The colors produced by the 5 segment color wheel of the set are rich and vivid and give the viewer an ultimate viewing experience. A three line digital comb filter is used to eliminate any visual interference.
Two built in speaker are attached to the cabinet and produce a total output of 20 watts (10 X 2) to give excellent sound quality. The speakers also have surround sound qualities which further enhances the sound quality.
