I am hoping any nMP owners could give feedback as to whether the SwitchResX software that creates custom HiDpi output resolutions works with the nMP w/ 27" Thuderbolt Display. I'd be interested if a custom 1920x1080 HiDPI resolution could be created as it's what I have running on my late 2012 27" iMac. It seems it works with internal monitors but doesn't always work with external monitors.
