Fortnite won't go into true full screen, just borderless window saying its in fullscreen

Exactly as the title, I don't know why it's being like this, I could access my other monitor easily which is convenient but I don't feel like I'm getting my full on experience with my 140hz monitor, it doesn't feel smooth most of the time when I play and when I play on CS:GO, it always feels miles smoother than it, even Battlefeild 1 or R6.

Have you tried ALT+ENTER ?

Yeah, it doesn't do anything, just switches back to window and back to "fullscreen".

What cable are you running from your 970 to your Monitor ?

Can you also confirm that other games do act normally and go to fullscreen and it is just Fortnite causing the problem ?

A dvi cable, and how do you think I can prove it?

Do other games work fine ?

Yeah, I'll try unreal tournament to see if that works (another game on the same engine and launcher), but all other games would go into true Fullscreen when I tried, I don't know if it's because of Unreal Engine but...


Ok, so I tried it, and it didn't work or fail the way I expected it, it still didn't feel at all smooth, but whenever I would alt-tab it woul minimize like a true Fullscreen, but whenever I just moved m y cursor to my other screen it wouldn't do anything, I could click, type, everything...
