I connected an LG 27UD88-W to my 2012 15" Macbook Pro via DisplayPort. However, it does not seem to connect at the expected 60Hz for the 2560x1440 resolution, but instead it shows 59Hz.
One could argue "oh well, you won't notice that 1Hz" but that is not the point. I like to understand things.
Does anyone have an explanation for this?
