LG OLED evo C4 Series (2024) vs VIZIO Quantum Pro QLED 4K TV (2023)
The LG OLED evo C4 Series (2024) is the premium option here, boasting a stunning 144Hz refresh rate for ultra-smooth gaming. In contrast, VIZIO Quantum Pro QLED 4K TV (2023) offers a solid performance but lags behind in refresh capabilities with only 120Hz support. In real-world use, this means that for gamers, the LG's refresh rate delivers a seriously impressive experience, especially when paired with its four HDMI 2.1 ports. Meanwhile, VIZIO's single 4K@120Hz HDMI port limits multi-console setups, making it less appealing for serious gamers who want seamless switching.
