Samsung OLED S90D Series (2024) vs VIZIO Quantum Pro QLED 4K TV (2023)
For ultimate display quality, the Samsung OLED S90D Series (2024) crushes the VIZIO Quantum Pro QLED 4K TV (2023) with its perfect black levels and peak brightness of 1,200 nits. In contrast, the VIZIO's low native contrast means blacks can appear gray, especially in darker rooms. The Samsung OLED is the premium option, offering remarkable color volume and brightness, particularly in the QD-OLED models. However, if you're in a bright room and need wide viewing angles, the VIZIO's IPS-type panel shines but lacks the deep blacks that make movies pop. After testing both, it's clear that the Samsung OLED is a no-brainer for serious home theater enthusiasts.
