Im new in UE4 and I’m having problem after i build my project in windows 64 bit. Im previously using 4.15 and upgraded my project to 4.16, then after i build in 4.16 the build starts in stereo mode which when i do the standalone preview everything is normal.
Go to Editor Preferences > Play > Emulate Stereo. Make sure Emulate Stereo is false. Mine was enabled somehow, maybe there’s a hotkey that toggles that I’m not aware of.
