How to set screen resolution to 2560x1600?
I have a Retina MBP 13" late 2013. I noticed that when I plugged my extended HP 27f 4K monitor, I can no longer use the max screen resolution on my MBP which is 2560x1600. Even when I unplugged my extended monitor, I don't hav in my display preference the option to use 2560x1600.
Any thoughts? How can I set my resolution to 2560x1600 again?
