Change the compatibility properties, as follows:. Right-click or press and hold the application's icon, and then select Open file location.A folder that contains the start menu shortcut for the application will open. On the Start screen, type the name of the game application. You can usually search for the file by using Windows 8.1 search, as follows: To make these configurations, locate the game's executable binary, and then change the compatibility properties of that file. This is because a change in the global desktop DPI scaling settings affects other desktop applications and may cause content to be displayed too small to be usable. This should be done only for specific applications. We recommend that you manually configure games to be exempt from output and input high-DPI scaling. The effect can be seen either in the position of the pointer or the location at which you can interact with on-screen content. In these cases, you may experience mouse input that is either consistently larger or consistently smaller than what is reflected on the screen. But this detection fails in some games and upgrade scenarios. Windows detects many full-screen games and exempts them from both input and output high-DPI scaling on successive starts. 
However, games frequently use one or both configurations. Most Windows desktop applications don't use full-screen mode or raw input.
Games that use "raw mouse input" in windowed mode and bypass the input scaling of Windows (only output is scaled). Games that run in full-screen mode and bypass the output scaling of Windows (only input is scaled). However, there are two scenarios in which scaling can be mismatched: Scaling both input and output guarantees a consistent experience for the application user. It also scales mouse, pen, and touch input that is sent to those applications. Windows 8.1 supports bitmap scaling of desktop application content for applications that don't natively support high-DPI displays. This article describes how to work around an issue in which mouse input in some games is incorrectly scaled on high-DPI devices.Īpplies to: Windows 8.1 Original KB number: 2907016 Introduction Mouse input in some games is incorrectly scaled on high-DPI devices
