A comprehensive Windows application for setting custom monitor resolutions with safety features and ease of use. Built specifically to solve real-world multi-monitor alignment issues.
I created this application because I needed to tweak my Surface Book 2 to support better alignment with my external monitor. The default Windows apps and third-party tools were either too complex, unsafe, or simply didn't work reliably for this task. This tool was built out of necessity and I hope it helps others facing similar multi-monitor challenges.
