Cannot connect 4k display to Spectre x360

All~

 

A fantastic update to my problem. The theory from the last customer service rep I spoke with on the phone was that the external monitor needed more energy than what the HDMI port could supply (we heard lots of beeping connecting and disconnecting). I purchased a simple USB-C to HDMI cable, connected them up and it worked. I connected through the Thunderbolt port...so will need to find a hub solution that works so that I can charge and view at the same time...but at least for now I can see my screen in full 4K. Good luck to everyone else that might get this issue, hope this helps!

 

Thanx, bob.

Cannot connect 4k display to Spectre x360

I have been connecting my HP Spectre x360 to an external Dell 4K monitor for months.  I connect it using a USB-C to HDMI cable.  Today, the monitor says that there's no HDMI signal, but the screen on the laptop is working fine.  The external monitor is working normally; I was able to plug in another laptop using the displayport.  Both of the USB-C ports on the laptop are working normally, so it's not that.  I changed the cable but that didn't work.  I've obviously restarted the laptop and monitor multiple times.  I've run Windows Update.  What could be wrong?

Thanks very much.  I had updated my BIOS and drivers, but hadn't a hard reset.  the drivers were reinstalled and the problem resolved itself.  I think it was a matter of clashing updates, or an update that needed to be patched.
