did add these three patches to KextToPatch of config.plist.
Still no output for HDMI!
Kindly check the attachment.

You have to rebuild caches and reboot a couple of times to be sure.

Rebuilt caches multiple times, tried with nocaches as well.
Even after constant reboot, no signal on HDMI.

No information here regarding the HDMI video output and the restart issue.
Any ideas on that?

For HDMI output, you first need to determine which graphics device HDMI is connected to.
Do that in Windows.
Then you'll know whether to approach the problem with Nvidia drivers, or Intel HD kext patches.

You will need to describe the "restart issue" in detail. No one here is clairvoyant.

I will note from your ioreg that you did not implement backlight control yet...
Also, no CPU PM either.

Your config.plist is wrong in many ways... See guide for better starter plists:

In windows, HDMI connects via the nvidia 970m:

Okay, so when i restart, this is the verbose that flashes for just a second,

after that it gives black screen for some time, with keyboard backlights on, and then it boots and gets stuck on the alienware logo for a long time.
After that sometimes it boots and other times it shows this error:

The other restart issue is that, whenever i change anything on clover, and boot again, i get this:

then i have to inject the fake id and run this command
sudo touch /System/Library/Extensions && sudo kextcache -u /
and then at the next boot everything is fine.

I will note from your ioreg that you did not implement backlight control yet...
Also, no CPU PM either.

No havent done the backlight control, was checking thread on how to do.
For CPU PM, i just checked plugintype=true from clover bootloader. is this correct or do i need to run the sshdtprgen script?

Your config.plist is wrong in many ways... See guide for better starter plists:

I worked so much to add things one after the other from the starter plists. Starting again would be disastrous with my level of experience, what i have done wrong? i can remove those things.

All of your help is highly appreciated Rehabman, even at this stage that i am wouldnt be possible without you.

In windows, HDMI connects via the nvidia 970m:

Then it is nonsense to try and patch the Intel graphics kexts in order to fix HDMI...
You will need to get the Nvidia drivers working.

I installed the latest nvidia drivers supported for my os. But again, HDMI output is the least amongst priorities.
Kindly check my other problems to see if something strikes to you as a problem that can be solved.

You will need to be specific regarding "other problems".
Work on one thing at a time... don't jump around to different things.

This is the issue at number 1 priority.

When im disassembling the DSDT, and then trying to compile, there are just TONS of errors. Have no idea whats going on. Kindly try to do the same on your side and see.
