2nd monitor not in focus in lightroom

[jlykins]

I have dual monitors (dual 24inch samsungs). I've been using dual monitors for months now. All of the sudden when I double click on an image to bring it up full sized in the second monitor, it looks out of focus. I thought my shots were out of focus today when I pulled them up from last weekends wedding. They look beautiful in PS so it's definately something in Lightroom. Can anyone help me? They look fine in thumbnail view it's just when they come up full sized.
