Wyse C90LEW screen auto resize

Greetings,

I am planning to roll out 220 new terminals and I have one small problem. Users have different screen res requirements, not much of a problem you may think! Well the C90LEW's insist on changing the screen res once they are moved or lost power. It's driving me nuts. 

Is there a way to sop this auto config?

Thanks
