Sounds like another MSI laptop with issues: viewtopic.php?f=12&t=15711
We have some reports on the forums that the Windows 10 2018 spring update and the nvidia 397.31 drivers can solve this issue.
If that doesn't work for you, you can try to disable Optimus to work around this issue..
You should be able to do this in your BIOS.
If your bios doesn't support disabling Optimus, you could try our other workaround:
connect your external display, make it primary in windows,
start Resolume, and move the Resolume window to your laptop's screen.
You should be able to use Resolume now fine.
What you also could try would be to revert the nvidia driver to the latest from the 37x.xx series available for your card. We have some reports about it solving the issue.
You could also try to update your GPU drivers to the latest versions.
Or could try to disable the integrated GPU in the device manager.
Or Install windows 7 instead of windows 10 on this machine.
