Having more than one monitor is useful for any power user (porn on one, games on another). So it’s possible to use an android device as a secondary monitor, but I recommend actually buying one if you want an easy setup. With that said, if you have a spare Android device laying around, you can use it as another monitor in your setup. To do this, we are going to use Windows and “trick” it into thinking that you have another monitor connected and then use TeamViewer to access the “fake” monitor. This trick will only work with computers and laptops that have an extra VGA port. DVI and HDMI will not work with this. Here’s how to use Android as Second Monitor:
What you will need:
- Windows Computer with VGA Port
- VGA Cable
Step 1: Creating your fake monitor
Go into control panel and display settings. Select the button that is labeled detect. Another monitor will appear neext to your main one. Go to the dropdown menu and select the option connect to VGA anyway. Then select the link that reads project to a second screen. When the Window’s charm menu appears, select the option that says extends.
Step 2: TeamViewer
Download and Install TeamViewer. Then go into Extras and Advanced Options and select the button to install the monitor driver.
Like I mentioned, using Android as second monitor is really cool but not a practical solution. There is some latency lag due to your network and switching between monitors can be a pain. However, it’s still worth a try and provides a nice free solution over the paid apps.
