As the replacement to last year's Samsung NU7100, it's no surprise that the newer RU7100 sports a very similar design., As one of Samsung's most affordable 4K TVs, the RU7100 offers full 3840 x 2160 resolution, a 60Hz refresh rate and decent picture quality., The RU7100 has a pair of 10-watt speakers inside, delivering a total of 20 watts of power. That translates into great volume, getting loud enough to fill our test lab, and it even offered some unexpectedly hefty bass for a TV that has no subwoofer.
