LG C5 42" 4K Ultra HD OLED evo Smart TV - OLED42C54LA

The LG OLED42C54LA (C5 Series) and the LG OLED42C44LA (C4 Series) are both high-quality 42-inch 4K OLED evo televisions sharing identical physical dimensions and core connectivity like four HDMI 2.1 ports and 144 Hz refresh rates. A key distinction lies in audio processing, as the newer C5 model appears to focus on an enhanced built-in speaker configuration, while the C4 explicitly lists broader audio format support including DTS and DTS:X alongside Dolby Atmos. Furthermore, the C4 series includes support for Google Cast/Chromecast in its streaming standards, a feature not explicitly listed for the C5 model. For most core display features and general use, these models are extremely similar, making the choice dependent on specific audio codec needs or preferred streaming ecosystem support.
