    I have a new LG 34UM95 that has been working flawlessly for a few weeks now. My wife was working on a usb device for our son and I came home to a white screen that wouldn't disappear until a hard reboot.

    Now, the rMBP won't see the monitor until I power down the monitor (pull plug) and start it back up.

    If I disconnect the TB cable from the rMBP to the monitor the computer tells me I incorrectly ejected a disc (the hard drive connected to the monitor) but it won't connect visually.

    I have reset the PRAM and the SMC and repaired the permissions. What else could be causing this.

    Computer is also taking a long time to restart. Much longer than it used to.

    You need to provide more information.

    What gen RMBP? What OS version? You left out the most important details.
