Have just bought a second hand Oculus CV1 bundle which I viewed working without any issues, I have tried to set up at home and glasses are now only lit up on one side but that is showing stripey lines ?? I plugged them on another computer and all seemed to work fine so does anyone know why this is doing that please ?? I have previously used another CV1 set and never had an issue so cant understand what has changed in the meantime ? Can anyone help please ??
