Mar 19, 2014 7:49 AM in response to athomas1by amaga,yes, I can confirm that after replace files the second monitor is back.
1. Use TimeMachine to copy all AMD* files from /System/Library/Extensions/ to temporal folder.
If you need 10.9.2 AMD files, I've shared via dropbox
2. Use "Kext Utility" app to import old files (from TimeMachine). click here to download
3. Restart computer.

Mar 19, 2014 7:58 AM in response to nAPPster84by joelstewart,I am having a similar issue after upgrading to 10.9.2. I am interesting in downgrading back to 10.9.1. I do have a Time Machine backup. Can you explain how you downgrade to 10.9.1? Is it as simple as restoring the Library folder back to before the 10.9.2 update?

Mar 19, 2014 9:55 AM in response to amagaby dankohn,amaga, thank you so much for the files and your solution. What a relief to have mu second monitor working again.
I'll just mention that I couldn't get kext utility to work, but instead needed to use Kext Wizard.

Mar 19, 2014 10:02 AM in response to tbartoncvby epistemic,Also, out of curiosity, what was the 5th kext you loaded? I'm only seeing these 4 from your screenshot:
- AMD7000Controller.kext
- AMDFrameBuffer.kext
- AMDRadeonX4000.kext
- AMDSupport.kext
I tried replacing those 4 with the version (1.16.39) I extracted from apple's OSX 10.9.1 mac pro updater PKG but it simply caused osx to fail to advance to the login screen (instead it showed me some noisy junk framebuffer). Bummer!
Also, amaga's files seem to be version 1.14.21, which I'm hesitant to try since my other attempt failed.

Mar 19, 2014 8:13 PM in response to amagaby leifdalan,Thank you so much amaga! I also followed up with Apple's bug tracking system with obvious outcome. Now I can use my monitor that had always worked.
Much appreciated!

Mar 20, 2014 1:08 AM in response to leifdalanby PawelDysput,Hi Guys.
MBP 8.1 and displayPort -> VGA doesn't work, DVI does – but unfortunately I don't have display with this input. So I'm trying to do everthing including PRAM & SMC reset, but no results.
The last option is amaga solution. I don't have any backups so i wanna ask you guys, can anyone can share file for intel graphic extensions.
In extension directory i have 4 file which was changed after update to 10.9.2.
- IOGraphicsFamily.kext
- IONDRVSupport.kext
- IOPCIFamily.kext
- System.kext
Thanks.

Mar 20, 2014 1:29 PM in response to athomas1by juliustayl,amaga!! thank you so much. That worked completely for me! You are a lifesaver my friend. thanks again.
If anyone else is having similar issues I suggest following amagas instructions using the drivers he uploaded to dropbox and the kext utility.

Mar 24, 2014 3:28 AM in response to William Kucharskiby Paul Krawitz,Ha!
Read the thread, and this simple fix (re-selecting my previous display profile in System Preferences/Display/Color/Display Profile) was my problem on an iMac with a flickering display.
No SMC or NVRAM/PRAM Reset necessary here.
