Hello all, i hope this finds you well. I am using Acer Travelmate P449-G3-M, which has a VGA and an HDMI port, i connected my another monitor through the ports but its not working and monitor shows no input from vga/hdmi ports. Is there any solution to this? *both ports are working fine with projectors and other system.

Hi @Anjumsazid07

Please find the below is the weblink that describes how to Setup Dual Monitors to your laptop:

How to set up two monitors

To start your dual monitor setup, you will need to ensure that your second monitor is plugged into a power source and connected to your computer via an HDMI, DisplayPort, or USB-C cable. The Windows software will automatically detect the monitor when you connect your second display to your computer or laptop. Press Window + P to access the display option; you will be presented with four options: PC Screen only, Duplicate, Extend, and Second screen only. To get a two-monitor setup, select Duplicate or Extend.  

If the second monitor does not automatically connect, follow the steps below to learn how to set up a second monitor manually: 

1. Press Windows + I to access your Settings. 
2. In your Settings, go to Systems > Display. If you do not see the monitors, select Detect. 
3. In the Multiple displays section, select an option from the dropdown list to determine how your desktop will display across your screens. The options are the same as the one mentioned in the paragraph above. 
4. Once you have selected what you see on your displays, select Keep changes. 

Now that you know how to set up a second monitor, you can experiment with different monitor placements to find the perfect dual-screen setup for you.
