TCL Class S4 4K LED Smart TV (S4 / S450G) vs Hisense U6N Mini-LED ULED 4K Google TV (2024)
The Hisense U6N Mini-LED ULED 4K Google TV (2024) comes out ahead thanks to its impressive peak brightness of 600-700 nits, making HDR content look vibrant and full of life. In contrast, the TCL Class S4 4K LED Smart TV (S4 / S450G) struggles with only 250 nits, meaning HDR lacks that visual punch you want in bright scenes. With its Mini-LED backlighting, the Hisense model boasts better contrast ratios at approximately 40,000:1 compared to the TCL's high native contrast of around 5000:1. So, if you want a TV that shines in both dark and well-lit rooms, the Hisense U6N is a no-brainer for your viewing pleasure in 2024.
