Scott put in his customary 28 miles of walking during CES and he saw some really cool TVs. One thing he saw was a TV with Dual Layer Modulation LEDs, which uses two LED screens to deepen color and dynamic range. The one behind is black and white only, which is used to dim each pixel separately. The contrast ratios are approaching 1 million to one! HiSense had one with 3000 nits of brightness and a black level of .0003. MicroLEDs were also huge. Samsung showed off a 75" 4K microLED that was huge.
