Remarks: 1)Pls make sure the DP port of your PC or laptop is of DP1.2 and above. 2)pls make sure that the DP soure has already implemented full support for MST. 3)In spite of that you can connect AMD Infinity compatible active DP adapter to the DP out of the cable, DP direct connections are recommended for reliability and compatibility. 4)Vesa certified Displayport 1.2 or 1.4 cable is needed(most screen flickering or vidoe on/off are caused by non-qualified Displayport cable). 5)Mac. OS are not supported for MST function. 6)this Displayport MST hub does not work with any dock. 7)Bandwidth:Refer to the bandwidth specs of the video source supplier to make sure the total bandwidth of each display does not cecced 100%. 8)Number of Displays:MST function can not increase the number of displays a video card supports.Regardless of the number of video outputs your video card comes, each video card has a limited number of display it can support.(Most AMD and Nvidia video cards supports no more than 4 dispalys while intel supports no more than 3 displays.) 9)AMD RX560/570 and Radeon 7220 series are tested to support no more than 2 displays.
