VR Oculus Dividing the image on the monitor

How to disable the division of the image on a computer monitor? The example in the image below. On the left image on the monitor. Right on the Oculus Rift image

P.S. Unity 5

do you mean you’re using unity 5 or what?

no. In Unity5 it works as it should. The screen on the monitor is not bisected. When do the same in UE4?

Ah! I get you now, cheers

You could try to use console command ‘hmd mirror mode 2’ for that (but that’s currently buggy, at least in 4.8)

it is necessary that it is realized qualitatively in Unity5
