IceProgrammer Posted August 1, 2013 Share Posted August 1, 2013 Hello every one I have problem making my HD 4000 working properly and i need someone to help me figure it out. I really searched a lot and tested many many different solutions with no success. Here is my situation : 1) If i use 166003 -> i can see only half of my desktop! I believe it can be fixed using Dual-Link patch but i used this patch and it make no difference! i used "AAPL01,DualLink" and also "AAPL00,DualLink" (don't know the difference though) but nothing changed 2)if i use 01660004 -> I get full picture, (also tinted and dark screen) but the problem is that several green and red pixels appear on the screen and it doesnt work properly. I attached screen-shots of this mode. Personally i think 01660003 is the correct one, but i don't know how to make enable duallink or anything else that can give me a full picture. maybe duallink is not the cause of half picture screen? I really appreciate if someone can help me on this problem. Thanks Screen-shot 2 Link to comment Share on other sites More sharing options...

IceProgrammer Posted August 1, 2013 Author Share Posted August 1, 2013 Yes Artur, thank you for reply i tested these ids : 0,1,2,3,4,8,9,A,B all got black screen except 3 and 4 I also use correct EDID for monitor I don't have ability to test it with external Display myself, but we are about 4 or 5 guy with same laptop from different countries having this problem and they confirm they got correct picture and QE/CI enabled on VGA output. The strange thing is that a few person with same laptop model and same specs installed mac ML successfully. but we have this problem even with same CPU model and exactly same EDID on same laptop! i dont know its fixable or not and i am trying anything to get it working The black screens mean its absolutely wrong ig-platform-id?
