<key>PciRoot(0x0)/Pci(0x2,0x0)</key> <dict> <key>AAPL,ig-platform-id</key> <data> AACbPg== </data> <key>AAPL,slot-name</key> <string>Internal@0,2,0</string> <key>device-id</key> <data> mz4AAA== </data> <key>device_type</key> <string>VGA compatible controller</string> <key>enable-hdmi20</key> <data> AQAAAA== </data> <key>framebuffer-con1-alldata</key> <data> AQUJAAAIAACHAQAAAgQKAAAIAACHAQAA </data> <key>framebuffer-con1-enable</key> <data> AQAAAA== </data> <key>framebuffer-patch-enable</key> <data> AQAAAA== </data> <key>framebuffer-unifiedmem</key> <data> AAAAgA== </data> <key>model</key> <string>Intel Iris Plus Graphics 655</string> </dict> 

But i still didn't get any HDMI output , i try to plug in my HDMI device to this laptop and open Hackintool to check at the Patch -> Connectors Section , but i only found that LVDS is green light which is connected to my internal screen of my laptop. But HDMI wont light up and it seems to be a little lag when i plug in HDMI but just for 1 -2 seconds then it will be smooth again for cursor on my internal screen. (Pic 3)

Any solution to solve this problem?
