    Just updated to 10.12.4 on my 2013 6-core Mac Pro with D700s and 64 GB RAM. I have two 30" monitors. The resolution of one of the monitors, a Dell U3011 connected with displayport, is now being limited to 1080P max and not the native 2560 X 1600. Rebooted several times with no change. Never had this problem before. Any one else with this unacceptable problem?

    I assume you mean 10.12.4. Anyway, did you try hold down "option" key and then click "scale" in the system preference?

    Fixed it by deleting /Library/Preferences/com.apple.windowserver.plist then rebooting, then pressing the option key when toggling to scaled resolution in the display preferences of the control panel. The correct resolution was now an option. Looks like Apple does not even bother testing updates on the very old yet still new 2013 Mac Pro. Not impressed.

    My Mac Pro is acting slightly different.

    It sees my 27" 4K Samsung display as 61". It also detects that it is a retina display in the display settings. The default for the display is 1080P. I confirmed this by clicking on scaled and it goes straight to the far left on Largest Text. If I put it on the next one over to the right I get 2560x1440 which is easy to read for me. The far right option makes everything super small at 3840x2160.

    So it is working for me but for whatever reason they defaulted the display to 1080P which is just awful. It took me a few minutes this morning to figure out why my screen was pixilated and gross. LOL
