4K TV: What the heck is it and what can I watch?
In the next couple of weeks, the XBR-84X900 television will ship to customers who placed pre-orders since the product introduction in September. As an extra bonus, included free with the purchase will be the world’s first 4K Ultra HD delivery solution, complete with pre-loaded, native 4K entertainment. Not some goofy 4K content shot as a demo. I’m talking full length feature Hollywood productions, and available exclusively to purchasers of Sony’s 84” 4K Ultra HD TV.
