multi monitor configuration lost if monitors switched off

We are using multi monitor configuration with 2 monitors 1920x1080 resolution each. The zenon6.ini parameters are set RT_CXMAINFRAME=3839, RT_CYMAINFRAME 1079. On each monitor are shown several frames with buttons, alarm head and plant pictures. After runtime start anything is fine. Now our problem: after switching off the power of the monitors (monitors off over weekend, runtime still continues) all frames and pictures from second monitor are on the first (main) monitor in the background. All attempts to solve this in runtime doesn't work. The only way to get the frames and pictures back to the second monitor is to shutdown and restart the runtime. But this need long time (redundant system) and is not usable for our customer. Do anybody have a better solution for this?
Many thanks in advance!
