Hi Sivaram,

Thank you for writing to Microsoft Community Forums.

1. Since when are you facing this issue?
   

This issue might be happening because of the faulty drivers. That’s the reason you are getting intermittent connection on external monitor.

However, you may try the below suggested steps.

Step 1: Try connecting on a different monitor and check if the issue still persists.

Step 2: Try using a different VGA cable to connect with external monitor and check the status of the issue.

Step 3: Update display driver adapters

You may refer the article
Update drivers in Windows 10 and check the status of the issue.

Step 4: Check for an updated Video driver on the

Acer drivers and Manuals page.

I can not format laptop HP Pavilion 15t-eg0000 from external bootable

I have some issue on the windows of my new laptop. I downloaded WIN 10 iso file from Microsoft website then attached to the external USB via RUFUS app. The USB is bootable and recognized by the laptop but the local drive is not showing on the list of the drive. Is this a new security step on the BIOS? Please help me to sort out this issue.
