So i have 2 Screens. one smaller and one larger. i made the smaller one my "primary" screen and started LOL. then i took the patcher to the larger screen. after pressing play, the PVP.NET-Client was rendered to my Main Screen (the smaller, "primary") again. Again i moved him to the larger screen. when the game started, the Client was rendered to the smaller screen with the resolution of the bigger screen(!). someone has an idea on how to avoid this?
The placement of the launcher has no bearing on where the game will display. If you are playing in fullscreen mode it will default to your primary monitor. Some games have the options to set the monitor you are wanting to use, this is normally located under options > video.
