The world of home entertainment technology is evolving at breakneck speed. In the same way flat-screen televisions made the tube television as quaint as a rotary phone virtually overnight, the once familiar plasma display panels are now on the way out.
They are being replaced by 4K display, which delivers 4,000 pixels of resolution, a huge leap over the current home high-definition format, which maxes out at 1,080 pixels. The 4K display televisions range in size from 39 to 85 inches and prices, accordingly, range from $500 to $40,000.
