Question about the "Triple monitor setup" video.

[Single Core]

Hi there

 

I am talking about this video: https://www.youtube.com/watch?v=8ZQl3HTNXpo

 

In the video Anthony says: "its missing what's behind the bezel, the game itself, i think, isn't even showing that".

But as far as I know you don't lose any data between your bezels, unless you enable some sort of feature which introduces this, which would just be extremely weird in my opinion.

 

Can anyone shed some light as to why he says this?
