I have an unique use case that I need advice about. It is a Pi4 that's used as an advertising player.
The pi4 is connected to 7" touchscreen via DSI port. The two micro-HDMI ports are connected to external monitors with resolution of 1920x1080 each.
I want to be able to display ads on the two external monitors. Ads would span across both monitors with a resolution of 3840x1080. The 7" touchscreen would have an interface to manage the ads.
Is there a video player that can span across two monitors with resolution of 3840x1080?
I have not been able to find a good discussion/solution around this use case. Thanks for your advice.
