UE3 - UDK Cannot enable secondary display

  • Two Factor Authentication is now available on BeyondUnreal Forums. To configure it, visit your Profile and look for the "Two Step Verification" option on the left side. We can send codes via email (may be slower) or you can set up any TOTP Authenticator app on your phone (Authy, Google Authenticator, etc) to deliver codes. It is highly recommended that you configure this to keep your account safe.

Does anyone know how to enable the secondary display in UDK? I have changed BaseEngine.ini and BaseSystemSettings.ini to include the following:

BaseEngine.ini
Code:
; Whether secondary displays are allowed
AllowSecondaryDisplays=True
;
; The maximum allowed width and height of secondary displays
SecondaryDisplayMaximumWidth=1280.0
SecondaryDisplayMaximumHeight=720.0

BaseSystemSettings.ini
Code:
GameViewportClientClassName=Engine.GameViewportClient
SecondaryViewportClientClassName=Engine.GameViewportClient

If I understand correctly, this should create a seconary output the same as the primary one. But all I get is a very small secondary screen that consists only of the title bar (red arrow):

I have found that documentation on this issue is a little hard to come by. What am I doing wrong?
