The Sony X80J 55 4K 120Hz LED Smart TV relies on a conventional LED backlight. And Google TV platform to deliver straightforward 4K performance at a lower price point, while the LG C1 55 4K 120Hz OLED Smart TV uses self-emissive pixels for deeper blacks, wider contrast range. And more accurate color reproduction drawn from its OLED panel and α9 Gen 4 processor. Public reviews note that the Sony model offers reliable brightness for everyday rooms. And includes four HDMI ports along with native Google TV integration, whereas the LG model stands out for its motion clarity at 120 Hz, support for Dolby Vision. And near-instantaneous pixel response times that reduce blur in fast scenes. Both sets omit HDMI 2.1 and variable refresh rate, limiting their appeal for high-end gaming setups. Bottom line: choose the Sony X80J for budget-conscious viewing with solid connectivity or the LG C1 when superior contrast and motion handling justify the added cost.

Verdict: Pick Sony X80j if you need a budget‑friendly 4K TV with Google TV and four HDMI ports at $699.99. Pick LG C1 if you prioritize OLED picture quality, 120Hz motion and Dolby Vision at $1,199.99. Both lack HDMI 2.1 and VRR, so if those features are essential, skip both.

Sony X80j 55 4K 120Hz LED Smart TV lists at $1,599 while LG C1 55 4K 120Hz OLED Smart TV lists at $1,299 — LG C1 55 4K 120Hz OLED Smart TV undercuts Sony X80j 55 4K 120Hz LED Smart TV by $300 (23%).
