At home I use two monitors, and I have to connect one of them using a USB-C to HDMI adapter (my PC only has 1 HDMI). Previously, this adapter method has worked flawlessly since I got this laptop. But, this morning when I logged in, I had no output to my display that utilizes the adapter. My computer is recognizing the USB-C to HDMI adapter as a 'Billboard Device' instead of the monitor itself.
So far I've tried the following troubleshooting methods:
- Swapped to a new USB-C to HDMI adapter
- Swapped HDMI cable in use
- Restarted/Updated all devices
- Uninstalled/reinstalled NVIDIA Display adapter driver
- Rolled back to a previous NVIDIA Display adapter driver (looks like a new one was installed automatically on 5/2)
- Confirmed my USB-C port supports "Displayport Alt Mode"
Here's the specific devices being used too, in case that helps:
Dell S2721DGF Display <--> High Speed HDMI Cable <--> Anker Powerexpand+ HDMI to USB-C adapter <---> ASUS TUF Gaming A17 Laptop
Do you guys have any ideas? I'm pretty stumped. Have no idea why it seemingly quit working on me overnight.
