blackmetallive Posted July 16, 2017 Share Posted July 16, 2017 hi guys, can anybody help me? i have a strange problem: my sierra hackintosh is working great, except HDMI: - when i plug in HDMI cable (connected with TV), the picture "jumps" to the TV, the laptop screen freezes - only TV is active now (but its working, sound, picture etc) - i do not have option in macOS settings for 2 screens, mirror, extend etc, the "Arrangement" tab in screen settings is missing - when i unplug HDMI cable, TV gets black but picture does not return to laptop, i have black screens, need to restart to get screen back to laptop - i already tried to inject connector types with SSDT patching, then i see in IOReg that i successfully injected them but nothing changes System: Asus ROG G751 JY intel i7 4720 HQ nvidia gtx 980m thx in advance Link to comment Share on other sites More sharing options...
SavageAUS Posted July 16, 2017 Share Posted July 16, 2017 Do you just have Nvidia graphics or Intel as well? Sent from my SM-G930F using Tapatalk Link to comment Share on other sites More sharing options...
blackmetallive Posted July 16, 2017 Author Share Posted July 16, 2017 only nvidia, no intel HD i found out it works if i put SMBIOS to iMac 14,1 and boot with HDMI connected, then i have 2 displays working together (but if i unplug HDMI, both are black again, screen not jumping back to laptop, i have to plug in HDMI again and use the TV to reboot) some people from internet told me to inject connector types for LVDS, HDMI, DP with SSDT patches. i did it, nothing changed. now i found something like Lilu.kext and NvidiaGraphicsFixup.kext, have to try this. but this behaviour is really strange Link to comment Share on other sites More sharing options...
