Getting no singal on the external monitor(ACER) when it is connected to my HP pavilion laptop

[manuel_michael]

Getting no singal on the external monitor(ACER) when it is connected to my HP pavilion laptop through VGA port. The set up was working properly till this time and suddenly it is not working.

I tried the possibility of connecting the extrenal monitor to another laptop and it is working perfectly fine, so i believe there is no issue with external monitor or its VGA connector.

My laptop configurations:

HP Pavilion dv6-2173cl Entertainment Notebook PC

Windows 7

NVIDIA GeForce G105M

Also i tried to update NVIDIA but when i checked(through device manager / display adapters) it is said that is upto date, not sure what to do now. Any insights on this is highly appreciated. Thanks !!!!

Sometimes electrical components needs to have all power sources removed and reintroduced to work properly.  Try performing a hard reset first, if it doesn't work then we'll move to the next step.

To Perform A Hard Reset

• Shut down the computer by going to the Start menu and selecting shut down. (If you have no display, hold the power button down for  5 seconds); (if the computer doesn't power on, move to the next step)
• Disconnect the AC Adapter from the notebook.
• Remove the battery from the bottom of the notebook.  There will be a switch/button to eject the battery.
• Wait at least 1 minute with all power sources disconnected.
• Re-insert the battery and reconnect the AC Adapter and then attempt to power on the notebook.

No luck.. it is not working. 

Two more points i want to mention: 1. my laptop monitor works perfectly fine and when i connect to external monitor like ACER, i'm getting in the external monitor only 2. i believe my laptop recognizes the external monitor because when i check in some settings with the connection, it says the ACER product as second display, so the problem is no signal coming in my acer monitor

Thanks

Any suggestions to resolve the issue?

As i said, my external monitor is getting recognized - coz i can see that as device under "View devices and printers" in control panel, but in the external monitor - i'm still getting as "No Signal" 😞

Appreciate any thoughts / resolution. 

Thanks,

Hello,

My Laptop's VGA port had issues, so the issue is still there but i stopped using it and using HDMI port for my external monitor connectivty.
