external monitor shows no signal error

[mssjaney]

When I connected the new Acer external monitor via VGA connector to my HP notebook, I got "No signal" notification on the external monitor.

I have checked it with my other Asus notebook and the monitor works perfectly fine.

Hi,

unfortunatelly none of the stated actions worked for me. i still get the same "No signal" message when i plug in my external monitor.

in step three:

"Uninstall graphic driver already installed in your system from Device Manager"

i clicked on the Device Manager and uninstalled the driver under:

Display adapters > Standard VGA Graphics Adapter

and that didn't help either but instead my whole graphics on the notebook monitor looks very big and weird. i need to fix that too now.

i downloaded the driver you suggested, and installed it, but that didn't help neither.

what else can i try to fix all these problems?

thank you in advance.

Hi,


What is the exact product number of your laptop?

Does your laptop come with integrated Intel graphics or Intel/AMD switchable graphics?

Since there was no Intel or Intel/AMD graphics listed in device manager previously, you obviously need to install graphics driver first.

Please uninstall Intel driver you've just installed now, from device manager and install this:

Intel chipset:
https://support.hp.com/in-en/drivers/selfservice/swdetails/hp-250-g5-notebook-pc/10180321/swItemId/o...

Restart system after installation completes

Then install,
Intel/AMD switchable driver:
https://support.hp.com/in-en/drivers/selfservice/swdetails/hp-250-g5-notebook-pc/10180321/swItemId/o...

Restart system after successful installation.

Then try to connect VGA cable to monitor and check
