Dell TB16 with Dell XPS 13 9350

Hi,

i have some issues with my Dell XPS 13 (9350) and Dell TB16. I connected a 4K Monitor on the MiniDP Port and another 1080P Monitor on the HDMI Connector. I get constant dropout of my 4K Monitor, like every 1-2h min. the screen goes black and after a few moment the video comes back. Updating everything to latest BIOS, TB Firmware, Video Drivers does not working. I tried to disable TB security in BIOS but this doesnt help either.

I tested my TB16 with another device, this time it is my company Lenovo P50. Everything works great with this device, no video dropouts, i tested this several ours.


So what is wrong with the Dell XPS13 and Thunderbolt?

Sorry for the long delay. No the 4K issue isnt fixed. I think the Dell XPS 13 hat to much trouble with very high bandwith needed for 4K. I had this issues with several USB-C to DP/HDMI Adapters using alternate mode.

WIth other Notebook Vendors this Dock works great (sigh)
