P4320Q, split 4 screen replicating from top left for all sub windows
I bought the P4320Q and connected to the Lenovo X1 Carbon laptop running Windows 10. It was working fine for 6 months. All of the sudden for the past it does not send output different subwindows, for eg if a output extreme left top left windows, the same image gets replicated all other screens. How many splits I create in top left, it's been replicated on all screens.
I did uninstall all drivers (Nvidia, Intel, Dell) and DDM and did update the bios, reinstall drivers graphic card, Dell drivers, DDM, rebooted and even did uninstall and rebooted and installed the drivers still the same issue.
I am able to use extended monitor as windows basic extension but sub window are duplicating from top left corner screen. Support could not troubleshoot.
SR#
Support send back with different monitor and still no help. I also changed the laptop with different OS Windows 8 .1 and HP and no help, same issue.
I have the screenshot in case.
In support case the screenshot are attached. I would really appreciate some help.
Thanks

To begin with, forget about the Easy Arrange feature in DDM. It pertains to the Microsoft Windows desktop, not the U4320 PBP windows.
So: you have the U4320 PBP feature enabled with a quad split, but it looks like you have chosen to assign each window to the exact same input: HDMI2. So they all show *exactly* the same thing. That is as it should be.
If you want each PBP window (main + 3 subs) to be independent you must assign each window to a different input: e.g., main window to HDMI2, sub1 to DP, sub2 to DP2, sub3 to HDMI1. Put another way, to be independent, each PBP window must be linked/feed by a different cable and will appear as independent displays in Windows Display properties.
