What?! Suddenly low resolution on display with my MacBook Pro (Retina, 15-inch, Late 2013)
What is happening here? I'm working with my MacBookPro Retina 15" with an external 30" screen. But suddenly now when using is without my external screen, the resolution of my dear MacBook Pro looks så LOW in resolution?! Please look at the enclosed images of screenshots to see what it looks like? I do hope you know what I can do. It's from late 2013, and I'm very happy with it otherwise. Please help!
