problem.
