#RaspberryPi – MultiMonitor support in #RaspberryPi4 rocks!

Buy Me A Coffee

Hi !

Another post in my path to use a Raspberry Pi 4 as a fully development device. And today, no code at all, just a showcase of the amazing new hardware: 2 video output. So let’s start with a working mode:

In the previous image, in Screen 1 I’m using an instance of Visual Studio Code to do some Machine Learning with Python, and in Screen 2, I’m also browsing the history of one repo (I broke something …. as usual!).

In Screen 1, I also have Htop running, and it shows that I’m only using +780MBs of ram, that’s mean I still got 3GBs to use!

As a Windows user, I really appreciate that we had an visual interface to configure screen settings.

Raspberry Start > Preferences > Screen Configuration

The [Screen Layout Editor] allows us to configure the following settings for HDMI 1 and HDMI 2 screens:

  • Resolution
  • Frequency
  • Orientation

As you can see in the following image, I got connected a HD monitor in HDMI 1 so my maximum available resolution is 1920×1080.

I haven’t connected a 4K monitor to the device, but I’ll get there 😀

Finally, you can also manage some additional screen configuration from the [Desktop Preferences] settings. I this section you can configure individual wall papers, icons to be displayed and more.

And this is also the section where you can DUPLICATE THE MONITORS ! [Show identical desktop on second monitor].

And, of course, I my demo device is ready for Caribbean Developer Conference 2019!

Happy Coding!
