External display Not detected

Dear experts,
My external monitor connected to cpu through display to hdmi cable is not detected. Please help me to find the reason.
Here are some required files:

Did you connect it to the mainboard output or the nvidia graphics card?

NVIDIA graphics card

Then I suspect there’s an issue with the DisplayPort/HDMI adapter cable, the driver reports all connectors except for the HDMI port as “disconnected”.
