LED HDTV offers full HD 1080p crystal-clear detail and LED backlighting as the foundation for a great picture. Powerful yet thin LEDs deliver a brighter picture than conventional LCD backlighting along with outstanding contrast, rich colors and enhanced dark-scene detail. Everything moves naturally with Motionflow XR 120 technology that delivers clear, realistic sports and movie action. Using a Mobile High-definition Link cable, you can connect your smartphone to the TV to literally "mirror" what's seen on the smartphone screen. Video, photos and apps are re-sized and scaled to fit the larger 40" (diagonal) TV screen. You can also connect a digital camera, USB thumb drive or cloud photo services with the USB input. Versatile HD connections include three HD inputs with two HDMI inputs for sources like your HD cable box, home theater system, Blu-ray Disc player or PS3 system, and one HD component input.
