At the moment, you can get the early bird discount which gets you the monitor and the lifetime software for 399.
For realtime 3D conversion you need a 3000 series GPU or a certain type of Mac

I had a 3D monitor years ago and the only game that supported it was Lord of the Rings. Glasses or not, I wasn't impressed.
That said, the glasses caused major headaches. It felt like being on the cusp of a seizure.
This one is realtime conversion. Anything can be 3D. Any movie, game, photo, website, etc.
Plus native 3D games, if you use Reshade with the 3D plugin.
Other 3D games are certain PS3 titles on RPCS3, 3DS library via the 3DS emulator, and Dolphin which supports 3D support for games.
For anything else you can use the realtime 3D conversion, which converts everything on the fly to 3D.
I'm not part of the kickstarter, but my youtube page has used this software to convert stuff to 3D. That's why I'm interested in it. Getting the monitor because currently, putting on a VR helmet everytime I want to see something converted to 3D is a hassle.
