Yeah, I realized it after I made my post. Thanks for the tip, I will definitely check in here before I do any more major updates. I did however realise my BIOS vas 1.15.3, so it haden't updated to the latest version wich seem to give the most trouble. But downgrading BIOS to 1.14.4 helped my issue, after the downgrade the video output works as it should. Thanks for your answer!
Hi!   I did a bunch of driver updates the other day and after that video output for the USB-C port have stopped working, I connect to a docking station, keyboard and mouse works correctly but i get no video output, I only get a message that says "Display connection might be limited". I have tried both at home and at work with different docking stations that have previously worked and it's the same problem, I have tried to update the thunderbolt drivers but it's still the same problem. The drivers I initially updated included graphic card drivers and BIOS drivers, I made the driver updates through SupportAssistant.   Does anyone have any idea of any setting that could cause this? Or is it that the drivers from Dell is causing this issue?   Sincerely Joel
