Dell support provided a fix with 2 driver upgrades, which were incidentally not indicated when I tried manually to check the driver staus on my device manager. Good service from Dell support, but should this be happening on a relatively new machine?
I have the same problem, my Dell XPS 9570 laptop is not detecting HP external monitor via HDMI cable using Windows 10. Does anyone have a fix for this?
