Photoshop CC 2014: Display Scaling Broken on 4K Displays (and Retina MacBook Pro)
See my review of the NEC PA 322UHD.
I’ve encountered a troublesome and erratically problematic bug: Photoshop CC 2014 Actual Pixels is not so. That is actual pixels (100%) might be drawn at 4:3 or 1:2 or something else. This is independent of display scaling mode.
