RealD also provides its RealD Format, active and passive eyewear, and display and gaming technologies to consumer electronics manufacturers and content producers and distributors to enable the delivery and viewing of 3D content on high definition televisions, laptops and other displays.
And passive 3D TVs can only display 3D content at half-resolution: 540 lines, rather than 1080, but the smoother 3D is more noticeable than the lower resolution.
