Sony BRAVIA W Series 40 inch KDL-40W4100, 46 inch KDL-46W4100 and 52 inch KDL-52W4100 Full HD 1080p LCD HDTV Review

Sony’s W Series W4100 models (KDL-40W4100, KDL-46W4100 and KDL-52W4100) are third tier members of the 1080p line of LCD flat panel HDTVs introduced at the start of 2008. Full HD, 1080p, resolution provides advantages like being able to sit closer to the screen and avoiding the necessity of downconverting from a full HD video signal source such as a Blu-ray Disc to the native resolution of the display. The avoiding downconverting advantage will gain importance as full HD Blu-ray Discs become more common.

Sony BRAVIA W Series KDL-46W4100

Sony BRAVIA W series shares the same base specification as the V series with the following additions/differences.

Improved contrast ratio of 30,000:1 compared to the 25,000:1 of the S and V series models.

Sony’s Motionflow 120Hz Technology which deals with two problems; LCD blur commonly associated with fast action movies or sports and frame rate conversion judder linked to playback of movies shot at 24 fps. The Motionflow algorithm identifies film content and removes judder resulting in a clearer picture with smoother motion during sweeping pans without a visible jerking or stuttering. Motionflow 120Hz also boosts the frame rate from 60 to 120 unique frames inserting an additional 60 interpolated frames between each of the existing 60 frames minimizing any blur resulting from fast on-screen action.
