bummer.. I was looking into Radut's fork, but not sure if that is the correct Driver. but I will keep digging there. Thank you,
Radut's may be even newer than the bpedman_merge branch (I may be forked from it).

I have no ALPS hardware, so I'm not tracking it...

yes my screen is 1080 that's why there should be no issues with it ..

the problem that every thing works perfect and screen resolution is 1080 without any problem .. all this till i press apple .. sleep
then after waking the lap again, the screen will have alot of artifacts and flickering and this leads to slowness in the system
but then i figured that the sytem itself isn't slowing because when i connect hdmi i can see that every thing is very smooth on the tv screen while it's very slow on the internal screen and hazzy with alot of flickering

then also i figured out that i can replicae the same problem by just changing resolution in display tab in settings
that's why i thought that the internal screen edid got messed somehow and screen resolution got changed after waking from sleep

and also my previous y5070 with exactly the same specs wasn't have any problem like this

and the only difference between the 2 laptops that the older one was recognized as 15.6 screen 1080 in apple..display tab while the new lap showing as 15.5 1080
and i think that screen info is being read from edid so if this one has messed edid, thats's why it shows as 15.5 not 15.6 as the older one

hope it's clear and hope if someone gave me his edid to compare it to my one and also look at apple..display and telling me if it's 15.5 or 15.6
and i'm not talking about the one in apple..overview which showing as macbook pro 15inch .. i knew that this one is related to smbios
i need the one in the tab just beside it

thanks for your patience

and the only fix to get my internal screen working perfect again is by restart
and my internal screen is made by samsung

my fear that windows 10 is the cause of my edid corruption as alot of alienware laptops have broken screens after windows 10 although i got 8.1 back now
here is link
http://forum.notebookreview.com/threads/windows-10-nvidia-whql-drivers-are-killing-alienware-and-clevo-lcd-panels.779449/
that's why maybe something changed making my screen can't be read as its original specs
Mido.fayad Hello, I have exactly the same problem as you. You got to find the solution?

Could configure the gtx 860m as if it were connected by thunderbolt
Or set up for the computer to think it is a gt750 or any compatible? sorry for my english and tanks.

I even had my bios patched and lowered the DVT value to 128. My resolution is all screwed up.... HELP!!!! Can someone upload their final EFI folder so I can compare to mine. PLEASE! Any help is appreciated. By the way I'm running Sierra.

Hello
I have problem with my laptop y50-70 i7-4720hq hd4600, gtx960m and full hd ips panel 1920x1080 - mac os x EL Capitan.
I installed the system according to the guide:

Https://www.tonymacx86.com/threads/guide-lenovo-y50-y70-uhd-or-1080p-using-clover-uefi.165188/

Great thanks to RehabMan for this tutorial

My problem is as follows:
After loading the system the screen gets black and sometimes the screen flashes but most of the time it's black.
On the external HDMI monitor everything works fine,

I have a full HD IPS: Samsung LTN156HL07401

When I repladec lcd panel in my laptop for testing from y50-70 full hd without IPS: AUO Optronics B156HTN03.6 everything works fine.

The problem is that on my IPS panel is a black screen

I have an EDID for my Samsung IPS but unfortunately I can not implement it for Mac OS X

In the attachment I am sending EDID dumped on windows from my samsung ips panel and my config.plist files.

Will anyone help run the Samsung IPS?

Read guide, post #1, "Problem Reporting" (use HDMI if necessary to collect the required files).

config.plist/Graphics/EDID/Inject=true
config.plist/Graphics/EDID/EDID=<EDID data>
(use a plist editor)

But first we should check whether Clover can detect your EDID (that's why I need ioreg... to extract Clover bootlog)
