Is the P2815Q USB upstream cable connected from the P2815Q USB upstream port and the other end connected to the XPS 8900 rear blue USB port? I am not sure what version of DDM was in the CD, but the website list two versions =
First, my bad the model is P2715Q and not P2815Q. To answer your question the usb is not hooked up. This excerpt is from both of the driver pages - "DDC/CI is not supported on USB connection". I am also running win10 pro... The supported versions only go up to win 8.1.
That is confusing to most. That message is for users who are using USB as their video source through the DisplayLink software or a USB video adapter. User who connect via DP, mDP, HDMI, DVI should have DDC/CI enabled in the monitor OSD (On Screen Display) =
DP 1.2 or MST should be Disabled or Off =
If still no go, connect the USB cable to both and retest.
The DDM diagnostic log can sometimes pinpoint problems like this. While holding down the SHIFT key, right-click on the DDM system tray icon and and then select "Save diagnostic report" from the popup menu and post the content.
In case you didn't see this, from the DDM read me:
Troubleshooting ----------------------------------------------- If DDM is unable to detect and/or communicate with a supported Dell monitor: - make sure you have the correct and latest display driver from the graphics vendor (AMD, Intel, NVidia) - check the monitor OSD to ensure DDC/CI is enabled - remove any docking stations or cable extenders or converters between the monitor and the graphics port - with first generation DP 1.2 monitors, it may be necessary to disable DP 1.2 using the monitor OSD - virtual and wireless displays do not support DDC/CI
