 &How to reproduce:
1. Open the attached project "displayTestNew.zip"
2. Build and Run the scene "SampleScene" on macOS
3. Observe the values under Main Display and Screen.currentResolution

Expected results: The values under Main Display match the ones under Screen.currentResolution

Reproducible with: 2019.4.39f1, 2020.3.34f1, 2021.3.2f1, 2022.1.1f1, 2022.2.0a13

Notes:

• Moving the Build window to an external monitor updates the values to the correct ones even after returning the window to the main one
