These days, the big buzzword in LCD TVs is “120Hz.” What does this mean? In the U.S., video frames are displayed on a TV screen at a rate of 30 or 60 per second. (“Per second” is technically called “hertz,” which is abbreviated “Hz.”) Because fast-moving objects often appear blurred on LCD TVs, manufacturers are now starting to double the rate at which frames are displayed to combat this so-called “motion blur.” The effect of 120Hz operation is often subtle at best, but the JVC LT-47X898 does it right, reducing motion blur to reveal a sharp, clear picture.
|Excellent; items on Morty’s cluttered workbench well defined.||Skin tones somewhat orangish, greens limey.||Letterbox bars unobtrusive.||Not great, detail lost in night scene; entire picture looked too contrasty.||No noise, super-smooth motion.|
|Carved walls and pillars of stone temple very clear, cityscape as Leeloo jumps very sharp.||Blue earth from space almost fluorescent; skin tones better than in Click, but still a bit orangish.||Black of space fairly deep, letterbox bars unobtrusive.||Not great; lots of detail lost in darkened battleship.||No noise, super-smooth motion.|
|Very good; shingles on house clear and crisp.||Green trees and yellow walls exaggerated, skin tones a bit pinkish and pasty.||No opportunity to test.||No opportunity to test.||No problems noted.|

|Surprisingly good for standard- def, especially in closeups; long shots softer.||Skin tones a bit pasty and pink.||Windowbox bars unobtrusive.||Large solid dark areas in night scenes and dark interiors.||Lots of shimmering in pan across pin lights in trees at night, also in lights of Las Vegas; could be in signal.|
On test discs, the JVC LT-47X898’s 120Hz operation reduced motion blur better than any other such LCD TV I’ve seen to date, though the effect was less dramatic on real-world content. Blacks were quite deep, due in part to the fact that the set dynamically changes the black level depending on the overall brightness of the image. The LT-47X898 provides several parameters that control this function, but it is never completely disabled, even when all those parameters are turned off. The color accuracy and shadow detail were of most concern to me, leaving much to be desired. Once JVC addresses those concerns, it will have a real winner on its hands.
