Mirror displaying handphone screen on monitor and vice versa with WiFi connection using LetsView

If you are using an iPhone or Android phone, and you want to duplicate and show your handphone's screen on your computer monitor, laptop screen, or even smart TV screen, together with audio forwarding, you can easily do that with a free software called LetsView.

The beauty of LetsView is that it can also do the other way round, to duplicate your computer screen onto your handphone. This is pretty useful to make use of your handphone or tablet as a presentation control device, which you can control your computer screen (which can be in turn projected out to a large projector screen) by touching your handphone screen. You can perform drawing and highlighting with LetsView too.

LetsView can also perform computer to computer screen mirroring.

All you need is:

  • Download and install LetsView, free of charge, in both the screen mirroring source and destination devices. Supported systems including Windows, Android, Mac OS, iOS, and TV.
  • Connect both the devices into the same local network. The network connection can be using WiFi or LAN cable. It can work across VPN tunnel too.
  • Run LetsView in both devices.

Running LetsView app in smartphone is pretty straightforward. When the app is able to detect another device in the same local network running LetsView, you will eventually step into the following screen.

Phone Screen Mirroring means to cast your phone screen, together with phone audio, to a computer screen.

Computer Screen Mirroring means to cast your computer screen to the phone.

The screenshot below is captured from my computer monitor, showing the LetsView software displaying my phone screen on it.

When your phone screen is placed in landscape mode, the mirrored one on computer screen will also be displayed in landscape mode.

In your LetsView computer software, you also have the option for Phone Screen Mirroring and Computer Screen Mirroring. If you choose Computer Screen Mirroring, your computer screen, as well as your computer audio, will be mirrored to another computer running LetsView. The receiver will need to key in the PIN code as shown in LetsView of the source computer, for security purpose.

Before the computer screen starts to mirror to the receiver, a confirmation dialog will popup on the screen of the source computer, and you'll need to Allow it to complete the process.

The source computer can choose to either mirror the entire screen to the receiver, or just to mirror the screen of an application currently running on it.

Here is how the screen of the source computer will be shown in LetsView of the receiver computer.

LetsView is pretty useful when you want to work with your computer, while at the same time need to have a glance to your phone's screen from time to time. By showing the phone's screen on your monitor, it is very convenient to see what is on your phone's screen even without touching your phone.

This is also useful if you want to show both your computer screen and your phone screen to your audience in a presentation or live streaming session.

On the other hand, by mirroring your computer screen to your phone or tablet, you can transform your phone/tablet into a pretty powerful presenter device to remote control your computer screen. You can even write or draw on your phone's screen, and make it appears on the larger screen, by using LetsView whiteboard and drawing utility function.
