na prática alguns usuários do htforum q tiveram as 2 preferiram a 905F.Sério?
O site da Rtings dá a seguinte comparação:
The Samsung Q70 QLED is slightly better than the Sony X900F. The Q70R has a slightly better dark room performance, thanks to the higher contrast ratio and better black uniformity. The Q70R is also better for gaming as it's packed with gaming goodies, like a lower input lag. The Sony X900F can get brighter in SDR and has slightly better reflection handling, which is great if you watch TV shows in a bright room with many lights. Also, motion is somewhat crisper on the Sony X900F thanks to the faster response time, which is great for watching fast-action sports.
superior a ela é a Q80.
Pra jogos a Xamxung tem o input lag menor.
Pra filmes/séries a Sony dá um banho, cores mais naturais, HDR lindão, pouco blooming.
Xamxung soca as cores estouradas pra chamar atenção.
Como se diz: A Sony trabalha com realismo, a Xamxung com ilusionismo.
