BRAVIA video processing improves low-quality signals
High-definition video sources look stunning on the KDL-40V4100, this logic board offers excellent video processing. Sony's BRAVIA Engine 2™ circuitry cleans up lower-res signals by analyzing and processing each scene to enhance picture contrast, reduce noise, and optimize color.
Another quality that often separates top-notch TVs from no-name models is picture contrast. Sony's Advanced Contrast Enhancer continuously monitors the video signal and adjusts the TV's back-light levels to improve contrast without masking details in darker areas of the picture.
So many viewing options
The KDL-40V4100 has built-in tuners for your local digital and analog over-the-air broadcasts (antenna required). Plus, a "QAM" cable TV tuner lets cable subscribers watch unscrambled channels without a set-top box — including HD channels in many areas.
The generous "jack pack" has multiple inputs for high-resolution sources. For future-readiness, there are four HDMI inputs, so you can add an HD satellite receiver as well as an "up-converting" DVD player or HD video game console
