'Stereo Display' and 'Split Stereo Display' options missing in 2017.3?

I currently have 2017.1.0f3 and 2017.3.0b6 installed on my system. I was previously using the VR Supported SDK option of "Stereo Display (non head-mounted)" on my 2017.1.0f3 project:




I found a thread that stated that the stereoConvergence property was not working in 2017.1 but Unity had it marked as fixed in version 2017.2. So I tried to port my project to 2017.3.0b6 which I had previously installed, but I could no longer find the setting:



Has "Stereo Display" and "Split Stereo Display" been obsoleted, or is there some other way of enabling this on 2017.2 and above? I have a 3D DLP Projector, and this setting is required to enable 3D for my Unity app.

Any help or guidance would be greatly appreciated!

 

you'll find it again in 2017.3 final/current version (and 'mock hmd vive' is the new name for Split Stereo Display).

 

OK, thanks for the info @Gruguir! I'll download the final version then.
