Hello all, I have a MacBook Air 13" from Early 2014. The supported resolution for external displays goes up to 2560x1600. I connected my new monitor to it, which is a new ultra-wide LG with 2560x1080 resolution. I made sure to buy a Mini Display port to HDMI (4K) adapter that supports these high resolutions. So everything should work correctly. Yet, I cannot set my new display to any resolution above1920x1080 . How do I proceed? I feel like I have tried anything, even bought another expensive Mini DP - HDMI 4K adapter, still not getting the desired resolution. Any thoughts are welcome.
