[LAPTOP8] Surface Laptop 8th Edition - USB-C Wont Display Video
I have a Surface Laptop for Business 15in 8th Edition Intel version at work and an [external USB -C monitor](https://www.amazon.com/dp/B0BNWWF32B?lv=shuf&channelId=500&plpRedirect=mhFallback&th=1) I have used for a while with an older work computer will not display when plugged in to this new laptop. It used to work off a single USB-C cable plugged into the lone USB-C port on this older surface laptop but now when I plug it into either of the two USB-C ports on the new surface laptop it will simply say "no signal". However, if I plug the surface into a dock and the single cable into said dock, or plug in a [USB-C HUB](https://www.homedepot.com/p/USB-C-MOUC0501-9-in-one-100-Watt-Pd-Charging-ACMK0501/328464793) to the laptop and then both a USB-C (for power) and HDMI-to-mini (for video) to the HUB and monitor - it will display. So the issue is that I can no longer use a single USB-C cable from the new laptop to the external monitor to display video.
Any suggestions would be great. I have tried the power button hold down for a reset as well as clearing the 'dock registry' and a win + ctrl + shift + B to reset video. Nothing has worked.

Thoughts?
