Hey,

I have a GTX 750TI and a Samsung SyncMaster FX2490HD, running Windows 10. When trying to switch to fullscreen ingame, it states that is has switched but it acutally hasn't. I still can drag the mouse out of my first screen.
So I tried the following things:
NVIDIA control panel, set scaling to no scaling -> doesn't help
NVIDIA control panel, set scaling to fullscreen -> doesn't help
Delete the option.ini file to see if game starts in fullscreen -> doesn't
Set the DisplayModeType=2 and make the file read only -> doesn't help
Delete DisplayModeType entirely -> doesn't help
Switch off second screen -> doesn't help

Is there anything else I can do?

Thanks a lot

Best wishes
