Zenith Electronics has introduced its "43 Series" PCZTV computer, to-TV color television sets, featuring new advanced scan conversion technology capabilities and added functionality specifically designed for use in the classroom. These 25-, 27-, 32- and 36-inch television monitors incorporate advanced video scan conversion technology, providing higher resolution capability for computer-to-TV imagery and compatibility with most computer systems currently in use.

Based upon sophisticated four-line averaging technology, Zeniths PCZTV approach allows large-screen TVs to display crisp, computer-generated images from any personal computer running a DOS, Windows or Mac application. With high resolution, high quality large screen images, this monitor can put an end to the days of students crowding around a single, small computer screen in order to see what the teacher is showing on the computer. Students can view computer-generated images on a single large-screen PCZTV or multiple units.

A mirroring capability allows users to simultaneously view images on both the computer and the PCZTV. Zoom and Pan capability lets users zoom in on a particular part of the television screen and includes a 2-to-1 zoom feature with horizontal and vertical panning. Automatic Fit-to-Screen technology sizes computer images to fit the TV screen. CamPort front panel audio/video jacks automatically sense a connection and accept input from VCRs, laser disc players and other video equipment.
