The TV is 3D, but the HT system is not a 3D enabled Blu-Ray player. Not all Blu-Ray players are 3D Blu-Ray players.
So like any other non-3D device, it will send a 2D picture, and the television will have to do the 2D-to-3D conversion by doing that processing in the TV.
If you have a 3D Blu-Ray player or HT system, then the television would detect the 3D signal that it would send (as a 3D signal) and then automatically set itself up for 3D viewing.
Hi - I have a 46C8000 connected to an HT-BD8200 via an HDMI 1.4 cable. When I try to play my first 3d Blu-ray disc ("Grand Canyon") the first screen comes up and asks me to select best view '2D, side by side or over and under'. Well it looks like my picture is already a good 3D one and so 2D (ie as is) is the best view - the other two options split the picture into the style specified. With a 2D selection I cannot then go on to select to play as a 3D movie and am told my setup is not 3D capable.
The TV manual appears to say that the set will detect a proper Blu-Ray disc and set itself up for 3D viewing which is what appears to be happening.
How do I get to watch my disc in 3D? TKIA
