Is the format frame-packed MPEG4-MVC? Is it a direct, uncompressed rip? 3D MVC is the only 3D format supported by madVR.

 Here is the info of the file that I'm testing. It's not a direct/uncompressed rip.

Here is the info from Kodi 3D Sample

The only difference I see is that the Kodi sample has Format profile of Stereo [email protected] / [email protected] while my file has [email protected]

Hi Warner.  That's a good thought.  To satisfy the OP that madVR is not responsible, we can simply eliminate it.  In MPC, change the preferred renderer from madVR to Default.  madVR will be out of the equation.  Your SBS.mkv should open in twin screens very briefly, your display should flash black as it goes into SBS or TAB, and a moment later it should display 3D with the two images overlapped.

Tried that, all I see is two pictures side by side. Switching 3D modes on my Pj does not do anything either. On the flip side, I play the same file in Kodi, it shows the option to play as Stereoscopic 3D and then I simply change my Pj 3D mode to Side-by-Side and it works. Also, if I play a 3D Blu-ray via Xbone X, it works as expected. 

The only work around that I can think of is to keep the resolution as 4k/60 but add 1080p/24 in madVR so that it can switch to that resolution with 3D is played and not upscale it?
