We’ve tested 2017 OLED TVs from LG, Panasonic and Sony side by side in a comprehensive manner – all of them are fantastic displays, though one might do some things better than the other two, and vice versa. The aces up Sony’s sleeves are class-leading upscaling, suppression of posterisation and least-artefact-prone motion interpolation, thanks to the KD-65A1′s X1 Extreme processor and [Smooth Gradation] super bit-mapping technology.
Perhaps the highest compliment we can pay to the Sony A1 is that it’s the most forgiving OLED that makes the best of all types of content, even ropey, bit-starved ones. With the promise of Dolby Vision support to come, the Bravia KD-65A1BU is a must-audition for anyone in the market for a large-screen television this year.
In other words, the Sony KD-65A1 is primarily optimised for HDR videos that are mastered at 1000 nits, and will clip (read: discard) most highlight detail between 1000 nits and 4000 nits during playback of 4K Blu-rays that are mastered to 4000 nits.

LG’s tone-mapping for HDR10 Ultra HD Blu-rays favours preserving highlight detail over overall brightness of the HDR image. In other words, even in 4K Blu-ray movies that are mastered to 4000 nits, all the specular highlights will be intact without being blown out, though the overall picture can look a bit darker than the competition.
