Well it has it for 4:3 sources, but not for HD sources. Here is a quote from a review on the TV.
"There are also four selectable aspect ratios (Sharp calls this "View Mode"). For standard definition resolutions you get Side Bar (unmodified 4:3 on the wide screen with black side bars), Smart Stretch (one of those stretchy modes for filling the 16:9 screen with a 4:3 image), Zoom (for letterbox widescreen sources, incorrectly described in the manual as suitable for anamorphic 2.35 DVDs), and Stretch (for anamorphic sources). With 720p and 1080i sources the set is locked into the Stretch mode."
