Try with FakeID 0x68e01002 AND with FixDisplay_0100

You'll also need to edit the DSDT and change layout to 13 (OD) in device HDEF :

            Device (HDEF)
            {
                Name (_ADR, 0x001B0000)  // _ADR: Address
                Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
                {
                    Store (Package (0x08)
                        {
                            "built-in",
                            Buffer (One)
                            {
                                 0x00                                           
                            },

                            "layout-id",
                            Buffer (0x04)
                            {
                                 0x0D, 0x00, 0x00, 0x00                         
                            },

…

And make sure there's nothing in Device > Audio > Inject in the config.plist.

 

 

Where can i find this????? 

 

If you have also patch Radeon 5450 in DSDT, so remove the patch

config.plist looks like this

 

<key>FakeID</key>

<dict>
<key>ATI</key>
<string>0x68E01002</string>
 
 
Graphics 
 
<key>Graphics</key>
<dict>
<key>ATI</key>
<true/>

ACPI & Devices as shown in screenshots.

 

PS : Do not Inject ATI when using this!

I always used Inject ATI with 5450 Fake ID clover

 

Needs to disable patch ATI 5450 DSDT

I have no permission to upload this kind.

 

I upload to dropbox

 

https://www.dropbox.com/sh/scwh83tezyy1usf/AAC0yIGSMW5s4caaTZdDPWxVa?dl=0

Ok try this config.plist

NO DSDT

If the graphics card works with this config, 
you can test the Generic DSDT in the first post  B)

config.plist.zip

Nope... It takes a loop with restart. When i see the apple logo it restart.

 

If i delete the DSDT file it boot normaly but with 1280x1024 not Full HD

May be you need to change the Graphics card, some ATI Radeon HD 5450 not working  correctly

I suggestion to you the Geforce GT 710 Gigabyte 2 Gig  working OOB Sierra and High Sierra

No DSDT patch
