LG OLED evo C4 Series (2024) vs Sony BRAVIA XR X90L Full Array LED 4K TV (2023)
The LG OLED evo C4 Series (2024) is the premium option here, especially for gamers, thanks to its impressive 144Hz refresh rate. In real-world use, this feature makes fast-paced action and gaming feel incredibly smooth, while the Sony BRAVIA XR X90L Full Array LED 4K TV (2023) shines in brightness with a peak brightness of 1200 nits, making HDR content pop like never before.

So, the choice here really depends on whether you prioritize gaming performance or cinematic brightness. Key specs: Refresh: 144 Hz vs 120 Hz and HDMI Ports: 4 vs 2 (one shared with eARC).
Why compare these? Both the LG OLED evo C4 Series (2024) and Sony BRAVIA XR X90L Full Array LED 4K TV (2023) are high-end tvs competing in the same market segment. This makes them direct rivals for buyers looking for high-end features and performance in 2026. Understanding their differences helps you choose the right one for your specific needs.
