Sony is stepping squarely into the high-end TV market with the release of their Z Series 4K HDR Ultra HD line. HDR is High Dynamic Range, which means hyper-realistic, deeper blacks and super high contrast—this is achieved with Sony’s Backlight Master Drive Technology, which, Sony says, takes the 4K Ultra HD experience a step further into the future. 65, 75 and 100-inch models will be available.
