I have the native 3d youtube app from the Viera connect menu and also an HTPC hooked up via HDMI.
I play the 3D Youtube stuff with all sorts of settings but nothing ever works. I switch the TV to 2d->3d mode and it still doesnt work. Stuff is displayed like it should be in 3d but it looks the same with the glasses on or off, just a garbled sort of mess.
Is there something special I am supposed to do in order to try out some 3d content on the tv? Do I want interleaved? side by side:? over under?
I put the desktop to both 1080p and 720p. I used an ATI based PC and then hooked up an Nvida powered PC.
With the Nvidia I was able to run the stereostropic 3d settings and run the test fine and see stuff in 3D. With youtube I tried all the settings and nothing would come in clear. I also pushed the 2d->3d button on the Panasonic and that didnt do anything either.
I donloaded SBS movie trailers and tried to play them with a Stereostropic player and I could find no setting that would make it work with the 3D glasses.
Does this set have some kind of special 3d that doesnt work with everything else out there?
I didn't have a problem playing 3D Youtube clips on either the built-in Youtube App or on Youtube on an attached PC playing full-screen. Just play a "Side By Side" (SBS) 3D video, and then tell the TV to go to 3D mode. Occasionally, I had to go into that "Sub 3D Menu" you indicated and tell it specifically that it was a Side By Side 3D video, but after that it looked/worked fine.
