AFAIK Sony only sells 40 or 46" LCD TVs. Those are the only ones i've ever seen advertised (including websites/stores etc).
From Wikipedia (Full HD):
1080p can be referred to as full HD or full high definition although 1080i is also "Full HD" (1920x1080 pixels). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total.
In addition, "HD-ready" requirement:
Native resolution of the display has to be at least 720 (hence 720p) vertical physical lines and having a 16:9 widescreen aspect ratio.
Also, when speaking of televisions and other monitors intended for consumer entertainment use, WXGA is generally understood to refer to a resolution of 1366×768, with an aspect ratio of 16:9 (ie TVs).
