XBR75X940D vs XBR75X850D

Unlike the XBR75X850D, the XBR75X940D has a full-array local dimming (FALD) backlight. The 75-inch X850D model, on the other hand, has an edge LED backlight with no local dimming capabilities. Having the LEDs spaced evenly behind the screen, in addition to being able to individually boost or dim specific LED zones allows the X940D to reach higher peak brightness and lower black level at the same time. The X-tended Dynamic Range PRO paves the way for a wider brightness range on the X940D. Thus, especially when used with HDR (High Dynamic Range) content, it can deliver more true-to-life picture quality, with greater contrast and color. While the X850D is also 4K HDR compatible, as designated by Sony, the lack of the X-tended Dynamic Range technology (either PRO or basic version) means the HDR content cannot live up to its full potential since it requires brighter peaks and deeper blacks - something that the edge mounted LED module of the X850D isn't able to achieve, especially considering there is no local dimming in place. Instead, there is only frame dimming but it dims the entire frame, which is counterproductive with HDR.

The X940D and X850D can reproduce wider range of colors thanks to the TRILUMINOS Display. In order to prevent colors of becoming oversaturated and unnatural, the dynamic color correction technology selectively maps colors across the wide gamut. The two series are equipped with 4K X-Reality PRO picture processing engine meaning they have similar HD to UHD upscaling capabilities.

There is an optional flush mount system for the X940D which allows the TV to mounted closer to a wall. The X850D is not compatible with this system. If you prefer placing the TV on its base, you should know that both series have a cable management system for routing the cords through the stand. That said, the X940D goes a step further by fully concealing them behind the panel, thanks to a hidden cable panel structure.

Unlike its predecessor, the X940D doesn't have the more powerful side mounted speakers and larger woofers, which leads to the total audio power output being equal on the X940D and the 75-Inch X850D model: 30 Watts (7.5 W x 4). The rest of the X850D series have 20 Watts (10w x 2) of sound output power. However, both series support the SWF-BR100 wireless subwoofer as an optional accessory.
