I’m laughing at this because I didn’t expect anyone to respond but TJPC to respond. My sarcastic response is because he has taken a dump in every thread he can find to bemoan the lack of 3D support. Sorry for your confusion Edwin. To recap: Every Blu-ray player including ps3,PS4 and ps5 will support 3D Blu-ray playback. It’s required by the Blu-ray standard. No, 3D 4K is not a thing. Maybe it will be in the future. There is no guarantee that any device will support it. If you have a Blu-ray deck that will not play a 3D disk, upgrade your firmware. If that does not fix it you have a defective disk or player or user.
