Dell Optiplex 7470 UHD 630 Pink screen or Black screen

[Ahmed Ali Shah]

Hello sir,
I have Dell Optiplex 7470 All-In-One, with 9th gen Coffee lake refresh CPU. I have followed dortania's guide but my screen becomes black. Then I saw that adding boot arg -igfxmod=pikera will solve it but no chance. Then I tried hackintool, it resloves the problem of graphic accellerattion but screen is Pink. I have also visited these sites

but still no results. Sometimes it goes black screen and sometimes Pink. Please help me resolve this issue. Thanks

@Ahmed Ali Shah Your AIO has HDMI connector for the built-in display. You'll need to change the con2 from 00040000 to 00080000 and the display should be normal.

Kindly mention exactly what to write in busid, type...etc. Is that 00080000 is a busid?
