Samsung QE55QN90B and Sony XR-55X90K are both 55-inch 4K TVs built around VA panels with full-array local dimming, yet they diverge in color reproduction and audio design. The Samsung QE55QN90B relies on its Quantum Dot layer to deliver wider color volume. And more saturated hues, paired with one of the narrowest bezel profiles in its price range. The Sony XR-55X90K instead centers on the Cognitive Processor XR, which handles motion and upscaling with deliberate attention to scene coherence. And augments the picture with an Acoustic Multi-Audio system that uses the screen itself as part of the speaker array. Public reviews note the Samsung’s stronger HDR pop in bright rooms while praising the Sony’s more natural tonal transitions and clearer dialogue reproduction. Neither manufacturer publishes exact power consumption, internal storage capacity, or precise dimensions and weight for these models, leaving those details to retailer listings that can vary by region. Bottom line: choose the Samsung QE55QN90B for vivid color and minimal frame, or the Sony XR-55X90K for refined processing and integrated sound.

Verdict: The Sony XR55X90K delivers more natural colors in dim settings but falls short on brightness and lacks HDMI 2.1 VRR, making it a secondary choice for cinephiles on a tighter budget. Choose the Samsung if you prioritize HDR gaming and bright‑room viewing; choose the Sony if you value color accuracy in a dark room and want a lower price point.
