Its my final approach on this.
I can change the eyepair distance and switch it on and off. It should be a very weak effect by now - need to find a test 3D Television or a 3D Beamer to find good values.
Just wanted to share my current state

Hi,
Were you able to run stereoscopic 3D in unreal engine 4.14.3 ?
Thanks
I am also looking for this solution… looking forward to your reply…thanks
This plugin “iLocalPlayer4UE4” (iLocalPlayer4UE4 in Code Plugins - UE Marketplace) will help you get the correct Side-by-Side Stereo-3D effect.
@shadowcrew We submitted a new Pull-Request into “EpicGames/UnrealEngine:master” to fix the issue(When capturing a movie in the sequencer, Side-by-Side Stereo-3D effect is not correct). The Pull-Request Link: https://github.com/EpicGames/UnrealEngine/pull/4370
