Hi all!
So, I've come across a strange issue with my graphics card and/or monitor that is baffling me.
Issue:
When my desktop graphics card is connected to my monitor via HDMI, a "HDMI No Signal" is displayed. There is no video on this monitor at all, not even at bios start. This connection has worked for the past year and suddenly stopped working. The DVI connection between the graphics card and monitor work as expected.
Oddity:
I can connect another device (a laptop) up to the monitor via HDMI and I get video.
I can connect the computer that is experiencing the issue up to a TV via HDMI and I get video.
Therefore, the monitor's HDMI works independently, and the graphics card's HDMI works independently.
Troubleshooting Tried:
Question:
Does anyone know how to fix this issue or have any clue what is going on? The only suspicion I have is that my particular graphics card and particular monitor are having problems with the HDMI handshake all of the sudden.

Troubleshooting Tried:
■ Remove all video drivers and reinstall.
■ Flash Motherboard Bios with latest update.
■ Tried connecting with several different HDMI cables.
■ Connect another device (a laptop) to the Monitor via HDMI. Video is displayed properly.
■ Connect the computer experiencing the issue to another display (a TV) via HDMI. Video is displayed properly.
■ Borrowed a displayport to DVI converter, connected it to the graphics card and to the monitor via DVI. Video is displayed properly.
■ Purchased a displayport to HDMI cable, connected it to the graphics card and to the monitor via HDMI. Video is NOT displayed.
■ This sounds cliché, but I keep a clean PC and don't suspect it is a virus, especially given I don't get any video at bios start.
■ The monitor does not show up in the device manager at all.
