Speaking of top-of-the-line, this TCL features Mini-LED, a technology that isn't found on any other TV currently available. The result is superb contrast and brightness that outdoes the Vizio PX by a nose, although it doesn't quite hit OLED levels. We still consider the PX a better OLED alternative, however, because its picture quality is almost as good and it costs a lot less, especially in the 75-inch size.
