The 4K revolution may be in its infancy, but Sony is banging on the crib bars with the newly announced XBR-84X900. It’s Sony’s first TV ever with 3,840×2,160-pixel resolution (four times as detailed 1080p), and it’s also the biggest Sony screen to date. The edge-lit LED-based LCD display features passive 3D (also a Sony first) and a detachable 10-driver stereo speaker system lets you rumble the living room with sound. This way you don’t have to listen to that brat whine about “being hungry” and “needing a diaper change.” Kids.
