Im using a laptop and would like to run Hearthstone on a secondary monitor. The trouble is that fullscreen mode only works on primary monitor and windowed mode doesnt fit the screen.
Small fix:
1 - open Hearthstone
2 - untick fullscreen in options
3 - move game window to secondary monitor
4 - open taskmanager
5 - rightclick "Hearthstone" - select Maximized.
