Expert review

This is it, Sony's Master Series. Few manufacturers have the bravery to give a series of TVs such a bold moniker, but Sony does. Such confidence could go either way, but the signs are good that the 55-inch Sony KD55AG9BU, released in 2019, could be a world beater. It uses Sony's X1 Ultimate processor, which promises unmatched clarity at all resolutions as well as the acoustic surface screen vibrating audio that has worked well in the past. Is this OLED the best around? Let's find out.
