I'm trying to start Monogame development on my MacBook Pro 13inch 2017 and I see weird problem. I'm using Monogame 3.6 DesktopGL project and my Retina display resolution is 2560x1600 pixels:
But when I set:
graphics.PreferredBackBufferWidth = 1440;
graphics.PreferredBackBufferHeight = 900;
Then window perfectly fills whole screen as you see on screenshot bellow:
And that is weird to me because if my screen resolution is 2560x1600 how can window with resolution 1440x900 fill whole screen?
