Sony's 56-inch 4K OLED TV is able to display at a resolution of 3,840 x 2,160 and is filled with Sony's oxide semiconductor TFTs and Super Top Emission technologies, which as long as that means we're able to view 4K on an OLED TV, then that's good enough for us. The 56-inch 4K OLED TV prototype didn't come with any mention of any other specs we expect to hear from an official announcement of a new TV set, which makes sense since this is, in fact, a prototype.
