USB C to HDMI not working


Got a Yoga 920 earlier this week. Plugged my USB C to HDMI adapter in and it worked for a few minutes and than stopped working.

It is now identifying as a USB 2.0 Billboard Device which I belive means it isn’t configuring Displayport Alternative Mode properly.

Here’s what I’ve tried:

Hitting Windows – P to change project mode.

Going into display settings and detect display.

Checking for Updating graphics driver, USB drivers, check for updates.

Using a different USB C to HDMI adapter, a different TV, and a different cable.

Booting to safe mode with no services running.

Any thoughts for reconfiguring the driver?
