Dell XPS 13 Touch Screen / Driver Issues

[terrymrowley]

I just purchased a Dell XPS 13 Touch with 4K screen resolution (3200x1800).

I had no issues with my previous computer using the exact same monitor setup, but now Displaylink is randomly unstable when attached to the XPS 13, for example:

- the two connected monitors stop working and only the laptop screen is active (sometimes the monitors will work again if I remove the USB plug from the laptop, sometimes they don't work until I do a hibernate or reboot)
- all the screens freeze but come back after I hibernate the computer
- the monitor resolutions change while the computer is on
- the two connected monitors stop working momentarily (all open windows move to the laptop) and then they come back on line (it's happened 3 or 4 times in a 5 minute period)

I'm running DL v 7.9.1336.0 and have the latest drivers for the monitors and the laptop.

Could it have something to do with the 4k screen of the XPS 13?
