Split One Monitor Into Two Virtual

less than 1 minute read


I had an issue where my Dell U3419W monitor would show windows side by side easily, but it was a huge pain to share my screen during collaboration sessions which I needed to do often. What I needed was software to split my screen into two monitors

To Resolve:

  1. So I originally had just a single USB-C connecting to my laptop, the fix was to add a HDMI from the screen to my laptop and:
    • Download/Run Dell Display Manager
      • Go to input - Main Window #1 = USB-C / Sub Window #2 = HDMI#1
    • In addition, use Intel HD Graphics Control panel to set each window to 1720*1440 and Scale Full Screen (under Display)
