Pro Apps Codec update = loosing 2nd monitor

Upon restart, hold option. Do it right after the chime, before grey screen.

From there, you should be able to choose recovery disk.

Once booted to recovery, the first thing I would do is use disk utility and repair permissions.

Then reboot to normal.

If you are still having problems, reboot to recovery and reinstall. Make sure you have all of your data backed up before reinstall.

If none of that works, you have to download Mavs from AppStore.

Tried re installing the os from the recovery disk and same issue. Installed Mavs on an old system disk that had Snow Leopard on it. Same issue. Tried to update the cuda driver from 4.2.10 from within the pref pane and the update fails.

Need to get running for a color job that starts on Monday. Perhaps I need to build up a new SSD from the ground up?!

If you have this issue in two OSes, that port may be dead.

However when I boot the same machine under 10.8.5 BOTH monitors are working with the GTX 680 card.

After re formatting a drive, installing 10.9.4, downloading the cuda web driver, repairing permissions, restarting a number of times, I still have the same issue of only one monitor operational under 10.9.4. going into the preferences and selecting the cuda updater it says that there is a newer version available, once it try to install the new driver it fails at 20% each time. No difference with web driver or OSX driver.

So for now once again all FCPX work will have to be done on one monitor. Just went through this same thing a few months ago. All of this does not feel very pro to me. Perhaps I just need to purchase the $6000 dongle.

Hopefully nVidia will have the latest driver available for web download sometime soon.

Update: Following the instructions about halfway down this page from “therandyzone”

deleting the kext files downloading the other ones in the link and installing them with Kext Utility has worked for me. I now have my second monitor back on my GTX680 running under 10.9.4. Very happy 🙂
