Samsung OLED S90D Series (2024) vs Hisense U6N Mini-LED ULED 4K Google TV (2024)
The Samsung OLED S90D Series (2024) crushes the Hisense U6N Mini-LED ULED 4K Google TV (2024) when it comes to display quality, boasting a stunning 144Hz refresh rate compared to just 60Hz on the Hisense. This means smoother gameplay and a more responsive viewing experience, especially for serious gamers or movie enthusiasts.
