R56W36 is a 56" 16: 9 HDTV Monitor Rear Projection Television. HD Grade Optics improves brightness and focus, and reduces overall cabinet depth. HD Focus is an automatic system that eliminates the need to manually adjust the picture. Simply select HD focus from the onscreen set-up menu, and 16 sensors automatically adjust the picture from center to edge in ten seconds. Most HDTVs use upconversion of analog signals (line-doubling) to simulate an HD picture, which introduces artifacts that appear as pixilated scenes due to digital conversion. Using advanced digital display, these picture artifacts are nearly eliminated. 0.52mm dot pitch improves picture detail. Most movies are shot on film, and film operates at a frame rate of 24fps (frames per second), compared to video which operates at 30fps, 3: 2 pulldown properly detects and syncs film to video for smooth theater like pictures at home. Improved CRTs maximize brightness and picture detail. Specifically developed for digital program content.
