Install Ventura on Dell Optiplex 7450 AIO

[alex4life61]

I'm pretty sure this Dell AIO uses LVDS. https://www.pcmag.com/encyclopedia/term/lvds

That adds another layer of complexity when trying to make the built in display work. Others have
attempted hackintoshing Dell branded AIOs. Do some searching of the forums to learn more.

BTW the purple display happened to me on catalina and i solved it by adding proper platform

no need for:
AppleALCU.kext
FakePCIID.kext
FakePCIID_Intel_HD_Graphics.kext
SATA-200-series-unsupported.kext

unless you have a laptop keyboard and laptop trackpad, then you can also remove all the:
Voodoo* kexts

all of these "Strings" should be in "Data" format

<key>PciRoot(0x0)/Pci(0x2,0x0)</key>
            <dict>
                <key>AAPL,ig-platform-id</key>
                <string>00001B59</string>
                <key>framebuffer-patch-enable</key>
                <string>01000000</string>
                <key>framebuffer-stolenmem</key>
                <string>00003001</string>
            </dict>
        </dict>

Have you tried - 00001259 for AAPL,ig-platform-id ?

Have you tried adding a line in Device Properties with - device-id 12590000.

And as @Feartech says, these values are "DATA".

(Back-up before testing, as usual).

also make sure in your BIOS that DVMT is set to 64MB or 128MB
