Hi, I need some help with this..... So I bought a 27" 1440p monitor (2560x1440). I also have a late 2013 rMBP. It is fully capable of outputting this resolution through hdmi and thunderbolt 2. However, the monitor does not have a displayport. So I have to use either dvi or hdmi in. Now the question is, I have a hdmi cable, and it works perfectly, 2560x1440 @ 60hz. But I also bought a mini dp to hdmi cable. It does not work. It only outputs 1080p as maximum. I cannot select anything higher. I assume it has something to do with hdmi specs or drivers? It was a no name cable. SO, I was wondering if anyone has successfully used a mdp to hdmi cable to output this resolution, and I just need to find a better cable/adapter. If it is impossible I shall stop trying now.
