Win HOW TO - Kodi 2D - 3D - UHD (4k) HDR Guide Internal & External Players
Unfortunately it doesn't help to initialize the stereoscopic mode via the nvidia Control panel and toggle with nvstlink.exe afterwards.

It's not supposed to. The 2 .bat files do and only when the proper rule is called via the playercorefactory.xml. This fix does exactly the opposite and forces windows and NVidia to disable 3D on boot so that when a 2D file is played, it isn't trying to play while everything is in 3D. When a 3D title is played, playercorefactory looks at the rules and hands it off to the 3D.bat. In turn the bat triggers nvstlink to enable during playback and disable when finished. This way you can play a 2D title right after you play a 3D because 3D has been disabled. After a reboot, the nvstlink is not going to function 100%. I know it used to prior to W10 and Nvidia driver upgrades. It simply does not work correctly anymore. You may think it's working, and there are a few indicators that also think it's working, but it isn't.

In my case the stereoscopic mode never works when I toggle it on via nvstlink.exe even though I switched it on before in the nvidia Control panel.
Though, when I use the nvidia Control panel only 3D mode works.

Yep. That's the problem. I ran into the same thing. That's why I diagnosed and provided the fix. Why are you toggling and switching manually for anything? You DO NOT want to enable 3D manually no matter what you are used to, what you have read, what you've been told, or what your common sense says. Let the code do it. I suggest you follow the guide slowly and precisely and 2nd guess nothing. 1 little mistake is all it takes for things to malfunction, otherwise it's working pretty decent here. If you're certain you have done everything correctly, I have no answer for you without more precise details that would help me understand what is malfunctioning for you. Start at the beginning. Reboot. Open Nvidia control panel stereoscopic tab. Is it unchecked? It should be. Play a 3D title and minimize your external player and Kodi. Is stereoscopic checked now? It should be. Etc. Please don't forget to rate the thread. Thanks.
