Windows 10: One of my monitors does not work with the exact same cable and port that does work for my...

My Asus has stopped working for some reason, it does still turn on but all of the sudden it does not work anymore. When I plug in the cable of my main monitor, which works, into the second monitor the monitor does not go on anymore. Is my second monitor broken?

HDMI Port Stopped Working

I generally use a second monitor via an HDMI cable while working. However, it stopped working today.

I checked these:

• Windows cannot detect a second monitor when HDMI cable is connected to the second monitor.
• HDMI cable which I use works if another device is connected to the second monitor.
• My computer detects my HDMI-to-VGA converter through HDMI port.

My computer runs Windows 10 Home with latest updates installed.

I suspect this is due to a driver error. How can I fix this problem?

 

My connection to the monitor is not working. I have new cables and a new monitor. I have switched cables in the ports and it is the port that doesn't seem to connect.

Windows 11 does not work with Monitor in Display Port, but HDMI ¿?

Thanks, but I've already followed that (obvious) steps...

It's curious:

- If I start the computer with 1 monitor using Hdmi cable, it works (shown windows 11 fine)

- If I start the computer with 2 monitors (1 using hdmi cable, 1 using display port cable), it works (shown windows 11 fine in dual screen)

- If I start the computer with 1 monitor using Display Port cable, it works until windows 11 loads... shown Bios/Post boot... but then black screen not showing windows 11. It's a Microsoft Windows matter. I do press Shift + Start + Ctrl + B (to reset 'graphics') the monitor does a 'flick' but continue without showing windows 11.
