Panasonic HCX Video Processing Engine

First used in Panasonic’s high-end OLED TVs, the HCX (Hollywood Cinema eXperience) processor harnesses decades of Panasonic picture knowhow in a single chip. Tuned by leading Hollywood colourist, Stefan Sonnenfeld, this Panasonic 40 inch TV delivers total picture accuracy and remains true to the director’s vision.

Maximises HDR – including HDR10+
For the highest quality picture, HDR10+ offers scene-by-scene HDR mastering for the truest, most accurate HDR picture technology to date. With HDR10+ each scene is optimised, meaning the maximum amount of detail is shown – even in the brightest or darkest moments. The TX40GX800 also supports standard HDR10 and HLG formats. HLG (Hybrid Log Gamma HDR) is a broadcast and user generated standard format that is set to become the standard for transmitting 4K signals.

Dolby Vision for dramatic imaging
As well as supporting HDR10+, the TX40GX800 is also compatible with Dolby Vision - a leading format in Hollywood and cinemas around the world. Dolby Vision also adjusts the picture to take full advantage of each display's characteristics and presents an optimized picture for each scene in specially mastered content.

Local Dimming for breath-taking detail
Thanks to Local Dimming, this Panasonic 40” TV brings out the best in any image - whatever the resolution. Whether 4K UHD, 1080p FHD or standard definition, Local Dimming adjusts the brightness of the screen by zones. This gives greatly improved contrast, as the black sections of the TV can be darker and the whites brighter.
