[SOLVED] How Do Dual Monitors On The RPi4B Function?

Fri Oct 18, 2019 4:49 am

I now have my RPi4B 4GB almost set up the way I want it as my computer system, currently using a single monitor. I am interested in trying out the RPi4B with dual monitors. Before I go the added expense of buying another monitor, I have a question.

With the RPi4B set up using dual monitors, can I have one monitor say playing a video while I simultaneously use the other monitor for word processing?

If you want too, I would rather code.

Most DVI monitors just need a HDMI to DVI adapter and old DVI monitors are free or cheap.
Two 21:9 curved monitors should work too if you have the money :D

The cables need small ends so they can fit.
The Official cables work well and are not very expensive.

Thank you for your reply. I assume that your reply means that I can have a different program running simultaneously on each monitor. That is what I need to be able to do.

What you want to do is irrelevant to the OPs question. So why state it?

The two monitors are combined into a single logical desktop, so you can move application windows between the two.

You can adjust the logical layout of the two screens, "left/right" or "above/below" to match the physical layout.

You can certainly watch videos in a browser window (or in "full screen" **) on one monitor and and have other applications (e.g. email) on the other monitor.

Thank you for the replies. Looks like it will be beneficial to me to have a dual monitor setup. I will order another monitor next week after I return home from HK.
