Cannot connect to external monitor

[dbro4231]

I have been having this problem for a long time, and am really at a loss at this point. 

Whenever I connect my laptop to my monitor via a usb-c hdmi adaptor, the connection is recognised with my laptop flickering before returning to normal.

Going to the display settings, I see that the monitor is connected but "display 2 is not active".

I assume this is likely a problem with the driver installed on my laptop but I have had no luck. 

So far I have tried the following: 

- Update drivers

- Use old drivers

- Update bios 

- Updated thunderbolt 3 drivers

- Changes HDMI-adaptors and HDMI cables 

- Complete factory reset

- Changes framerate settings

- Projection settings

- Powering down my monitor 

- HP Support assistant

- Updating to Windows 11 

But nothing works and can show an image on my monitor. 

Any help would be greatly appreciated.

P.S the monitor and adaptors works on other computers.

The same thing happened on my laptop. When I try connecting the laptop to an external display, it shows that is it connected but the second monitor does not display the output. I felt the problem was with my HDMI port, but before that conclusion, I installed Windows 7, 8, and 11 and the problem persisted. I assumed then that it might be a driver issue so I updated, but still, it did not work. So I decided now to just manage just my laptop screen till I can get a better laptop.

However, for you, try to download and install the  Nvidia driver v442.92

This might likely fix the challenge you are facing.

Unfortunately my laptop has an Intel based GPU so an NVIDIA driver wont help. 

Any other suggestions.

Have you tried updating the BIOS? That might help out.

Yeah i've done that. No good 😞

I think the fault is coming from the HDMI slot on your PC, since the HDMI cable worked on other systems.

This is definitely possible. 

I've heard the USB-C ports are known for breaking down and not having a stable connection. 

Im going to try soon to use a USB-A to HDMI adapter and see if that works. If it doesn't, I'm out of luck.
