How to Add an Additional Monitor to Your Computer

Last Updated: June 3, 2021

If you need to be able to do two things at once, then this article is for you. You will need a computer that has a receptacle for a second monitor to be attached, and that the computer (or your software) supports parallel processing of two different programs or two processes of the same/one program, on the two monitors, or you would have the same image on each one.

Steps

1
Plug the 2nd monitor into the wall.
2
Look on the back of the computer and find a VGA spot.

Question

How do I add an external monitor to my laptop? I'm running Windows 10 on an ASUS HDMI.

Community Answer

Just get a monitor or TV and plug it in to your laptop using the HDMI Cable. Then, turn on the monitor and change the channel to the HDMI. Then it should work. If I doesn't, then you have a driver or cable problem.
Question

What if the "Apply" box is not highlighted?

Then it is not available to you - the document must have a secure password on it.
