LG C5 48" 4K Ultra HD OLED evo AI Smart TV - OLED48C54LA

The primary distinction between the LG OLED48C54LA and the LG OLED42C54LA lies in their screen dimensions, as the former offers a larger 48-inch display compared to the latter's 42-inch panel. This size difference naturally impacts the physical dimensions and weight of each unit, with the 48-inch model being significantly larger and heavier overall. Beyond size, the two models share crucial core specifications, including the same 144 Hz refresh rate, identical OLED evo screen technology, and 4K Ultra HD resolution, ensuring similar high-end picture quality. While many features are shared, the 42-inch model reports slightly lower energy consumption in both SDR and HDR modes, likely due to its smaller screen size. Ultimately, the choice hinges on whether you prioritize a larger viewing area or a more compact fit for your space.
