The Samsung RU8000, which also forms the link between the RU7100 and the Q-series, was released last year. In contrast to the RU8000, the TU8000 offers better smart features, but if you can do without it and find the RU8000 at a good price, you definitely won’t go wrong.
In the past, Samsung has simply moved the numbers of new TVs up several times in order to make them sound better and ultimately sell better. But if you compare the TU8000 with the 2019 models, it is very similar to the Samsung RU7400.
The Samsung Q60T, as the most affordable 2020 QLED, is moving closer to the entry-level models than was previously the case. The Q60T has of course the Quantum Dot layer and thus also a wide gamut. It also has a slightly deeper black because of the dual LED technology and it comes with a higher brightness. So it has an advantage with HDR material.
