Custom VR desktop window

Hi,

Can I configure the desktop window when my VR app is running?? By default the unreal desktop window is vertical with black borders but “The Lab” for example has the correct ratio and the fullscreen option is also available.

Thanks

Anyone? I’m also wondering the same question here. Either’s either a square vertical box or the 2 ugly *** overlapping circles… There has to be a way to render to a regular 16:9 window
