Even with the Smart TV features this TV is the top class in every way. The operation is in parts even better than my expensive LG.
Only the critical scale of low-resolution material (under SD level, eg QVGA as in the Tagesschau app uses) does not work as well as in the top echelon. My LG scaled even QVGA material almost perfectly on the big screen. QVGA like this Samsung on the other hand do not, as it looks quite quite distinct blocks.
However, QVGA is rare for this money a sensational TV.
