We first saw the retail edition of Toshiba’s 3840×2160 resolution autostereoscopic (no glasses) 3DTV when it was announced in Europe at IFA last month, and now it has debuted in Japan during CEATEC. This time the company revealed a few more details, revealing that in lenticular 3D mode it’s limited to an effective resolution of 1280×720, and showed off the face tracking that automatically optimizes the experience for up to nine simultaneous viewers depending on where they’re sitting. Also mentioned were an optional THD-MBA1 input adapter due in 2012 and that 4K-res streaming IPTV is currently being tested. The Regza 55X3 will be priced comparably to its $10K~ Euro-spec counterpart when it arrives in December, but there’s still no word on when it will ship in the US. Check out a few pictures of the presentation in the gallery below.
