People keep asking me, now that HD is here, what comes next? Higher definition HD! Sharp was showing a prototype of a 64" LCD flat panel with 4K resolution, which equates to around 4000 pixels across and 2000 vertical. That adds up to nearly nine million pixels!

While this was a technology showcase with no pending product release planned, don't think that 4K is science fiction. SMPTE has been pushing for digital cinema to move to 4K for some time, and Sony is already pushing SXRD-based digital cinema projectors at that resolution.
