Genius Hack to Turn 1 Windows Laptop Screen into 1 Screens Using HDMI

If you have a Windows laptop, you may think it only has one screen. But you can use a hack to create a second screen on the laptop screen. Use this second screen for PowerPoint Presenter View and to share your slides in a Zoom or Teams meeting.

Here’s an animated summary of the process.

You connect an HDMI cable to your laptop. This usually involves using an adapter as most laptops today do not have HDMI ports (I have links to the adapters I recommend below). This is a second screen signal that is coming from the laptop. The other end of the HDMI cable gets connected to a Video Capture device (link below) that turns the signal into a camera input. The Video Capture device gets plugged into a USB port on the laptop. Using the Webcam Viewer app (link below) you can see the second screen in a window on your laptop screen. You can use the second screen in PowerPoint Presenter View and even share it in a virtual Teams or Zoom meeting.

Here’s a full video explanation and demonstration.
