NEC PA322UHD: Connectivity
Related: color space and gamut, computer display, color management
The 2013 Mac Pro has no trouble driving both the PA322UHD and a PA301W. No adjustments had to be made: connect the cable, boot up, job done, no issues whatsoever.
Various aspects of OS X are erroneous and this is not unique to the PA322UHD. For example,when the display scaling is set to 1920 X 1080, the System Profile shows that resolution instead of its true 3840 X 2160 resolution. Regardless, the display is of course 3840 X 2160, and it syncs up at 60 Hz at that resolution.
