Trying to set up dual monitors on your computer? It’s very easy! Follow the step-by-step instruction below, and you’ll be able to use the
Step 1: Prepare the setup
Before you start to connect your second display to your computer, you should make sure that you have all the cables needed. In addition to power cables, they should include any video cables like VGA, DVI, HDMI or DisplayPort cable (and an audio cable if necessary).
Step 2: Set up your monitors
If everything is ready, plug the cables into their corresponding ports. (Note that if you are using a dedicated graphics card, you should plug the video cable connector to the port as the image below shows)
When you properly connect your monitor, power up your computer. Your computer will automatically detect the second monitor and display your desktop on it. (But what if I can’t?)
Now, you can switch display modes to change how Windows display content on your monitors. To access to display modes, press Win + P. A sidebar would appear on the left.
The differences between these four options are below:
- PC screen only — Only using the first monitor.
- Duplicate — Displaying the same content on both monitors.
- Extend — Using both monitors to display an extended desktop.
- Second screen only — Only using the second monitor.
Step 3: Configure your monitors on your computer
Basically, the steps above can have your dual monitors setup in Windows 10 done. But if you want to customize the way of displaying, right click on the desktop and select Display settings. A window will pop up.
You can click and drag the numbered boxes to rearrange the display. The Identify button can show the number of the monitor.
You can change the size of items and display resolution and orientation.
The display modes mentioned above can also be changed here in Multiple displays.
*Sometimes a second monitor cannot be correctly detected by your computer. This can be caused by improper connection or defective monitor or cables. Ensure all the cables are correctly connected, and do some tests with an alternative monitor and another cable.
