Developed a multi-monitor display device selection user experience enhancement for the multitheftauto/mtasa-blue repository, focusing on reducing setup friction for advanced users with complex hardware configurations. The work involved designing and implementing a dedicated device selection logic module in C++ and integrating it with the game’s initialization process. Adjustments were made to the selection dialog to improve taskbar behavior, ensuring smoother onboarding and greater reliability during startup. Leveraging skills in C++ development, reverse engineering, and the Windows API, the developer addressed user interface alignment with initialization flow and validated targeted fixes to improve usability for multi-monitor setups without introducing new bugs.
