Re: P2715Q, Refresh rate only 30Hz at 4K

 

* MST is set to Off
* You only have the P2715Q connected to the Precision T7500 video cards. The other three monitors are disconnected from the Precision T7500

* You tested both Quadro K4000 DP out ports?
Quadro K4000 DP1 out port --> P2715Q DP to mDP cable --> P2715Q mDP in port
Quadro K4000 DP2 out port --> P2715Q DP to mDP cable --> P2715Q mDP in port

* You then powered off and tested the Quadro K600 DP out port?
Quadro K600 DP out port --> P2715Q DP to mDP cable --> P2715Q mDP in port
