Eh? I have provided the SYSTEM INFO panel, which clearly shows they are all running at full native resolutions.
Like I said in my previous post, system report may be deceiving you. You can read more about it below. The Mac Pro is reporting 5K as well, but we all know that's impossible.

Download SwitchResX, which will give you the resolution AND the refresh rate.
