Hey guys,
I'm using X220, and just installed Mavericks following this thread http://forum.thinkpads.com/viewtopic.php?f=32&t=112210
After that, I tried to make VGA work.
Since I'm not familiar to Hackintosh, so just installed a modified AppleIntelSNBGraphicsFB.kext by KextBeast.
http://www.mediafire.com/download/6ui76 ... B.kext.zip
I downloaded several versions of it, now I couldn't be sure about from where did I download this file .
Mavericks did detect the external monitor with 1920x1200, but obviously it's outputting at a wrong resolution.

External Monitor

My external monitor resolution is 1920x1200, but the actual resolution it's outputting is 1600x1200
And the screen seems to be incorrect(cropped on left side), see the photo below

ps. this resolution works fine on Windows
Any ideas to fix this?

Re: VGA output problem
So finally I noticed the problem is due to the Mac OS itself. It can't support VGA output at high resolution, like 1920x1200.
I bought a DisplayPort-to-HDMI cable, and modified the AppleIntelSNBGraphicsFB.kext file according to http://forum.osxlatitude.com/index.php ... d3000-gpu/
and set value 02 05 00 00 00 08 00 00 06 00 00 for DisplayPort output. Now it works at 1920x1200 resolution.
