Our Verdict
LG CX OLED
LG NANO90 2021
The LG CX OLED is much better than the LG NANO90 2021, mainly because they use different panel types. The CX has an OLED panel that displays perfect blacks, thanks to its near-infinite contrast ratio. Also, there's no blooming around bright objects. Each TV has the same gaming features with a 120Hz panel and HDMI 2.1 inputs, but the CX has a near-instantaneous response time for smooth motion. On the other hand, the NANO90 has an LED panel that doesn't have the permanent burn-in risk associated with OLEDs, and it gets brighter.
