I have a new PC with a high resolution screen and want to manually configure the size of the windowed MP1 resolution. By default it's set to 1938x1090 and I'd like to change it to 2560x1440. I've checked the MP Configuration in the Startup/Resume Settings but all I can seem to do there is set it to fullscreen or not. In MP1 I tried Settings->GUI->Screen->UI Calibration but that did not work either.
