Monitor displays "check video cable" when plugging in VGA/HDMI cable

[Sarah_17]

I build a new computer and the fans spin/motherboard lights up when I turn on the computer. However, the monitor doesn't display anything but the message "check video cable". The monitor is the HP 2311x and I plugged in the HDMI/VGA cables separately/together to no avail. I have tried this with both the GPU and motherboard. Windows does not boot and I can't access the BIOS either. The screen also displays "HDMI: not active
DVI: not active
VGA: active" I also cannot access the monitor's settings since the menu doesn't pop up when I press the monitor buttons.

Only attach one active video cable to the monitor.

Try a monitor reset. Unplug the monitor’s power cord and hold down the monitor’s power button for 30-60 seconds. Plug the monitor back in and power it up. Now reset the Source input in the monitor's menu to DVI.

Try the monitor on another PC using DVI.

The monitor reset didn't work. I decided to connect a different monitor (which turned out to be a TV) instead and I connected it using the HDMI cable. On the TV screen it still says "No signal".

are you able to select the source input to HDMI?

On the monitor HDMI is already set as the default yet it says no signal. On the TV screen yes I am able to select HDMI1/HDMI2.
