1440p is a non-standard resolution which is double the vertical resolution of 720p.
In Fall 2006, Chi Mei Optoelectronics (CMO) announced a 47" 1440p LCD panel to be released in Q2 2007[1]; the panel will finally debut at FPD International 2008 in a form on autostereoscopic 3D display. [2]
1440p video is very rare. To promote NVIDIA's Extreme Definition, some trailers have been produced for various games and the movie The Chronicles of Narnia: The Lion, the Witch and the Wardrobe.
Support
1440p video mastered from 4:3 ratio content could be displayed with 1920×1440 or higher resolution such as QXGA or 2304×1440 with scaling, windowboxing, or pillarboxing. Widescreen 16:9 1440p requires 2560×1440 resolution, possible with WQXGA, 2560×1920, or higher resolution with letterboxing, scaling, or windowboxing. Apple's 27" iMac[3] has a resolution of 2560×1440, thereby allowing 1440p widescreen. The HDMI 1.3 specification supports WQXGA, and hence widescreen 1440p.
