Mirror Display in HDMI does not worki

[Mr Rager]

Hey guys, what's up.
So, I'm trying to fix my HDMI, but, until now, I couldn't.
I'm using Intel HD Graphics 620, and I got full Q/E on my laptop, but when I connect my HDMI cable, the TV shows without problem, but my laptop screen goes black, and even though I disconnect the cable, it does not come back, only restarting.

I got HDMI Audio working, but still have this issue and it's driving me crazy.

My Clover folder is attached.
Thanks!

Hi,

 

Can you provide some details about your system? A temporary solution is to adjust the OS settings to actually mirror the screen instead of projecting it on the external device. 

I see the Clover folder contains your complete ACPI, adjusting the PRW resources under iGPU if you renamed the devices (GFX0 otherwise) might resolve the issue also.

 

I have no option to look at iasl files at the moment and can not make edits. 

 

A recent topic, in which a user solved his problem might be usefull, it was about USB, but might for your issue also (Under GFX0 ofc) ; http://www.insanelymac.com/forum/topic/326980-immediate-wake-from-sleep-wake-reason-gbe-usbe/

So..  first things first.

 

Specs:

 

Dell Inspiron 7460

120GB SSD ADATA

i5-7200U 2.5 until 3.1 turbo.

Intel HD Graphics 620 

Nvidia 940MX (disabled using APCI files)

ALC256

Realtek 8111

Resolution: 1920x1080

macOS Sierra

 

 

In my preferences it's checked "Mirror Displays", and still, does not work.

I'm gonna take a look at the topic.

Thanks!

Did the changes you said, did not worked.
I think it's related to Framebuffer, but have no idea on data to "Find" and "Replace" like this one: http://www.insanelymac.com/forum/topic/327119-no-hdmi-video/

Intel HD Graphics 620. 
When I connect the HDMI cable, it's work perfect in the TV, but my laptop goes black, and do not turn back even though I disconnect the cable (only restating).
Thanks.
