Thanks for your reply. I admit I didn't understand a lot of that thread
Here's my current EDID if it can help you to understand or to give me some more precise suggestions.. Thanks a lot

ioreg -lw0 -r -c "IODisplayConnect" -n "display0" -d 2 | grep IODisplayEDID
"IODisplayEDID" = <00ffffffffffff0006afed3800000000001a01049522137802bbf5945554902723505400000001010101010101010101010101010101e83580a0703818406c30aa0058c110000018f02380a0703818406c30aa0058c11000001800000000000000000000000000000000000000000002001048ff0f3c6e1e14216e202020009d>

Thanks, so do I have to find & replace in SSDT-ZBook-G2-Haswell.dsl like this ? :
FIND

_SB_PCI0RP05DGFX

REPLACE :

_SB_PCI0PEGPDGFX

What should i edit precisely for EH01 & EH02 ?

It is best that you implement the changes directly to the source files, then use build.sh, install_acpi.sh as per guide.

Read at the thread mentioned. You need to create a display override file with patched EDID.

Any chance someone could create a mini step-by-step guide for creating a display override file for those of us with EDID issues? Unfortunately, the information contained in the thread you linked is a bit high level for people like me.

I may do it at the point I run into a computer with the problem.

Where should I get the new/correct EDID?

Ok thanks, so i just need to edit SSDT-ZBook-G2-Haswell.dsl like this :

// SSDT for ZBook G2 (Haswell)

DefinitionBlock ("", "SSDT", 2, "hack", "zbg2h", 0)
{
    #include "SSDT-RMCF.asl"
    #include "SSDT-PluginType1.asl"
    #include "SSDT-PEGP_DGFX_RDSS.asl"
    #include "SSDT-HACK.asl"
    #include "include/layout17_HDEF.asl"
    #include "include/layout17_HDAU.asl"
    #include "include/standard_PS2K.asl"
    #include "SSDT-KEY87.asl"
    #include "SSDT-USB-ZBook-G2.asl"
    #include "SSDT-XHC.asl"
    #include "SSDT-BATT-G2.asl"
    #include "include/disable_EH01-EH02.asl"
}
//EOF

Then build.sh, install_acpi.sh ?

Yes.

The edits are just to the basic-params byte at offset 16. You have 0x95 there now. Suggestions are to change it to 0xa5 or 0xb5 (you will find those values if you read the thread carefully).

No thanks.
