IMAX的3D投影机，详见http://avbuzz.com/bbs/av/av-thread-114519.html红字部份好像说，IMAX也准备用索尼的两台4K投影机，但两台画质不一定比一台画质好。


IMAX Digital

A digital version of IMAX started rolling out in 2008. The new system is a projection standard only; there are no digital IMAX cameras.[citation needed]

Digital IMAX systems can show either normal or 3D content in DCI or IMAX digital format (which in itself is a superset of DCI). The digital system alleviates the need for the use of bulky film reels and facilitate inexpensive distribution of IMAX features, the more compact nature of digital equipment means the system can fit inside a normal multiplex cinema complex rather than the specialised buildings IMAX normally requires.[citation needed]

Despite those advantages, one big disadvantage is the resolution of the picture is much lower than normal IMAX. The screens used by digital IMAX installations are also much smaller (28x58 feet) than those found in traditional IMAX cinemas. The digital installations have drawn some confusion based on poor consumer differentiation to the traditional 15/70 IMAX.[6]

Deals have already been signed with Hollywood studios for IMAX 3D features, such as "Shrek Forever After 3D".[7]

IMAX digital currently uses two 2K-resolution Christie projectors with Texas Instruments Digital Light Processing technology alongside parts of IMAX's proprietary system. The two 2K images are projected over each other, producing an image that is potentially of a slightly higher resolution than common 2K digital cinema. Originally, IMAX had been considering using two Sony 4K projectors.[8] Some reviewers note that this approach may not produce image quality higher than using one 4K projector, which are available for some non-IMAX theaters,[6] including AMC's own. [9]

IMAX recently signed a deal with AMC to start utilizing IMAX digital beginning July 2008 in the US. In December 2008 two digital screens were opened inside Odeon Cinemas in the UK[10] and three inside Hoyts Cinemas in Australia with a fourth to follow later in 2009[11].

这次数码版IMAX的AVATOR在美国那边放的时候出了问题，能看胶片版的还是去看胶片版吧，不过国内上胶片版的好像只有东莞和北京。

请教一下美国那边出了什么问题呢？
