The Sony Bravia XR-75X90J 75-Inch 4K LED TV relies on a full-array local dimming backlight. And Cognitive Processor XR to deliver bright, evenly lit images across its large 75-inch panel, while the LG C1 55 4K 120Hz OLED Smart TV uses self-emissive pixels to achieve perfect blacks. And instant response times on its smaller 55-inch screen. Public reviews consistently note the Sony’s strong color volume and four HDMI 2.1 ports that support 4K at 120 Hz for gaming, whereas the LG earns praise for its infinite contrast, lower input lag, and webOS interface. Brightness levels favor the LED model in well-lit rooms, but the OLED’s pixel-level control produces noticeably deeper shadows in dark viewing environments. The short version: choose the Sony Bravia XR-75X90J for maximum screen size and connectivity or the LG C1 for superior contrast and a substantially lower price.

Verdict: Pick Sony Bravia XR-75X90J if you need the biggest 75‑inch screen and four HDMI ports; pick LG C1 if you prefer OLED’s infinite contrast and a $900 lower price. Sony wins on size, LG wins on picture quality and value.

Sony Bravia XR-75X90J 75-Inch 4K LED TV lists at $3,500 while LG C1 55 4K 120Hz OLED Smart TV lists at $1,299 — LG C1 55 4K 120Hz OLED Smart TV undercuts Sony Bravia XR-75X90J 75-Inch 4K LED TV by $2,201 (169%).

Winner: LG C1

Sony Bravia XR-75X90J 75-Inch 4K LED TV: 7.5/10
