4K Ultra HD Android Smart TV 100Hz Refresh Rate Freesat HD and Freeview HD Dolby Atmos Sony Bravia KD75XH9005BU 75" Full Array LED 4K HDR Android TV The Sony KD75XH9005BU offers a combination of up-to-date features in picture quality, innovative speakers, and smart functionality in a 75" screen size. The Full Array LED system used in the design of this TV is designed to produce versatile picture improvements across anything you watch. The lighting that makes up the image is arrayed throughout the rear of the panel, with zones that can be independently adjusted. The effect of this is that darker areas of shadow and black colour will be more accurate, while highlights and brighter images will be boosted. X-tended Dynamic Range and the independent zones of lighting mean that these contrasting tones aren't mixed, and an even and accurate picture is displayed in your room. Colours benefit from the Full Array LED lighting in conjunction with a TRILUMINOUS panel - the screen is designed to display a wider range of shades to take advantage of extra luminance produced by the advanced lighting system. Your TV will then apply Object-based HDR remastering to the picture, altering the colouring of individual objects detected on screen in line with the focus of the image. 4K upscaling of detail adds definition to your watching. 4K X-Reality PRO is the feature of the X1 processor that manages this with algorithms - the TV uses a library of tens of thousands of images showing before and after improvement mastered by Sony, these are then used to evaluate your on-screen viewing and apply these improvements as you watch. A 100Hz panel is used in this TV for improved motion quality, refreshing the picture faster than a standard 50Hz TV. X-Motion Clarity is then applied by the TV processor to track brightness levels as the screen refreshes and make sure that brilliance isn't lost. This results in reduced blurring and a smoother image. Speaker quality is improved by the inclusion of Acoustic Multi-Audio in the 75" XH90 series. This upgrade to conventional TV speakers adds extra tweeters hidden inside the television frame, which then project sound from the centre of the screen in line with the action on-screen. An Android operating system provides catch-up TV from BBC iPlayer, 4 On Demand, ITV Hub and My5. Easy streaming from Netflix, Amazon Prime Video and Disney+ can be navigated from the list of apps available, with Netflix even having a dedicated picture pre-set to make the most of the original source quality. Many TV functions can also be controlled by Alexa or Google Assistant, just hold a button on the remote and ask away. The Google Play store is full of apps designed to work on your TV, and is worth a browse to see what else is available. HDMI 2.1 compatibility allows use of motion and control-improving measures for gaming such as Variable Refresh Rate (VRR) and Auto Low Latency Mode (ALLM). These will match the capabilities of newer gaming systems and the screen quality to ensure clear motion, and give faster responsiveness from control commands via reduced input lag.
