[solved] x220 dvi fullhd mod

[icylynx]

Hi, have lenovo thinkpad x220 laptop with i5 and hd3000, running fullhd mod (LG Display LP125WF2-SPB4 via displayport 2 custom connector). Windows and linux runs OK. In Sierra, the is no picture on internal display, when i am adding external monitor via displayport connector i see the picture on internal monitor, but the colors are wrong. I tried: injecting edid via clover, add RehabMan fixes for HD3000 with 1600x900 (DualLink, etc.) but still no luck. Any thoughts what can be done next?

In post #1 you stated the internal monitor was not working.
Your ioreg shows EDID detected.
And you have a photo showing the internal monitor.
Afraid you'll need to explain more clearly... and provide data that represents the problem scenario...
Also, no files in ACPI/origin provided.
Please re-create ACPI/origin and press F4 as per "Problem Reporting".

I am updated Sierra and now it works. but with wrong colors. Clover boot screen is visible, apple logo with progress bar and on login screen internal lcd messes up colors. It is not internal lcd actually, the panel connected via displayport 2 on dock with soldering. So, technically there is no physical internal lcd. internal lcd emulated by extension card, which placed on displayport 2 on dock connector and having displayport wire to the physical internal lcd fullhd panel. i think that this is solely Sierra's graphical driver issue. Because in linux and windows this setup works fine. One difference in those OSes that they detects not only displayport 2 on dock lcd but also dummy display in mirror mode which is physically soldered extention mod card connected to lvds.

So, the question is - is it possible in Sierra detect that dummy card in lvds slot in addition to this detected fullhd lcd, because i do not see it in ioreg output.

It is because you deleted ACPI/origin.
