Hi TeKa_PL!
After the games launches, if you press SHIFT+WINDOWS KEY+One of the directional arrows, it will move the game onto another monitor. The arrow you would need to press would be dependant on the direction of the monitor. If you want the game on the monitor to the left of the one it starts on, you would press the left arrow.
Unfortunately it doesn't work. When I switch the game according to the instructions, unfortunately a white screen appears on the second monitor and the game is still displayed on the second monitor. I only see that in the white image I can choose the game options which are displayed on the second monitor anyway.
