I have a 15" mid-2014 MBP (NVIDIA GeForce GT 750M 2048 MB). It is currently running two external monitors, a 4k and an HD (1920 x 1080), both at 60 Hz refresh.

I'd like to know if it can instead run 4k + QHD (2560x1440 or 2560x1600), also at 60 Hz refresh.

Also, if it can run the QHD, can I connect it via HDMI, or would I need TB?

I'd prefer to hear from someone who is (or has tried to) actually run both a 4k and QHD on a 15" mid-2014 MBP w/ the above-listed graphics card.

You can only run a single monitor at 60hz over thunderbolt
