You won't be able to get 1440p through the "old" HDMI protocol that easily.

First of all, regardless of adapters, it cannot be 1440p @ 60Hz. Not enough bandwidth through HDMI 1.3 or lower to do so.
Some people connect DVI-D monitors through high quality cables/converters to limit interference, but use custom resolutions @ lower refresh rates (I think it is mandatory).

So, with this in mind, you probably need a HDMI -> DVI-D adapter + something like the post above for DVI-D -> DP / miniDP + custom settings.

I ordered the same, unless you are using an older apple LED, it doesn't work for the 2013 version as it doesn't support thunderbolt, if you read the description it says DisplayPort compilable only and the new Apple LED come with thunderbolt port only (no thunderbolt), i've also contacted the manufacture and confirmed this.

You're pretty much sunk. There isn't an HDMI -> DisplayPort adapter that supports full resolution.

See this:

Kinda expensive, and both adapters max out at 1920x1200.

Your best option is a USB3 -> DisplayPort adapter:

Also, it is running full 2560-1440 dual link HDMI, to mini display.
Wondering why did you go with ACD? the reason I was trying to get it work with PC was that i already own one for my macbook pro and I was trying to get it work with my new PC.

You can get a Samsung U28D590D with higher resolution for cheaper (it will be released next month) http://www.amazon.com/gp/product/B00IEZGWI2/ref=ox_sc_sfl_title_7?ie=UTF8&psc=1&smid=ATVPDKIKX0DER
