“Hi. I bought a 50NU7400 to replace my old Samsung TV. In fact, I've been a solid customer more than a decade and owned several 6/7 series models. But it was time to move to 4k/UHD. Since opening the box I've noted that more than half my collection won’t play on this device via USB. Usually it’s the audio codec not supported by Samsung TV.
