The LG OLED55CXPUA and the Sony Bravia X90J represent two distinct approaches to mid-2021 television performance, one built on LG Display’s self-emissive OLED panel. And the other on Sony’s full-array LED backlight with local dimming. Public specifications show the LG model delivering perfect blacks and instantaneous pixel response, while the Sony Bravia X90J counters with higher sustained brightness. And a wider color volume courtesy of its Mini LED-like backlight and X1 processor. Review aggregation sites consistently note the LG OLED55CXPUA’s superior motion clarity. And near-infinite contrast, whereas the Sony Bravia X90J earns marks for smoother upscaling of lower-resolution content and more accurate factory color tuning out of the box. Neither manufacturer has released official figures for peak brightness, exact HDMI 2.1 port counts, or full VRR and ALLM support at launch, leaving those details to third-party teardowns. On the figures both makers publish, the Bravia X90J leads with a lower starting price of $1,299 versus $1,799 for the OLED55CXPUA. Bottom line: buyers prioritizing deep blacks and crisp gaming response lean toward the LG, while those seeking brighter rooms and refined SDR-to-HDR conversion often favor the Sony.

Verdict: On the figures both makers publish, the Bravia X90J leads with lower starting price ($1,299 vs $1,799). Neither publishes peak brightness, HDMI 2.1 ports or VRR / ALLM yet.

LG OLED55CXPUA lists at $1,999 while Sony Bravia X90J lists at $1,599 — Sony Bravia X90J undercuts LG OLED55CXPUA by $400 (25%).
