Can't set proper fullscreen?

After looking online I found out how to change resolutions and supposedly set fullscreen, however when I set fullscreen to 0 it still have the UE4 borders around it, or is that just because I’m running an editor window?

Try using

Execute console command
FULLSCREEN

Not sure what version of the engine WarLord is running, but I’m experiencing a similar issue running 4.7.6 where neither FULLSCREEN nor r.FullScreenMode 0 or 1 do anything.

I have 4.7.6 and FULLSCREEN command set no border windowed mode
