Mini-DP to HDMI resolution output on 2014 Mac Mini

[Suture]

On the 2014 Mac Mini, if I used a DP-to-HDMI adapter to connect to my display via HDMI, am I still limited to 1080P resolution, or would it allow 1440P?

The maximum resolution for Mini-DisplayPort adapters is 1920x1200 except for the Dual-Link DVI adapter. For resolutions higher than that over HDMI, you should use the built in HDMI port.

Thanks -- but I was finding things indicating that the HDMI only supports up to 1080P. Does it do 1440P? My monitor has 1 DP, 1 HDMI, and 1 DVI. The DP has to be used for my PC, but am trying to get a Mac Mini hooked up at 1440P also.
[doublepost=1475714199][/doublepost]I should add, specifically, this is one of the things from Apple's tech info:

HDMI video output

• Support for 1080p resolution at up to 60Hz
• Support for 3840-by-2160 resolution at 30Hz
• Support for 4096-by-2160 resolution at 24Hz

It says 1080P at up to 60Hz, and then specifies the other resolutions at specific intervals. So I'm wondering if 2560x1440 is even an option at all, and if so, at what refresh rate.
