I viewed mostly standard HD (1080i, 720p and 1080p) content on the Sony, and in all the TV did an excellent job of scaling to the set’s native 4K resolution. Detail was always rich, and the TV’s very good black level made everything pop. The high resolution, even when not looking at native 4K material, creates a better fill ratio on the screen than a standard 1080p TV of similar size. This was apparent when I wandered over to a 90-inch Sharp 1080p TV in another part of the store. I’m not a neurologist or an ophthalmologist, so I can’t say with authority how small a pixel we’re able to perceive, but I believe the eye knows when something’s missing. More pixels on the screen and less space between them mean there’s more picture information for the brain. The result is a smoothness and depth that’s hard to quantify, but if you’ve sat in front of these TVs you know what you’re looking at. The perceived depth, which is helped by the contrast ratio as much as the resolution, was almost the best I’ve seen.
As I’ve said before in other articles, 3D on a 4K TV is also an improvement, but for a different reason. With 4K, you can have full 1080p for each eye without active glasses, which is why all the new 4K TVs uses passive, polarized glasses (the Film Pattern Retarder method first introduced by LG). On the Sony, 3D Blu-ray movies were excellent. I find the polarized glasses more comfortable both to wear and to look through. There was occasionally some shimmer on edges in the image and a little ghosting, especially around the microphone on the 3D Blu-ray of Goldberg Variations, but it wasn’t significant and was easy to dismiss. Some of this I think was the fault of the content and not the TV, because other 3D movies looked perfect.
While the TV was connected to a 4K content server supplied by Sony (which was actually just a Dell computer), it didn’t have the full suite of 4K content that buyers of the TV receive. Instead it contained a few music videos, including an unbearable Taylor Swift music video. As much as I hate that song, the picture was stunning. Note to Sony: The target market for this TV is probably not middle school girls, so maybe rethink your included content.
It’s also worth pointing out that the speakers on this TV—10 of them built into two left and right bars—sounded excellent. With this model, and the TVs which Sony unveiled earlier this month at CES, it’s clear the company wants to up the sound ante on built-in speakers. The speakers on the XBR-84X900 include four bass drivers, and the bass was impressive, with a wide overall soundstage and good detail. However, the speakers are removable, so if you’re going to make this part of a whole home theater room, you don’t have to leave those big things attached to the side.
After I was done fiddling with the TV I sat down with Hi Fi House president Jon Robbins. He says that for his customers, those looking for better-than-average products, 4K is the next sensible step in television. In fact, it’s not a demand for 4K content that’s sparking curiosity as much as the demand for good video processing. “We’re actually showing the TV more with cable and Blu-ray than we are the 4K content, because what it does for standard HD is astounding,” he says.
