Q: OSX Yosemite 2nd monitor issue after upgrade
MacBook Pro (Retina, Mid 2012)
NVIDIA GeForce GT 650M 1024 MB
OS X 10.10.3
This worked before the upgrade.
I've seen a few others that seem similar to mine, but this could be unique. I have a HDMI-->DVI-->Acer AL2216W adapter plugged into my MBP.
When it works:
1. After reboot
When it doesn't work:
1. After plugging into any other monitor and no reboot.
All other monitors using a straight HDMI or Thunderbolt adapter work fine. They work fine without reboots as well. Oddly the DVI monitor does appear to be "active" as I can drag windows into it, it just doesn't actually light up the screen. After a reboot, the monitor is active again. Once I plug into the TV, or an Apple Display, it stops working until another reboot.
Also, during reboots, I get a message that my computer shut down unexpectedly, which isn't true as I initiated the reboot.
