I pull my hair out with this and wonder if anyone can help.
I have a MacBook Pro (Retina, 13 inch, late 2013) and a 4K monitor ACER CB280HK.
I want 2K (2048 × 1080) resolution on my screen, but the only options are these.
I've tried using SwitchResX to get 2048 × 1080, but it's really notched.
I don't understand the specifications that say I can use;
I'm connected via thunderbolt ( Mini display port)
Does anyone have any ideas why this might not work? My Windows machine shows 2K just fine on this screen!
