I just bought three 1440P monitors to replace three 1080p monitors. CloneBD is the only program which will now not move to another other than the main (middle) monitor. If about 1/4 of CloneBD goes to another screen it will automatically snap back to the main screen. AnyDVD nor any other program/file has this issue.
edit: I also replaced my GTX 1080 video card with a GTX 2080 Ti
