yeah I've try it, when save as there are error appear. I don't know how to solve these error.
Thank you all you guys for help. Now I can close my laptop and open it while connected hdmi and not get black screen.
But I have the last question of my laptop, how to enable the HDMI audio?
I can using my laptop Internal Speakers, but I don't see any hdmi audio I can select, Also using IOREG to check, I find that my HDMI Framebuffer@1 connect type still 00 04 00 00 not 00 08 00 00 while hdmi is plug , but in my config, I already change the con1 type to 00 08 00 00.
How to solve it?This is my final problem of my laptop, other things are work completely such as sleep , WiFi, Bluetooth batteryshow etc..
