How to configure 4 monitors with Xorg and span chrome in kiosk mode to all monitors?

un xcellent

I have 4 monitors, two on top and two on the bottom. They are all the same type of monitor. I would like to open chrome in kiosk mode to span in full screen in all 4 monitors. Or run a video that will be seen in all four monitors in full screen (not a duplicate in each monitor). With the below configuration, I either get a duplicate of the window in all four monitors or the window is on the top left monitor.

Here's my xorg.conf

Section "Monitor"
        Identifier   "DisplayPort-0"
        Option       "Position" "0 0"
EndSection

Section "Monitor"
        Identifier   "DisplayPort-1"
        Option       "RightOf" "DisplayPort-0"
EndSection

Section "Monitor"
        Identifier   "DisplayPort-2"
        Option       "Below" "DisplayPort-0"
EndSection

Section "Monitor"
        Identifier   "DisplayPort-3"
        Option       "Below" "DisplayPort-1"
EndSection

EndSection

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
