    Any other nMP owners having issues with dual monitors? I noticed this since the beginning, but it seems to have gotten worse ever since updating to the 10.9.3 beta.

    Basically one of my monitors turns on, but the other does not — causing all windows to be gathered onto one monitor, which can become quite annoying after having to do it a few times each day. And it always seems to happen once the monitors go to sleep. The only fix, besides restarting my Mac Pro, is having to turn off and back on the monitors.

    By the way, I'm using dual ASUS PB278Q's. Amazing monitors! It's just a little weird that this is happening. Sounds like a Mavericks issue... Thoughts?

    I'm on 10.9.2 and see that as well.

    Even on rebooting the computer I have to do the magic order or I end up with a corrupted image on the screen and the mac locked up or one monitor just blinks and the other screen flashes trying to make a connection.
