Samsung QN90A 55-inch 4K UHD TV review: Mini-LED meets quantum dots

Samsung's Neo QLED QN90A takes the company's already outstanding QLED color and brightness and, thanks to far more granular mini-LED backlighting, enhances it with far better blacks. The overall result is truly impressive, although Samsung still has some work to do on its zone dimming techniques. The 54.6-inch (55-inch class) version of the QN90A I tested currently retails for around $1,700 and features a 4K UHD (3840 x 2160), 120Hz, 10-bit display. Said display implements quantum dots for accurate, saturated color, and mini-LEDs for refined backlighting. Mini-LEDs, as you might guess, are far smaller than traditional backlight LEDs.
