It sound so like it should be so simple....

Looking for a 4K 3D TV and the market seems to consist of only LG and Sony's top of the line markets.
Can someone explain why it is not possible for a blu-ray player to decode the info from the disc, create the final image, and pass it along to the TV unchanged.

Thanks.

If you want to buy one new you shouldn't wait long. LG's 2016 models are the last to feature 3D same with Sony.

Your second question, more info might be needed what you're asking. In fact I believe that is what they do, it's up to your display if it can accept the 3D signal.

This line intentionally left blank.

Modern digital 2D TVs cannot display stereoscopic 3D content.
You need something extra to do it, and is no universal way to do it.

This extra thing costs money to implement in the TVs, and manufacturers want to keep that money for themselves, so you get no free feature unless the manufacturers feel they'll loose sales from missing the feature.
After a few years of pushing 3D everywhere, they noticed that only a small percentage of buyers among the high-end actually used the 3D feature, so they no longer implemented it in their low-end products.

And about the specific question about BluRay3D format : there are many different ways to display stereoscopic 3D on a 3DTV depending on the technology used (passive glasses, active glasses or multiple glasses-free systems).
Therefore, in order to make one disc compatible with all systems the disc contains the stereoscopic image in a format that is 3D technology neutral.
When the TV receives the picture from the BluRay 3D player, it transforms this neutral universal picture into whatever format it needs to create the 3D effect.

Passive 3D, forever !
My Full-HD dual-projector passive polarised 3D setup. (really out of date ! I need to update it some day...)
