Full screen mode in browser across several monitors

[Janah]

I am trying to get youtube videos to play in fullscreen on 2 monitors at a time with chrome , each time i hit fullscreen it just goes on fullscreen on one monitor, can a browser window run in full screen mode across multiple monitors?

i have a program called DesktopFusion, but i cant seem to find any option for this issue there , is it possible to do this with fusion?

i found a website that does what im talking about , but is there any other ways to do this ? chrome extensions , programs , youtube settings , monitor settings , nvidia settings etc ?

site that does it for u  : www.stretch.site/

I just use the F11 key to stretch by bringing the browser full screen. Each browser should support the F11 key. F11 toggles it on and off.

My cat pointed this out to me one day when walking by.
