Two HMDI Monitors Using Pi 400 [Is it Possible?]

I have installed OSMC 2022.03-1 on my PI 400. I have identical monitors plugged into HDMI 0 and HDMI 1. During the boot sequence, both monitors display the same data. Once OSMC loads KODI, only one display shows anything, the other is blank. If I exit KODI and go to Command Line, both displays are working again.

I have gone into the Systems Settings to look for display configurations, but I am only able to find configurations for the working monitor. I have swapped cables, used either monitor successfully, just not at the same time.

Is there a way to have OSMC/KODI display to both monitors? I am creating custom monitors for the back row of my truck and would like be able to utilize both monitors without having to purchase an HDMI splitter when I have an RPI 400 that already supports Dual Displays.

Any suggestions on how to get both displays working? I thank all of you who have read this post and have considered ways to help me find a solution.

You’ll need a splitter. Kodi doesn’t support dual output.

Thank you for the quick response. I will adjust my approach and get a splitter.
