I suggest to :
1.Make sure Windows is up to date, run Windows Update.
2.Check MSI Home Support, to view the latest laptop drivers. these drivers are customized by MSI to specifically work for your model. http://us.msi.com/support
3.Try downloading from Intel®'s web site https://downloadcenter.intel.com/ the latest, graphics drivers https://downloadcenter.intel.com/product/81496/Intel-HD-Graphics-4600-for-4th-Generation-Intel-Core-Processors , these are generic drivers for the Intel® HD Graphics 4600.
I spoke with the engineering team on this and received an explanation as to why this is no longer working in Windows 10.
Microsoft changed the way we can implement this in Windows 10. The LFP [Local Flat Panel - aka laptop display] is no longer included in collage mode options starting with Windows 10 and this is expected behavior per the new implementation moving forward. Only EFP's [External Flat Panels] will be available choices in collage mode options.
