Hi all, We have found a workaround, for the display not usable. I give it here for people like me who were stuck... with dell.
Since I cannot comment my post #24, here a summary: Step to reproduce: Plug HDMI cable 4k ready, of course connected to 4k screen. Actual result: Purpul screen (default color of my background) on both screen... To have any things displayed I need to use CTRL + ALT + F1. Using "Screen Mode" key (i.e. F8) we were able to have display properly set. Hope this helps...
