XPS 15 9500, U4919DW max resolution 3840x1080?

I have a problem connecting my new XPS 15 9500 to my U4919DW. The max resolution I can get is 3840x1080. Previously, I had the XPS 13 9370 connected with just one USB Type-C cable and everything was fine. With the new XPS 15 9500, there is no way to get full resolution. I have even bought the docking station WD19TB connected via DisplayPort but same result: no more than 3840x1080.

Any solution

* Remove the WD19TB dock for now

* Turn all three off

* Connect the power adapter to a power source and to the XPS 15 9500 Thunderbolt 3 (USB Type-C) port with Power Delivery

* Connect the U4919DW USB Type-C Cable to the other XPS 15 9500 left side Thunderbolt 3 (USB Type-C) port. Connect the other end to the U4919DW USB Type-C in port

* Turn the U4919DW on, then turn the XPS 15 9500 on with lid open

* Once into Windows 10, open Display Settings and extend to the U4919DW, then check the supported resolutions

Same result:3840 x 1080 (recommended)

And it's the max resolution available

Since the U4919DW works at 5K 5120x1440 60Hz via USB Type-C on the other Dell laptop, the fault here is with the new XPS 15 9500. What options do you see in the Nvidia control panel for resolutions?

@sky.net  In addition to my reply above, since you've got an XPS 15 9500 in front of you, would you mind checking something I asked about in this thread and posting your findings there?  I'm very curious to know which GPU the USB-C/TB3 ports on that system are wired to, and perhaps if the non-Thunderbolt port on the right might be wired differently from the TB3 ports on the left.  All the test requires is to connect a display to each USB-C/TB3 port one at a time and check NVIDIA Control Panel to see which GPU it reports has control of the display while connected to each port.  Thanks very much in advance if you're willing to do this!

@sky.net  Take a look at my post marked as the answer in this thread.  It seems that 5120x1440 resolution support was broken in a somewhat recent Intel Graphics driver update, and chances are that the display outputs in that system are wired to the Intel GPU.  I linked to an Intel forums thread about this.  Rolling back to an earlier release resolved it for the person I was helping there.  I would have hoped that by now Intel would have rolled out a newer driver that resolved that bug, but perhaps not.

I had had found the solution before your reply. Basically instead using the Intel video drivers from Dell website it's enough using the most updated drivers from Intel website
