Plutonium

when I try to change my monitor in my t5 players configs it does work for like a split second when i start the game but as soon as the sound comes in, my screen just goes back to my main monitor instead of the one I play the game on, no settings reverted back in my configs for mp and zombies.
I have 3 screens my main one which the game defaults back to, my second one which the game does not want to run on and a 3rd one on which the game also runs. So I am kinda lost as to what I can do to get it to run on my second monitor. Can this be fixed?
