Dell inspiron 7737 video hdmi output & backlight control not working - Help.

[RehabMan]

Tried it, keyboard works. but messed up with HDMI port. connecting to external monitor. not working anymore. So I roll back my code.

That patch will not interfere with HDMI.

That patch will not interfere with HDMI.

I am not sure what could be wrong.

I just followed the same way to patch DSDT.dsl, copy the code to patch window and apply the code.
for SSDT-7.dsl and SSDT-8.dsl. there is nothing could be applied.

Then I created DSDT.aml, SSDT-1.aml, SSDT-2.aml also with /extra/SSDT.aml

replacing the files in EFI/CLOVER/Patched.

I attached new DSDT as DSDT.aml.KB --- with keyboard fix, but broken HDMI
old DSDT as DSDT.aml.HDMI --- no keyboard fix, but with working HDMI.

With DSDT.aml.KB, When I connect HDMI. external screen has no signal. internal screen is messed up.

Really appreciated for help.

You must be changing more than that single change.

You must be changing more than that single change.

I really cannot understand where could be the wrong point.

Let me repeat what I did -- I have
DSDT.dsl, SSDT-7.dsl and SSDT-8.dsl in My Desktop DSDT folder.

Those are the codes that applied with existing patches which make HDMI and other things working.
No compiling errors. I use them to create DSDT.aml, SSDT-1.aml, SSDT-2.aml, plus existing SSDT.aml
from /EXTRA folder. Those 4 files make my Dell 7737 working almost perfectly.

That is my start point

Now I just open DSDT.dsl, click "Patch" to open patch window, copy and paste nguyenmac's keyboard fix patch.
Then apply the patch. close the patch window. compile code, no error. save as DSDT.aml (binary code). Apply the same patch to SSDT-7.dsl and SSDT-8.dsl (actually nothing can be applies).
then create SSDT-1.aml, SSDT-2.aml

Now I have new DSDT.aml, SSDT-1.aml, SSDT-2.aml, plus existing SSDT.aml
from /EXTRA folder.

Test them, keyboard behavior is now just working as I expected -- working perfectly. HDMI? external monitors? --I tested with 2 of my external monitors. No signal on either of them.

Roll back with my previous DSDT.aml, SSDT-1.aml, SSDT-2.aml, and SSDT.aml. Both external monitors works perfectly with my Dell 7737 HDMI port.

Pull my hair straight -- what is the place I overlooked. ( I repeated my test twice, started from scratch for each test)

Really appreciated.

The patch is only for DSDT.

Post /Extra folder for working and non-working setups.

 

[jzhang19]

The patch is only for DSDT.

That is obvious. nothing could be wrong here.

Post /Extra folder for working and non-working setups.

When I get back home tonight, I will post it for both cases.

Appreciated.

Evidently not so obvious as you attempted to apply the patch to your SSDTs...

OK.

OK.

In my /Extra folder, there is only one file SSDT.aml

it is created at the early stage when I setup this machine, afterwards, it seems never be updated.

I use Clover, I guess you want me to post Clover folder, not /Extra folder.

Clover does not use /Extra, so you really shouldn't even have an /Extra folder.

I see no material difference that would cause HDMI not to work.

I do notice that you forgot to use config.plist/ACPI/SortedOrder to specify the order of your SSDTs, so they may be loading out of order. It means your SSDTs will load in the order in which they appear in the FAT directory entries, which is a bit hard to predict.

That is the reason I am really getting confused.

Sure, let me try that tonight.
