Had an LG that even came with those light passive polarizers tech Dual Play glasses that were never used.

Ultimately that novelty came probably too early to mature to acceptable results on 1080p sources and edge-lit LED 1080p panels of that era, if it was ever meant to be.

Might be wortwhile to reintroduce them on 4k with sunlight challenging mini-LEDs as a differentiator vs less brighter OLEDs for more than acceptable results at 3840x1080 and consoles being able to push out that kind of resolution.

Currently console support for splitscreen multiplayer seems to be a dying art over the last decade. But you could still multiplex 2 sources into the same screen though.

Then again there is no replacement for Kinect-like tech either either in current consumer market offerings, I would still take that over most VR experiences in terms of setup/social friction and local/couch coop.
