DESC: FST Pure CRT features a flat-glass viewing surface, which lets you see more picture from a greater range of angles, with less light reflection compared to a traditional radius CRT. ColorStream Component Video Inputs allow the base broadcast signals to be displayed individually without being processed, which results in better picture quality and stunning color reproduction. Stable Sound allows you to maintain a consistent sound volume when the program changes to different material, such as a commercial. 3-Line Digital Comb Filter separates the overlapping Y (brightness) and C (color) broadcast signals, which prevents color smudging and vibrating edges, and ensures sharp detail.
