CES 2019 - Sony isn't going to be pushed out of the 8K TV market with an announcement of its new Master Series TVs that include 4K and 8K models split between OLED and LCD panels, respectively.
The flagship Z9G 8K uses an LCD panel for its 7680 x 4320 native resolution while the A9G 4K OLED TVs that come in 55/65/77-inch sizes while the 8K sets are larger 85-inch and a huge 98-inch in size. All of the new TVs will feature Sony's own Picture Processor X1 Ultimate, with the company adding it "has a unique algorithm specially developed for 8K that can intelligently detect and analyze each object in the picture, resulting in exceptional detail and contrast for a more realistic picture that represents the creators' intent".
Sony's first consumer-focused 8K TV is the new Z9G, with Sony touting: "Completely new dedicated 8K technologies have been developed for the Z9G series, including a Backlight Master Drive feature with full-array local dimming and 8K X-tended Dynamic Range PRO. The Backlight Master Drive on the Z9G has ultra-dense LED modules that are independently controlled, delivering unprecedented contrast with punchy brightness and pitch blacks. To optimize this backlight system, 8K X-tended Dynamic Range PRO uses the saved energy to intelligently boost the brightness in the areas where it needs to be boosted".
Don't worry about your trusty old 4K content as the company is talking up its proprietary algorithm for 4K content upscaling to "near-8K" quality, with Sony using an "8K database to refer to for even more precise, detailed upscaling".
