P2715Q, Refresh rate only 30Hz at 4K
I have a Dell Precision T7500 with an Nvidia Quadro 4000 and Nvidia Quadro 600 graphics card running four monitors.
The Quadro 600 runs two Dell E228WFP monitors at 1680 x 1050 (native) (60 Hz refresh rate).
The Quadro 4000 runs a Dell U2713HM at 2560 x 1440 (native) (60 Hz refresh rate) and a Dell P2715Q at 3840 x 2160 (refresh rate of only 30Hz). There is no option for 60Hz or "native" like the other monitors. Both monitors are each connected to the Quadro 4000 by their own display port cable. I can get 60Hz refresh rate if I drop down to a 2560 x 1440 resolution but that defeats the purpose of the 4K monitor.
Also, I get ghosting when I drag menus from Revit 2018 across the screens, which is quite annoying. Doesn't happen with other programs.
I had a Dell U2213HM at 1920 x 1080 (native) (60Hz) before replacing it with the P2715Q and had no problems with the graphics.
OS - Windows 10.
Any help would be most appreciated.
