Questions - Wayne wants to get a 4K TV. What model should he get, the Vizio P Series or the Sony Bravia? The Sony X900F is about $2000, and the Vizio P Series is close to the same price. Scott says don't get the X850F, even though it's $500 cheaper. It has an edge lit LED backlight, and that could cause uneven lighting. The X900F and the Vizio P series use full array local dimming, so it's illumination is more uniform and has better contrast. Worth the extra money.
