Sit back, relax, and enjoy the show. Designed for your true viewing pleasure, this 19" diagonal HDTV combines a brilliant widescreen LCD display with 1366x768 HD resolution for a picture that's as lifelike, vibrant, realistic, and clear as the world outside. If you want to personalize the picture, sound, or ambilight settings, a settings assistant wizard guides you through the process step by step. If you want to skip right to the big game or your favorite shows or movies, however, the HDTV has a Digital Crystal Clear Engine that digitally adjusts and optimizes picture quality to optimal contrast, color, and sharpness levels. In other words, you get the perfect picture. From Philips. With a TV that has a built-in high-definition tuner, HDTV may be received from broadcasting companies that transmit high-definition signals, or may require a subscription to a digital cable or satellite service to receive HDTV programming, where available.
