Keep 3 monitor setup permanent

I use 3 mionitors, but every time I go from main menu to fly or vice versa, or go from pancake mode to VR or back, the side screens moved back to the middle monitor, i need to go into menu to set them up again which is extremely annoying! Any suggestions for keeping those screens where they are permanently? Thanks.

Are you using Nvidia?. If so, when you have placed them in Display Settings, make sure you click Apply.
