monitor recognised at first & all working OK for a couple of hours. Then external went black & flipped a couple of times between dell & monitor. Now no monitor recognised.
All Dell updates completed.
Neither HDMI nor DP cables work
Monitor works with basic unpowered usb-c hub with hdmi output.
What’s going on? Thought I’d checked all possible compatibility issues…
