21st Century Television – What To Look For
When they first appeared, large-screen LCD TVs did not have the same breadth of plasma televisions on contrast ratio and response time. Manufacturing developments have conquered the majority of these hurdles and, though plasmas still have a market edge amongst 50”+ screen size, 42 inch LCD TVs and smaller now tally the majority of plasmas on visual excellence.
LCD technology
Each and every pixel on an LCD television screen has a blue, green and red pixel cell, that radiate upon receipt of an electrical charge. Varying the charge alters each pixel’s colour strength; varying strengths among the cells in each pixel alter the color.
Connection Types
High Definition Multimedia Interface (HDMI): This is the standard cabling for most Blu-ray players, video game consoles and home theater systems; it carries both audio and digital video in a single cable.
Component Cable: This analogue video cable is commonly used by DVD players, video game consoles and home theatres and uses 3 separate connectors.
Coaxial: This analog cabling has been used for many years and may connect your satellite or cable set top box to your LCD television.
Optical: This audio cabling is used in higher quality sterio sound systems for its clarity and bandwidth, using light to transmit data.
