I am running Unreal Engine in VR mode on an HTC Vive. The desktop viewport only fills in with a portrait view of the scene (see attached image). Is there a way to have the viewport on the desktop showing the VR experience fill the screen?

Dose anybody know how to fill the viewport？

Thanks!

See this post Problem about monitor resolution display in vive vr mode - XR Development - Unreal Engine Forums, you have to edit SteamVRRender.cpp in the source code
